UIImage imageWithContentsOfFile: not working on iOS8

When I test my app on iOS8 beta3 and beta5, I found an bug that about [UIImage imageWithContentsOfFile:].
When image resources are stored in sub-bundle of a main bundle, it will return nil if we initialize UIImage via the following method:
NSString *testBundlePath = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"bundleā€¯];
NSBundle *bundle = [NSBundle bundleWithPath:testBundlePath];
NSString *path = [bundle pathForResource:#"play.png" ofType:nil];
UIImage *image = [UIImage imageWithContentsOfFile:path]; //iOS8 image = nil, iOS7 image != nil
But when the image resources are stored in main bundle, UIImage Initialization can be succeed through the following method:
NSString *path = [[NSBundle mainBundle] pathForResource:#"play.png" ofType:nil];
UIImage *image = [UIImage imageWithContentsOfFile:path]; //iOS8 and iOS7 image != nil
We have found this problem under iOS8 beta3 and it still exists under iOS8 beta 5.
The Demo app directory structure was below:
XXX.app
|----test~ipad.bundle
|----play.png
|----test~iphone.bundle
|----play.png
|----play.png
|----play~iphone.png
|----play~ipad.png
......
Does anyone have the same problem? I think this is a bug on iOS8, Therefore, many apps have used bundle to organize resources, such as images. But now, this bug will make thousands of apps become ugly and hard to use. We really hope that Apple can fix this bug in the next version, otherwise, all of my app will have to developing an new version for this bug!
It's not actually broken, you're just sending it the wrong path.
I'm guessing that you are using the simulator, and have saved a file somewhere in your app and then made note of the full path to that file. However, when you rebuild your app the UUID for the installed app changes, and your saved path is no longer valid (even though the files are still there). You can see your current active path by checking [[NSFileManager defaultManager] currentDirectoryPath] Note that the value changes each time you rebuild and re-deploy your app.
To get to your actual file, you'll need to do something like this:
NSString *image = #"myImage.png";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES);
NSString *cache = [paths objectAtIndex:0];
NSString *fullPath = [NSString stringWithFormat:#"%#/%#", cache, image];
UIImage *image = [UIImage imageWithContentsOfFile:fullPath];
pathForResource:ofType: only looks in the Resources folder (and localised folders). If you are placing files into dedicated folders in the bundle then you need to use pathForResource:ofType:inDirectory: and supply the directory name.
Apple has fixed this bug on iOS8.1,Cheers
just use
NSString *fullPath = [bundle pathForResource:name ofType:#"png"];
NSData *data = [NSData dataWithContentsOfFile:fullPath];
UIImage *image = [UIImage imageWithData:data];

Can't play mp3 file in an infinite loop

I am trying to play a music file with eternal loop.
My code is:
NSString *path = [[NSBundle mainBundle] pathForResource:#"theme" ofType:#"mp3" inDirectory:#"assets/audios" ];
NSURL *url = [NSURL fileURLWithPath:path];
NSError *error;
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
audioPlayer.numberOfLoops = -1;
audioPlayer.volume = 1.0;
if (audioPlayer == nil){
NSLog(#"Error creating player: %#", error);
}
[audioPlayer prepareToPlay];
[audioPlayer play];
But it does nothing. Nothing is played and any message log is printed.
The code below works great:
NSString *path = [[NSBundle mainBundle] pathForResource:#"theme" ofType:#"mp3" inDirectory:#"assets/audios" ];
NSURL *url = [NSURL fileURLWithPath:path];
SystemSoundID soundID;
AudioServicesCreateSystemSoundID((CFURLRef)CFBridgingRetain(url), &soundID);
AudioServicesPlaySystemSound (soundID);
But I need to control the volume and the loop.
I dont know what Im doing wrong.
Can anyone help me?

