[아이폰 앱 개발] Display the Network Activity Status Indicator

Display the Network Activity Status Indicator

This is the rotating icon displayed on the iPhone status bar in the upper left to indicate there is background network activity taking place.

  UIApplication* app = [UIApplication sharedApplication];
  app.networkActivityIndicatorVisible = YES; // to stop it, set this to NO

[아이폰 앱 개발] iphone crash log 위치 on the MAC 및 로그까는 symbolicatecrash프로그램 및 설치하기 명령어

IPhone Crash Logs

Sometimes programs crash. This annoys users and developers alike. Users are frustrated because they cannot use crashing software, developers are frustrated because they have to hunt bugs instead of doing something creative and rewarding. How do we communicate if an iPhone application crashes?

I’ll start with a disclaimer. I’m not sure whether the information provided in this post is covered by iPhone Developer Program NDA or not. If it is, the post will be removed. Secondly, this post is a result of googling, so I haven’t invented anything new here.

Working with crash logs typically involves certain interaction between developers and users, unless they are automagically sent to the developer. First of all, the user should get the crash log and send it to the developer, who should examine it, find the bug and fix it.

iPhone OS and Mac OS X are remarkably similar architectures. Both store crash logs to help identify crashing bugs. The difference between the two is how users retrieve them. On Mac OS X every user has unrestricted access to crash logs related to the applications she runs. The iPhone does not even have a file browser. What to do? iTunes comes to the rescue.

Whenever you synchronize your iPhone or iPod Touch, all the crash logs are transferred to your computer. Here are their locations:

Mac OS X:~/Library/Logs/CrashReporter/MobileDevice/<DEVICE_NAME>
Windows XP: C:\Documents and Settings\<USERNAME>\Application Data\Apple computer\Logs\CrashReporter/<DEVICE_NAME>
Windows Vista: C:\Users\<USERNAME>\AppData\Roaming\Apple computer\Logs\CrashReporter/MobileDevice/<DEVICE_NAME>

The log file names start with application name and have the extension “crash”. They are just plain text files and can be sent by e-mail in original or zipped form, or even copy-pasted into your e-mail program.

The second part is trickier. Both Apple and common sense suggest that all AppStore binaries are shipped with stripped symbols. If you ever saw a crash log like this, read on:

In a nutshell, it contains function addresses and offsets instead of function names and line numbers. The structure is obvious, but, to be honest, I don’t know what “MobileLines 0×00006434 0×1000 + 21556″ is, even though I have all the source code. Thanks to Apple Developer Tools and to Craig Hockenberry who wrote about it, we have a perfect solution called symbolicatecrash.

위의 크래쉬로그를 가독성있게 분석할 수 있도록하는 툴

/usr/local/bin/으로 위의 프로그램 옮기고

$ sudo cp /Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneRemoteDevice.xcodeplugin/Contents/Resources/symbolicatecrash /usr/local/bin/

위의 명령어로 설치하고

$ symbolicatecrash report.crash MobileLines.app.dSYM > report-with-symbols.crash

통해 크래쉬로그를 가독성있도록 바꿈

I copied it to /usr/local/bin/ so that I can run it whenever I want without trying to remember its original location (you may prefer a symbolic link):
$ sudo cp /Developer/Platforms/iPhoneOS.platform/Developer/Library/Xcode/Plug-ins/iPhoneRemoteDevice.xcodeplugin/Contents/Resources/symbolicatecrash /usr/local/bin/

Running this script with the -h option provides the minimal help:

$ symbolicatecrash -h usage:

symbolicatecrash [-Ah] LOGFILE [SYMBOL_PATH ...]

Symbolicates a crashdump LOGFILE which may be "-" to refer to stdin. By default, all heuristics will be employed in an attempt to symbolicate all addresses. Additional symbol files can be found under specified directories.

