我最近在我的应用程序中发现了泄漏。我评论了所有的代码,并逐步摆脱了评论。这一切都导致了AVAudioRecorder。

ViewController.h:

#import <AVFoundation/AVFoundation.h>

@interface ViewController : UIViewController {
AVAudioRecorder *recorder;
}

ViewController.m:

NSURL *url = [NSURL fileURLWithPath:@"/dev/null"];

NSDictionary *settings = [NSDictionary dictionaryWithObjectsAndKeys:
                          [NSNumber numberWithFloat: 44100.0],                 AVSampleRateKey,
                          [NSNumber numberWithInt: kAudioFormatAppleLossless], AVFormatIDKey,
                          [NSNumber numberWithInt: 1],                         AVNumberOfChannelsKey,
                          [NSNumber numberWithInt: AVAudioQualityMax],         AVEncoderAudioQualityKey,
                          nil];

NSError *error;

recorder = [[AVAudioRecorder alloc] initWithURL:url settings:settings error:&error];

if (recorder) {
    [recorder prepareToRecord];
    recorder.meteringEnabled = YES;
    [recorder record];
}

抱歉小图片。内存泄漏只有16个字节,我无法追溯到代码,因为它不允许我这样我只是使用了评论策略。每当退出视图控制器时都会使用[recorder stop];

任何想法?
