我正在制作一个简单的音板应用程序,无论何时按下按钮,它都会播放相应的声音。但是,我似乎没有正确地释放我的变量(或者现在真的没有,因为我将我的代码恢复到播放声音但工作内存泄漏的地方)并且我知道它不符合app store标准。我需要弄清楚如何解决这个问题,所以任何帮助都表示赞赏!
我的ViewController.h是:
#import <UIKit/UIKit.h>
#import <Foundation/Foundation.h>
#import <AVFoundation/AVAudioPlayer.h>
@interface FirstViewController : UIViewController <AVAudioPlayerDelegate>

我尝试在各种推送方法(pushTropical,pushBurnHouse等)中发布'theAudio'变量,就像这样......
-(IBAction)pushExcited {
NSString *path = [[NSBundle mainBundle]
pathForResource:@"dukesIsExcited" ofType:@"m4a"];
AVAudioPlayer* theAudio = [[AVAudioPlayer alloc] initWithContentsOfURL:[NSURL fileURLWithPath:path] error:NULL];
theAudio.delegate = self;
[theAudio play];
[theAudio release];
}
......然而,声音完全拒绝播放。所以我很茫然,因为无论何时我尝试在任何地方发布'theAudio',但在这些功能内部它都不会识别它以释放它。救命啊!
答案 0 :(得分:3)
在将类设置为委托后,您应该通过audioPlayerDidFinishPlaying:successfully:
AVAudioPlayerDelegate方法释放AVAudioPlayer。
即:
- (void)audioPlayerDidFinishPlaying:(AVAudioPlayer *)player successfully:(BOOL)flag {
[player release];
}
一旦你完成了这一切,一切都会好起来的。