Options: -A Only symbolicate the application, not libraries -h Display this message -v Verbose

To add symbols to the crash log you need the dSYM file generated by the linker when you compiled your application for AppStore. In other words, when you build for AppStore you should keep the dSYM package in a safe place backed up by Time Machine. This is very important. You should keep a copy of the dSYM for each version of your application ever shipped. If you have the package, translating code offsets to function names with line numbers has never been easier:

$ symbolicatecrash report.crash MobileLines.app.dSYM > report-with-symbols.crash

[아이폰 앱 개발] CATransition showing a single frame from the end of the transition before the animation starts

CATransition showing a single frame from the end of the transition before the animation starts

I am using some code which was originally taken from the Apple sample ViewTransitions to swap two views with each other.

CATransition *animation = [CATransition animation];
[animation setDelegate:self];
[animation setType:kCATransitionFade];
[animation setDuration:0.3f];
[animation setTimingFunction:[CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionLinear]];
[[container layer] addAnimation:animation forKey:@"swap"];

When my transition executes on the devlice, I sometimes get a single frame flash of the final frame of the transition animation and then the animation plays smoothly. This gives a very jarring effect of the 2nd view which flickers in and then out again before the smooth animation executes.

The main difference between my example and the Apple example is that my views are not full screen, I have a container UIView which contains both sub-views and I am applying my animation to the container layer instead the root view layer. I can not see that this should make much difference though.

This issue does not happen at all in the simulator and is intermittent (about 60-70% of the time) on the device. Is anyone else seeing this behaviour and if so, how did you work around it?

Updated with more information: The code was originally part of a multi part animation but I moved it to be triggered by a button to isolate the problem. The issue occurs in both situations.

The animation delegates were implemented but have been removed to try and isolate the problem.

The views are not changing during the animation and in fact [container setUserInteractionEnabled:NO] is being called (but the problem also happens without user interaction being disabled).

I have tried starting the animation from the middle of the transition and ending before the end usingsetStartProgress and setEndProgress, again the problem persists.

I have tried slowing the animation duration right down as well with no effect.

	I can't post comment, but the same as teabot : I did what you said and it doesn't do the trick... Do you have more explanations on the subject ?
	1410428 Unfalkster iphone cocoa-touch core-animation objective-c

Solved, I had missed a key piece of this that I thought was irrelevant ;) After setting up the animation in the code sample above, I was swapping the views out in the same method.

Moving it to the animationDidStart delegate fixed the issue.

iphone cocoa-touch core-animation objective-c

Can you give some example code of this in action please? I have implemented what I understand by your description but my 'glitch frame' persists. #1226703

teabot

To begin to answer your question more information is needed - for instance, how are you calling that code (e.g. is it bound to a button as an action or is it triggered automatically somehow), have you implemented the delegate methods to start and stop the animation (and what is contained within them), and are your views changing at some point during the animation? Timing between the simulator and device will be off - you should not rely on the simulator to test animation as everything will happen quicker.

how to make a UITextField move up when the keyboard is presented


아래 답변대로 하되 매크로설정빼먹으면 오류~ 매크로수치만큼 뷰가 위로올라간다. 뷰가 움직이는 것이 감지되나 여전히 가리면 아래 매크로값을 조정하면 된다.


일반 뷰에 텍스트필드가 있을때에도 가능하다.


#define kOFFSET_FOR_KEYBOARD 120.0

With the iPhone SDK:

I have a UIView with UITextFields that brings up a keyboard. I need it to be able to:

Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up
Automatically "jump" (by scrolling up) or shortening

I know that I need a UIScrollView. I've tried changing the class of my UIView to a UIScrollView but I'm still unable to scroll the textboxes up or down.

Do I need both a UIView and a UIScrollView? Does one go inside the other? [EDIT: I now know that you want a UIView inside of a UIScrollView, and the trick is to programatically set the content size of the UIScrollView to the frame size of the UIView.]

Then what needs to be implemented in order to automatically scroll to the active text field?

Ideally as much of the setup of the components as possible will be done in Interface Builder. I'd like to only write code for what needs it.

