我正在开发一款可让用户从自己的相册中选择图片的应用。它适用于iPhone,但不适用于iPad。
I am working on an app that lets the user select images from his own photo album. It works on iPhone, but not on iPad.
我做了一个 UIPopoverController ,一切正常,用户可以选择一张照片,但是当用户按USE按钮。应用程序兑现了一个说法
I made a UIPopoverController, and it all works fine, the user can pick a photo, but when the user pushes "USE" button. the app cashes a says
UIPopoverController dealloc]当popover仍然可见时
UIPopoverController dealloc] reached while popover is still visible
这里是代码:
- (void)choosePhotoFromLibraryipad:(id)sender{ if(![popoverController isPopoverVisible]){ imagePicker = [[UIImagePickerController alloc] init]; imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary; imagePicker.delegate = self; imagePicker.allowsEditing = YES; self.popoverController = [[UIPopoverController alloc] initWithContentViewController:imagePicker]; [self.popoverController presentPopoverFromRect:CGRectMake(0.0, 0.0, 400.0, 400.0) inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES ]; } }推荐答案
检查 .h 文件。确保 popoverController 的 @property 为 strong 而不是弱 。一个小时的时间浪费在这样的简单事情上。
Check your .h file. Make sure that your @property for your popoverController is strong instead of weak. Many an hour of time has been wasted over simple things like this.
