我正在设法为我的应用添加背景音,我把源代码
-(IBAction)play
{
NSString *soundFilePath =[[NSBundle mainBundle] pathForResource: @"larga"ofType: @"mp3"];
NSURL *fileURL = [[NSURL alloc] initFileURLWithPath: soundFilePath];
AVAudioPlayer *newPlayer =[[AVAudioPlayer alloc] initWithContentsOfURL: fileURL error: Nil];
self.player = newPlayer;
[self.player prepareToPlay];
[self.player setDelegate: self];
[self.player play];
[NSTimer scheduledTimerWithTimeInterval: 30 target: self
selector: @selector(play:) userInfo: nil repeats: YES];
}
- (void)viewDidLoad
{
[super viewDidLoad];
.............................
...............................
[self.player play];
}
答案 0 :(得分:9)
有了这个:
[NSTimer scheduledTimerWithTimeInterval: 30 target: self
selector: @selector(play:) userInfo: nil repeats: YES];
您正在视图控制器上调用方法播放,该方法不存在。
尝试创建它(删除:from play:在选择器中):
[NSTimer scheduledTimerWithTimeInterval: 30 target: self
selector: @selector(play) userInfo: nil repeats: YES];
-(void)play
{
[self.player play];
}
