Question

可能重复：
thread 1 program received signal SIGABRT

#import <UIKit/UIKit.h>

int main(int argc, char *argv[]) {

    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    int retVal = UIApplicationMain(argc, argv, nil, nil);
    [pool release];
    return retVal;
}

当我在我的设备上运行时，它给我一个错误

2011-11-10 14:59:43.487 AVMultiPlayer[13554:707] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:]: nil string parameter'

terminate called throwing an exception(gdb)

这是它发送的输出代码

0x0000222c  <+0060>  str    r0, [sp, #4] <------ Thread 1:Program received signal: "SIGABRT".

这是它给我的错误

- (void)playOnce:(NSString *)aSound {

        NSString *path = [[NSBundle mainBundle] pathForResource:aSound ofType:@"caf"];
        AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
        [theAudio setDelegate: self];
        [theAudio setNumberOfLoops:0];
        [theAudio setVolume:1.0];
        [theAudio play];
    [path retainCount];




}

- (void)playLooped:(NSString *)aSound {

        NSString *path = [[NSBundle mainBundle] pathForResource:aSound ofType:@"caf"];
        AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
        [theAudio setDelegate: self];
        // loop indefinitely
        [theAudio setNumberOfLoops:-1];
        [theAudio setVolume:1.0];
        [theAudio play];
    [theAudio release];


}

我如何解决这个问题它在模拟器上运行没有任何问题，但是当我在我的设备上尝试它时，它给我一个错误我的程序有4个视图，其他3个工作完美除了最后一个我的程序只是按钮那个发声
