Ios UIPopover从错误的按钮显示

我有一个应用程序，可以从现有库中获取图像，也可以从相机中获取新图像

在iPad上，当我按下“从库”按钮时，弹出框会（正确地）显示在按下按钮的上方，但是当我按下相机按钮的“拍照”时，相机控制器也会显示在“从库”按钮上方。。。我需要这个出现在“拍照”按钮上，否则它看起来有点奇怪

这里是使用的代码

- (void)pickImageFromLibrary: (id)sender
{
    [Flurry logEvent: @"PickImage"];

    [self openImagePickerWithSourceType: UIImagePickerControllerSourceTypePhotoLibrary];

}


- (void)takePicture: (id)sender
{
    [Flurry logEvent: @"TakeImage"];

    [self openImagePickerWithSourceType: UIImagePickerControllerSourceTypeCamera];

}

- (void)openImagePickerWithSourceType: (UIImagePickerControllerSourceType)sourceType
{
    if ( ![UIImagePickerController isSourceTypeAvailable: sourceType] ) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle: NSLocalizedString( @"Error", @"" )
                                                        message: NSLocalizedString( @"We are sorry, but this functionality is not available at your device.", @"No camera eror" )
                                                       delegate: nil
                                              cancelButtonTitle: NSLocalizedString( @"Dismiss", @"")
                                              otherButtonTitles: nil];
        [alert show];
        return;
    }
    UIImagePickerController *picker = [[UIImagePickerController alloc] init];
    picker.delegate = self;
    picker.sourceType = sourceType;
    self.isCameraShown = YES;


    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) {
       self.popover = [[UIPopoverController alloc] initWithContentViewController:(UIViewController *)picker];
        CGRect takePhotoRect;
        takePhotoRect.origin = self.view.frame.origin;
        takePhotoRect.size.width = 1;
        takePhotoRect.size.height = 1;
        [self.popover setPopoverContentSize:CGSizeMake(320.0, 216.0)];

        [self.popover presentPopoverFromRect:_openLibraryButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

    }else{
        [self presentViewController:picker animated:YES completion:NULL ];
    }


}

您正在从

openLibraryButton

显示popover

[self.popover presentPopoverFromRect:_openLibraryButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

您需要添加检查以查看是否按下了

拍照

或

从库中选择

按钮，然后显示该按钮的弹出框

SUDO代码：

if (sourceType == UIImagePickerControllerSourceTypePhotoLibrary) {
    [self.popover presentPopoverFromRect:_openLibraryButton.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
} else {
    [self.popover presentPopoverFromRect:_takeFromCamera.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
}

看起来您正在强制它始终使用库中的

frame
[self.popover presentpopoverfromrrect:_openLibraryButton.frame-inView:self.view-permittedrowdirections:uipoperrowdirection任何动画：YES]侧注-不要在弹出式沙发中显示相机。只为照片库使用popover。嗨，机器人，我如何添加检查部分？你有我可以使用的例子吗？@DaveBradford你可以检查你在内部传递的源类型-工作完美，非常感谢！标记为已接受！