Note: the UIView (or UIScrollView) that I'm working with is brought up by a tabbar (UITabBar), which needs to function as normal.

http://stackoverflow.com/questions/1126726/how-to-make-a-uitextfield-move-up-when-keyboard-is-present

Edit: I am adding the scroll bar just for when the keyboard comes up. Even though it's not needed, I feel like it provides a better interface because then the user can scroll and change textboxes, for example.

I've got it working where I change the frame size of the UIScrollView when the keyboard goes up and down. I'm simply using:


-(void)textFieldDidBeginEditing:(UITextField *)textField { //Keyboard becomes visible scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y,                                                    scrollView.frame.size.width, scrollView.frame.size.height - 215 + 50); //resize } 
-(void)textFieldDidEndEditing:(UITextField *)textField { //keyboard will hide scrollView.frame = CGRectMake(scrollView.frame.origin.x, scrollView.frame.origin.y,                                                     scrollView.frame.size.width, scrollView.frame.size.height + 215 - 50); //resize }

However this doesn't automatically "move up" or center the lower text fields in the visible area, which is what I would really like.

1) You will need a scroll view if the contents you have now does not fit in iphone screen. [If you are adding the scroll view just to make the textfield scroll up when keyboard comes up, then its not needed]

2) For showing the textfields without being hidden by the keyboard, the standard way is to move up/down the view having textfields whenever the keyboard is shown

here is a sample code


-(void)textFieldDidBeginEditing:(UITextField*)sender
{
    if([sender isEqual:_textField])
    {
        //move the main view, so that the keyboard does not hide it.
        if  (self.view.frame.origin.y >=0)
        {
            [self setViewMovedUp:YES];
        }
    }
}

//method to move the view up/down whenever the keyboard is shown/dismissed
-(void)setViewMovedUp:(BOOL)movedUp
{
    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];// if you want to slide up the view

    CGRect rect =self.view.frame;
    if(movedUp)
    {
        // 1. move the view's origin up so that the text field that will be hidden come above the keyboard 
        // 2. increase the size of the view so that the area behind the keyboard is covered up.
        rect.origin.y -= kOFFSET_FOR_KEYBOARD;
        rect.size.height += kOFFSET_FOR_KEYBOARD;
    }
    else
    {
        // revert back to the normal state.
        rect.origin.y += kOFFSET_FOR_KEYBOARD;
        rect.size.height -= kOFFSET_FOR_KEYBOARD;
    }
    self.view.frame = rect;

    [UIView commitAnimations];
}


-(void)keyboardWillShow:(NSNotification*)notif
{
    //keyboard will be shown now. depending for which textfield is active, move up or move down the view appropriately

    if([_textField isFirstResponder]&&self.view.frame.origin.y >=0)
    {
        [self setViewMovedUp:YES];
    }
    elseif(![_textField isFirstResponder]&&self.view.frame.origin.y <0)
    {
        [self setViewMovedUp:NO];
    }
}


-(void)viewWillAppear:(BOOL)animated
{
    // register for keyboard notifications
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) 
                                                                                         name:UIKeyboardWillShowNotificationobject:self.view.window]; 
}

-(void)viewWillDisappear:(BOOL)animated
{
     // unregister for keyboard notifications while not visible.
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillShowNotificationobject:nil]; 
}

define kOFFSET_FOR_KEYBOARD to a value as needed. like


#define kOFFSET_FOR_KEYBOARD 60.0

Hope this helps

As far as I know thats correct behavior. I've had that happen every time I've hidden the back button.

Try using.

The Basics of Protocols and Delegates

Posted on April 16, 2010 by John Muchow in Objective-C

http://iphonedevelopertips.com/objective-c/the-basics-of-protocols-and-delegates.html

Apple offers a good overview of working with protocols in their Objective-C Programming Reference. However, sometimes a simple working example can go a long ways…

Introduction

Protocols can be helpful in a number of scenarios, a common usage is to define methods that are to be implemented by other classes. A familiar example is when using a tableview, your class implements the cellForRowAtIndexPath method which asks for cell content to insert into a table – the cellForRowAtIndexPath method is defined within theUITableViewDataSource protocol.

