使用PhotoLibrary作为源时,UIImagePickerController崩溃

Question

我正在使用xcode 5.1并在ios7.1和7.0.2上测试了代码.该应用程序在设备上的两种情况下与UIImagePickerController崩溃:

1)当allowsEditing设置为YES时,在我裁剪图片并按"选择"后,一旦它返回到我自己的视图,应用程序崩溃

2)在里面UIImagePickerController,当我从照片列表返回到相册列表并且我在照片列表的底部时,它崩溃了(无论allowsEditing是否是).请注意,如果我滚动照片列表,它不会崩溃.

这是我的代码:

- (IBAction)photoPickPressed:(id)sender {

    if ([self isPhotoLibraryAvailable]) {

        self.imagePicker = [[UIImagePickerController alloc] init];
        self.imagePicker.delegate = self;
        self.imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
        self.imagePicker.allowsEditing = YES;
        NSString *requiredMediaType = (__bridge NSString*)kUTTypeImage;
        self.imagePicker.mediaTypes = [[NSArray alloc] initWithObjects:requiredMediaType, nil];
        [self presentViewController:self.imagePicker animated:YES completion:nil];
    }
}

#pragma mark - image picker delegates
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info{
    [picker dismissViewControllerAnimated:YES completion:^(){
        NSLog(@"finished image picking");
    });
}

- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker{
    [picker dismissViewControllerAnimated:YES completion:nil];
}

崩溃消息是

*由于未捕获的异常'NSInvalidArgumentException'终止应用程序,原因:'* - [NSProxy doesNotRecognizeSelector:scrollViewDidScroll:]调用!'

注意:即使我设置为YES,如果我使用相机也不会崩溃allowsEditing.它也只能在真实设备上崩溃,而不是在模拟器上崩溃.

只是为了澄清(也许是不相关的),最初我将imagePicker声明为

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

,它崩溃了.所以我搜索了很多,并且帖子说控制器可能被回收,并建议在类定义中声明它.所以现在我在我的班级声明中宣布:

@property (strong, nonatomic) UIImagePickerController *imagePicker;

提前致谢.

更新:我甚至试图将imagePickerController的调用放到我的应用程序的根视图中,它仍然会崩溃同样的消息.我不应该加载任何可滚动的视图.

Answer 1

经过几个小时的调查和试用，我确认这是由集成到应用程序的第三方框架引起的：UIImagePickerController如果我链接该框架，即使那个空应用程序也会崩溃。

感谢您的帮助！
