Possible Duplicate:
UIPopovercontroller dealloc reached while popover is still visible
我正在创建一个通用应用程序并尝试从相机胶卷中选择一张图片。在 iPhone 上工作正常，iPad 需要一个弹出窗口，所以已经这样做了，现在不断出现错误
-[UIPopoverController dealloc] 在 popover 仍然可见时到达。
我研究过:
和谷歌，没有什么能解决这个问题
卡住了，感谢任何建议
我在 .h 中实现了 popover 委托(delegate)
.m
- (void)logoButtonPressed:(id)sender /////////////iPad requires seperate method ////////////////
{
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
LogCmd();
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
////////
imagePicker.modalPresentationStyle = UIModalPresentationCurrentContext;
////////
[self presentModalViewController:imagePicker animated:YES];
}
else
{
// We are using an iPad
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
imagePickerController.delegate = self;
UIPopoverController *popoverController=[[UIPopoverController alloc] initWithContentViewController:imagePickerController];
popoverController.delegate=self;
[popoverController presentPopoverFromRect:((UIButton *)sender).bounds inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}
}
我现在也试过这个:
.h
@property (strong) UIPopoverController *pop;
.m
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) { ///code added
LogCmd();
UIImagePickerController *imagePicker = [[UIImagePickerController alloc] init];
imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
imagePicker.delegate = self;
imagePicker.allowsEditing = YES;
[self presentModalViewController:imagePicker animated:YES];
///code added////////////////////////////
}
else {
if (self.pop) {
[self.pop dismissPopoverAnimated:YES];
}
// If usingiPad
UIImagePickerController *imagePickerController = [[UIImagePickerController alloc] init];
UIPopoverController *popoverController=[[UIPopoverController alloc] initWithContentViewController:imagePickerController];
[popoverController presentPopoverFromRect:((UIButton *)sender).bounds inView:sender permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
