iphone - iOS 5 中 UIImagePickerController 出现内存警告，但 ios 4.x 中没有

Question

这似乎是 iOS 5 中 UIImagePickerController 的问题。

我开发了一个 xcode4.3 的应用程序，我在两部 iPhone(iOS 4.3 和 5.1)上测试了它

{

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
            imagePicker.delegate = self;
            imagePicker.view.tag = tag;
            imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
            if ( imagePicker.view.tag == 1) 
            { //Editing doent allowed for biz card
                  imagePicker.allowsEditing = YES;
                  [Flurry logEvent:@"Edit Contacts:Attempt to add an image for the Contact picture using the camera"];
            }
            else {
                  [Flurry logEvent:@"Edit Contacts:Attempt to add an image for the Business Card picture using the camera"];
            }
            [self presentModalViewController:imagePicker animated:YES];
            [imagePicker release];

}

如果设备是 iOS 4.1

拍摄照片或从库中选择照片时没有泄漏/没有内存警告(在运行 iOS 4.1 的设备上测试)。

在运行 iOS 5.1 的设备上测试相同的代码时，当从相机捕获中拍摄照片时，我经常遇到 1 级内存警告。

你..？以及如何解决这个问题..？

试试这个并检查:

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
   [picker dismissModalViewControllerAnimated:YES];
}

添加此方法并检查。

也像这样添加并检查:

UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
            imagePicker.delegate = self;
            imagePicker.view.tag = tag;
            imagePicker.sourceType = UIImagePickerControllerSourceTypeCamera;
            if ( imagePicker.view.tag == 1) 
            { //Editing doent allowed for biz card
                  imagePicker.allowsEditing = YES;
                  [Flurry logEvent:@"Edit Contacts:Attempt to add an image for the Contact picture using the camera"];
            }
            else {
                  [Flurry logEvent:@"Edit Contacts:Attempt to add an image for the Business Card picture using the camera"];
            }
            [self presentViewController:imagePicker animated:YES completion:nil];