Trying to add movie in xcode 4.6.1 but crash

I'm trying to add a video in xcode but it crashes: [NSURL initFileURLWithPath:]: nil string
(IBAction)Play:(id)sender {
/////
NSString *videoUrl=[[NSBundle mainBundle]pathForResource:#"tnween" ofType:#"mov"];
MPMoviePlayerController *player=[[MPMoviePlayerController alloc]initWithContentURL:[NSURL fileURLWithPath:videoUrl]];
[player play];
}
Maybe if you try:
NSString *videoUrl=[[NSBundle mainBundle]pathForResource:#"tnween" ofType:#"mov"];
NSURL *url = [NSURL urlWithString:videoUrl];
MPMoviePlayerController *player=[[MPMoviePlayerController alloc]initWithContentURL:url];

xcode cannot get sound file to play with AVAudioPlayer

I am new to iOS and trying to add sound to my app. I have followed several tutorials about adding a simple sound file to my project, but ALL with the same result. I get no errors, but no sound plays. Any ideas on what I am doing wrong? Any help would be appreciated!
- (IBAction)playSound:(id)sender {
NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:#"test" ofType:#"mp3"];
NSURL *soundFileURL = [NSURL fileURLWithPath:soundFilePath];
NSLog(soundFilePath);
NSError *error;
AVAudioPlayer *player = [[AVAudioPlayer alloc] initWithContentsOfURL:soundFileURL error:&error];
player.numberOfLoops = 1;
[player play];
}
**UPDATE***
So I never had any luck with the above code which is very discouraging, but I did end up getting it to work using the AudioToolbox Framework instead, using this:
SystemSoundID soundID;
NSString *soundFile = [[NSBundle mainBundle]
pathForResource:#"test" ofType:#"mp3"];
AudioServicesCreateSystemSoundID((__bridge CFURLRef)
[NSURL fileURLWithPath:soundFile], & soundID);
AudioServicesPlaySystemSound(soundID);
Can anyone explain to me the difference, why this one works and the other does not?? I am curious more than anything. Would love some clarification.
Finally figured it out. I needed to create a property for AVAudioPlayer in my header file in order to get it to work. Here is what I did:
// .h file
#interface ThirdViewController : UIViewController {
AVAudioPlayer *audioPlayer;
}
#property (nonatomic, retain) AVAudioPlayer *audioPlayer;
- (void) playSound //method in .m file
{
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"test"
ofType:#"mp3"]];
NSError *error;
audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:url error:&error];
[audioPlayer play];
}
Simplify your code by doing the follow. Also drop your test.mp3 to the root of your project directory in xcode. Your mp3 placement and location is very important. Also ensure volume is up, and vibrate is off of your device, and it's unmuted.
NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle]
pathForResource:#"test"
ofType:#"mp3"]];
AVAudioPlayer *audioPlayer = [[AVAudioPlayer alloc]
initWithContentsOfURL:url
error:nil];
[audioPlayer play];
Make sure you install quartz.h, or a specific framework that supports audio players. Just double check.
Had the same problem a while back and the framework must be installed properly.

UIImageView's image disappears when changing the image

When changing the image on an UIImageView in code, the image disappears. This only happens on an iPod Touch device, not on the iPhone emulator.
In my bundle I have an image named SomeImage.PNG
NSString *path = [[NSBundle mainBundle] pathForResource:#"SomeImage" ofType:#"png"];
[self.background setImage:[[UIImage alloc] initWithContentsOfFile:path]];
I must reiterate, this works fine on the iPhone simulator but not on an iPod Touch device.
Notice that the image file has an upper-case file extension, but in my code it is declared with lower case. This is the problem. So to fix the problem, change the code to this:
NSString *path = [[NSBundle mainBundle] pathForResource:#"SomeImage" ofType:#"PNG"];
[self.background setImage:[[UIImage alloc] initWithContentsOfFile:path]];
I am asking if there is a 'better' way to do what I am doing, so I don't come across such issues in the future.
Not really. Unfortunately the iOS file system is case sensitive.
Something like this.....?
NSString *filename = #"SomeImage";
NSString *extension = #"png";
UIImage *img = nil;
NSString *path = nil;
path = [[NSBundle mainBundle] pathForResource:filename ofType:[extension lowercaseString]];
img = [[UIImage alloc] initWithContentsOfFile:path];
if (img == nil) {
path = [[NSBundle mainBundle] pathForResource:filename ofType:[extension uppercaseString]];
img = [[UIImage alloc] initWithContentsOfFile:path];
}
