[Object removeFromSuperview];
}
}
[m_toolbarImage setFrame:CGRectMake(0, 427, 320, 55)];
[cameraSelectedButton setFrame:CGRectMake(128, 432, 86, 44)];
[m_cancelButton setFrame:CGRectMake(10, 434, 82, 40)];
[m_cancelButton setTitle:@"Close" forState:UIControlStateNormal];
[m_cancelButton setBackgroundImage:[UIImage imageNamed:@"menu-bar-button.png"] forState:UIControlStateNormal];
[m_cancelButton setTitleColor:[UIColor colorWithRed:110/256.0 green:52/256.0 blue:28/256.0 alpha:1.0] forState:UIControlStateNormal];
[cancelButton setFrame:CGRectMake(120, 434, 35, 35)];
[selectButton setFrame:CGRectMake(184, 434, 35, 35)];
}
推荐答案
这似乎无论是否使用ARC,iOS 5中的UIImagePickerController都会出现问题。
This seems to be a problem with UIImagePickerController in iOS 5 whether using ARC or not.
我有一个使用xcode 3.2.5为iOS 4开发的应用程序,当从图书馆拍摄或选择照片时,仪器显示没有泄漏(在运行的设备上测试) iOS 4.1)。在运行iOS 5.1的设备上测试的相同代码如上所述泄漏。
I have an app developed for iOS 4 using xcode 3.2.5 and Instruments shows no leaks when a photo is either taken or selected from the library (tested on a device running iOS 4.1). The same code tested on a device running iOS 5.1 leaks as described.
我知道这不是一个答案,但问题似乎比原始问题更广泛。
I know this isn't an answer but the problem seems broader than the original question.
