Ios 内存泄漏UIStatusBarHideAnimationParameters

我在XCode中运行仪器并使用“泄漏”。在关闭

UIImagePickerController

后，我收到一个泄漏的对象

在详细信息面板中，我看到泄漏的对象为

UIStatusBarHideAnimationParameters

我不明白这是从哪里来的。以下是我的密码-

- (void) imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
    // Handles when the image has been picked
    NSString *mediaType = [info objectForKey: UIImagePickerControllerMediaType];
    UIImage *originalImage, *editedImage, *imageToSave;
    BOOL dismissed = NO;

    [_activityIndicator show];

    if (CFStringCompare((CFStringRef) mediaType, kUTTypeImage, 0) == kCFCompareEqualTo) {
        editedImage = (UIImage *) [info objectForKey:UIImagePickerControllerEditedImage];
        originalImage = (UIImage *) [info objectForKey:UIImagePickerControllerOriginalImage];

        if (editedImage) {
            imageToSave = editedImage;
        } else {
            imageToSave = originalImage;
        }

        NSData *imageData = UIImageJPEGRepresentation(imageToSave, 0.1);
        imageToSave = [UIImage imageWithData:imageData];

        // Display the image in the image view
        [self displayImageInImageView:imageToSave];

        [picker dismissViewControllerAnimated:YES completion:^{
            [_activityIndicator show];
            [self uploadPhotoToS3SyncWithImage:imageToSave];
            [NSThread sleepForTimeInterval:1.5];
            [_nextButton setEnabled:YES];
            [_uploadPhotoButton setTitle:@"Upload Another" forState:UIControlStateNormal];
            [self performSegueWithIdentifier:RIDEPhotoUploadToSetLocationSegue sender:self];
        }];

        dismissed = YES;
    }

    if (!dismissed) {
        [picker dismissViewControllerAnimated:YES completion:nil];
    }
}

当我单击扩展详细信息面板中的堆栈跟踪时，XCode突出显示了行

discomered=YES

。但AFAIK

BOOL

变量不必取消分配。也没有带ARC的拾取器

我遗漏了什么？

也许您需要清除UIImagePickerController的代理？委托可以阻止对象被正确释放。是的，似乎就是这样。我将选择器的委托设置为nil，我不再看到这个特定的内存泄漏。谢谢。
