UIPopoverController：当弹出窗口仍然可见时达到dealloc [英] UIPopoverController: dealloc reached while popover is still visible

问题描述

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.
