Question

我在XCode中运行Instruments并使用＆＃39; Leaks＆＃39;。我在解雇UIImagePickerController后得到一个泄露的物体。

在详情面板中，我将泄露的对象视为UIStatusBarHideAnimationParameters。

我无法理解这是从哪里来的。以下是我的代码 -

- (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];
    }
}

当我在扩展详细信息面板中单击堆栈跟踪时，XCode突出显示行dismissed = YES。但是AFAIK BOOL变量不必解除分配。 picker也没有ARC。

我在这里缺少什么？
