[英]My Application crashes when playing a sound
我試圖單擊一個按鈕來播放聲音。 但是,當我運行該應用程序時,它崩潰了,我得到Thread 1 : signal SIGABRT
。
這是我的代碼:
.h文件
#import <AVFoundation/AVFoundation.h>
@interface HljodViewController : UIViewController <AVAudioPlayerDelegate>{
}
-(IBAction)playsound;
.m文件
-(IBAction)playsound {
NSString *path = [[NSBundle mainBundle] pathForResource:@"Geese_4" ofType:@"mp3"];
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.numberOfLoops = 1;
[theAudio play];
}
如果您不捕獲NSError
沒人能告訴您如何解決您的問題。 我建議您執行以下操作:
NSError *outError = nil;
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:&outError];
if (outError)
{
NSLog(@"%@", [outError localizedDescription]);
}
... // continue on to happy time
嘗試這個:
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlayback error:nil];
[[AVAudioSession sharedInstance] setActive:YES error:nil];
NSString *path = [[NSBundle mainBundle] pathForResource:@"yourfile" ofType:@"mp3"];
NSError *error;
AVAudioPlayer *sound = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:&error];
[sound play];
