objective-c - 我收到错误消息，“从不兼容的类型“gameViewController”分配给“id avaudioplayerdelegate””

Question

    -(void)playSound: (NSString*)sound 

{
NSString *path = [[NSBundle mainBundle] pathForResource:sound ofType:@"mp3"];

    AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate = self; 
    [theAudio play];
    [AVAudioPlayer release];
}

一切仍然有效，只是一个恼人的错误可能会导致延迟。

Answer 1

确保gameViewController符合AVAudioPlayerDelegate协议：

@interface gameViewController : NSObject <AVAudioPlayerDelegate>
.
.
.
@end

假设那是你班级的名字。
