解雇图像选择器导致崩溃

Question

我使用un UINavigationCtronller从UIViewController导航到一个UIViewController B. 在UIViewController B的视图中，我点击一个按钮并调用UIImagePicker

UIImagePickerController *ipc = [[UIImagePickerController alloc] init];

ipc.sourceType = UIImagePickerControllerSourceTypeCamera;

ipc.delegate = self;

ipc.allowsEditing = NO;

[self presentModalViewController:ipc animated:YES];

如果点击UIImagePicker的“取消”按钮，我会调用

-(void)imagePickerControllerDidCancel:(UIImagePickerController*)picker{



[picker dismissModalViewControllerAnimated:YES];

}

UI将返回UIViewController A而不是B

如果我点击任何地方，应用程序崩溃了。

欢迎任何评论

Answer 1

而不是

[picker dismissModalViewControllerAnimated:YES];

试

[picker.presentingViewController dismissModalViewControllerAnimated:YES];

您希望呈现选择器的ViewController被解雇，而不是选择器本身。
