Question

页: 1 姓名为Mainview Controller,其中一米从事AVAudioer的所有行动。

档案中

@class MainViewController;

@protocol MainViewControllerDelegate 

-(void)audioPlayerBeginInterruption:(AVAudioPlayer *)audioPlayer;

-(void)audioPlayerEndInterruption:(AVAudioPlayer *)audioPlayer;

@end

@interface MainViewController : UIViewController <UIActionSheetDelegate, InfoDelegate, AVAudioPlayerDelegate>

在上述发言中,我被混为一谈,一米应做AVAudioPlayerDelegate或。

如果是的话,@protocolAVAudioPlayerDelegate 然后是 黄色植被警报,称AVAudioPlayer的重复议定书定义被忽视。

如果没有界定@protocolAVAudioPlayer,则在其他任何地方。

另一混淆 i 本应在案卷中宣布这些方法,但先在案卷中执行。

-(void)audioPlayerBeginInterruption:(AVAudioPlayer *)audioPlayer; -(void)audioPlayerEndInterruption:(AVAudioPlayer *)audioPlayer;

请提供帮助。

我认为,你正在这里错误地使用@protocol建筑。你们可以走下去,放弃整个@protocol块,并公正执行你们的班子。仅需要打上你的班子,就象AVAudioPlayer这样的一个例子:

@interface MainViewController : UIViewController <UIActionSheetDelegate, InfoDelegate, AVAudioPlayerDelegate>

接着,当你看一看你的AVAudio The PLayer Object, to ensure the MainViewController as the delegation:

audioPlayInstance.delegate = self;

Lastly, implement the two methods you want to be called on your AVAudioPlayer instance (I called it audioPlayInstance above). You only need to put these in your .m file, NOT you header. The header declaration for these methods is handled by the AVAudioPlayer.h class file.

Good Luck!
