我是iphone开发的新手(Xcode中的第4天),我正在尝试使用AwesomeMenu库实现AvAudioPlayer并控制它。我没有初始化和播放音频的问题,但是当我尝试通过令人敬畏的菜单控件暂停或停止音频时,AVAudioPlayer没有响应。非常感谢任何帮助。
修改
我能够确定我的方法没有在其中执行条件if / else语句。这更令人费解。 didSelectIndex正在触发,但其中的if语句不是。我正确编写条件语句吗?
我的代码:
AVPlayerItem *playerItem = [AVPlayerItem playerItemWithURL:url];
podcastPlayer = [[AVPlayer playerWithPlayerItem:playerItem] retain];
[podcastPlayer play];
//Control for AvAudioPlayer
- (void)AwesomeMenu:(AwesomeMenu *)menu didSelectIndex:(NSInteger)idx{
if (idx==0) {
if(!podcastPlayer.isPlaying){
podcastPlayer.play;
}
}else if(idx==1){
if(podcastPlayer.isPlaying){
podcastPlayer.pause;
}
}else if(idx==2){
if(podcastPlayer.isPlaying){
podcastPlayer.stop;
podcastPlayer.release;
GSCCAppDelegate *appDelegate = (GSCCAppDelegate *)[[UIApplication sharedApplication] delegate];
[appDelegate.menu removeFromSuperview];
}
}else if(idx==3){
}else if(idx==4){
}else if(idx==5){
}
NSLog(@"Select the index : %d",idx);
}
修改
- (void)AwesomeMenu:(AwesomeMenu *)menu didSelectIndex:(NSInteger)idx{
if (idx==0) {
NSLog(@"Index 0"); //Doesn't work
}else if(idx==1){
NSLog(@"Index 1"); //Doesn't work
}
}
NSLog(@"Select the index : %d",idx); //<--This Works.
}
答案 0 :(得分:0)
将AVPlayerItem *playerItem
声明为property
和synthesis
。
不要声明为本地