Let’s walk through a very simple example of defining and adopting a protocol.

Protocol Definition

Here is an example of a protocol which includes one method, notice the instance variabledelegate is of type id, as it will be unknown at compile time the type of class that will adopt this protocol.

#import <Foundation/Foundation.h>   @protocol ProcessDataDelegate <NSObject> @required - (void) processSuccessful: (BOOL)success; @end   @interface ClassWithProtocol : NSObject { id <ProcessDataDelegate> delegate; }   @property (retain) id delegate;   -(void)startSomeProcess;   @end

Protocol Implementation

Inside the implementation section for the interface defined above we need to do two things at a minimum – first synthesize the delegate instance variable and second, call the method defined in the protocol as needed (more on that in a moment).

Let’s look at a bare bones implementation of the ClassWithProtocol.m:

#import "ClassWithProtocol.h"   @implementation ClassWithProtocol   @synthesize delegate;   - (void)processComplete { [[self delegate] processSuccessful:YES]; }   -(void)startSomeProcess { [NSTimer scheduledTimerWithTimeInterval:5.0 target:self selector:@selector(processComplete) userInfo:nil repeats:YES]; }   @end

Understand this is a rather contrived example – the intention is to show how/where one might use a protocol. For the sake of discussion assume you have a class that is processing (or downloading) some type of data. Further, assume this class is called from another class to begin the processing. Chances are, at some point the caller will want to be notified that the class processing the data is done, this is where the protocol comes in.

In the calling class, the method defined in the protocol, processSuccessful, will be implemented and will be called from the object doing the processing, once it is complete.

For this example, inside the class where the protocol is defined, I have one method,startSomeProcess, which simply starts a timer and calls processComplete after 5 seconds. Inside processComplete the calling object will be notified through its delegate that the process is done.

Adopting the Protocol

To keep the example short, I am using the applicaton delegate as the class that adopts the protocol. Here is how the app delegate looks:

#import <UIKit/UIKit.h> #import "ClassWithProtocol.h"   @class testAppObject;   @interface TestAppDelegate : NSObject <UIApplicationDelegate, ProcessDataDelegate> { UIWindow *window; ClassWithProtocol *protocolTest; }   @property (nonatomic, retain) UIWindow *window;   @end

A few things to note – ProcessDataDelegate is defined as part of the interface, which signifies that this class will adhere to the protocol. Looking back to the code for defining the protocol, notice that I added @required to the definition, which means that any class that adopts the protocol must implement the processComplete method (you will receive a compile warning if you don’t).

Here is the implementation of the app delegate and the required method for the protocol:

#import "TestAppDelegate.h" #import "ClassWithProtocol.h"   @implementation TestAppDelegate   @synthesize window;   UITableViewDelegate   - (void)processSuccessful:(BOOL)success; { NSLog(@"Process completed"); }   - (void)applicationDidFinishLaunching:(UIApplication *)application { // Create and initialize the window window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];   protocolTest = [[ClassWithProtocol alloc] init]; [protocolTest setDelegate:self]; [protocolTest startSomeProcess];   [window makeKeyAndVisible]; }   - (void)dealloc { [window release]; [super dealloc]; }   @end

How it all works

Things goes as follows: the app delegate will create a new instance of the ClassWithProtocolobject. It sets itself as the delegate and then calls the startSomeProcess method. At some point in the future, when the protocolTest object has completed its work – after the 5 second timer has fired – it will call the processSuccessful method in the app delegate to let it know it is done processing.

how to make a UITextField move up when the keyboard is presented

With the iPhone SDK:

I have a UIView with UITextFields that brings up a keyboard. I need it to be able to:

Allow scrolling of the contents of the UIScrollView to see the other text fields once the keyboard is brought up
Automatically "jump" (by scrolling up) or shortening
