如何在下面的代码中释放AVAudioPlayer
|
我想释放为AVAudioPlayer分配的内存，但是当我尝试释放它时，声音却没有播放，这是潜在的内存泄漏，我该如何解决。
在这里，当选择错误时使用下面的代码，然后我播放错误声音，如果我选择了多次错误选择，那么它被分配了多次，那么我该如何摆脱这种情况。
else
{
NSString *soundName=@\"Error.mp3\";
NSError *error;
NSURL *urlString = [NSURL fileURLWithPath:[NSString stringWithFormat:@\"%@/%s\", [[NSBundle mainBundle] resourcePath],[soundName UTF8String]]];
AVAudioPlayer *worngAudioPlay = [[AVAudioPlayer alloc] initWithContentsOfURL:urlString error:&error];// here I also used to release using autorelease then not played sound
worngAudioPlay.delegate = self;
if (worngAudioPlay == nil)
{
}
else
{
[worngAudioPlay play];
}
// [worngAudioPlay release]; // Here I released then not played sound
}
没有找到相关结果

在您的实现（.m）文件中：在上面的代码中：else { NSString *soundName=@\"Error.mp3\"; NSError *error; NSURL *urlString = [NSURL fileURLWithPath:[NSString stringWithFormat:@\"%@/%s\", [[NSBundle mainBundle] resourcePath],[soundName UTF8String]]]; AVAudioPlayer *worngAudioPlay = [[AVAudioPlayer alloc] initWithContentsOfURL:urlString error:&error]; if (worngAudioPlay != nil) { // this will cause the previous one to be released [self setPlayer:worngAudioPlay]; [worngAudioPlay release]; worngAudioPlay.delegate = self; [worngAudioPlay play]; } }-(void)dealloc { [player release]; [super dealloc]; }
