使用UIImagePickerController出现内存泄漏的问题

Question

今天公司的app一点开就闪退，于是就查了内存泄漏的问题，用Instruments 发现选择照片后没多久就出现UIStatusBarHideAnimationParameters这个问题，本来还以为是状态栏的事，后来网上查了点资料，说是UIImagePickerController的问题，想请问一下怎么解决？
试过了在didFinishPickingMediaWithInfo 方法里把imagepicker的代理设为nil，
但还是不行

代码：

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
    if ([self.mutiImageSelector.imgArr count] < 3) {
        UIImage *img = [info objectForKey:UIImagePickerControllerOriginalImage];
        //生成缩略图
      UIImage *thumbNail =  [self createThumbnailWithSourceImge:img andNewSize:self.mutiImgSelectorImgViewSize];
        [self.mutiImageSelector.thumbNailArr addObject:thumbNail];
        [self.mutiImageSelector.imgArr addObject:img];
        [self.mutiImageSelector.imgTabelView reloadData];
        //保存拍照的照片到相册
        if (self.takePicBtn.state == 1) {
             UIImageWriteToSavedPhotosAlbum(img, self, nil, NULL);
        }
        picker.delegate = nil;
        [self.myImgPickerController dismissViewControllerAnimated:YES completion:nil];
    }else if ([self.mutiImageSelector.imgArr count] >= 3){
        UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:@"error" message:@"最多只能上传3张图片" delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
        [alertView show];
    }
}

你能确认是UIImagePickerController的内存泄露，还是你用到的其他方法有内存泄露吗？
