在Xcode的Storyboard模式中。使用导航控制器时,会自动显示后退按钮。
通常,为了播放我的声音,我会从选择器或动作中调用我的任务。
如何使用后退按钮播放此声音?如何对此进行编码,因为后退按钮会自动显示在我的视图中?
- (void)myTask {
NSString* resourcePath = [[NSBundle mainBundle] resourcePath];
resourcePath = [resourcePath stringByAppendingString:@"/pop.wav"];
NSLog(@"Path to play: %@", resourcePath);
NSError* err;
//Initialize our player pointing to the path to our resource
player = [[AVAudioPlayer alloc] initWithContentsOfURL:
[NSURL fileURLWithPath:resourcePath] error:&err];
if( err ){
//bail!
NSLog(@"Failed with reason: %@", [err localizedDescription]);
}
else{
//set our delegate and begin playback
player.delegate = self;
[player play];
}
}

您可以在- (void)viewWillDisappear:(BOOL)animated { // in here }
