Question

我面临着一个与UITextField的Autocorrection相关的奇怪和奇怪的问题。我有一个派生自UIScrollView（来自UIScrollView的子类）的类，包含一些textfield，textview＆amp;分别位于底部的按钮。

我在textfield＆amp;中输入一些文字时遇到问题自动修正泡沫弹出。如果我点击气泡来辞职＆amp;点击提供弹出窗口的按钮，它的尺寸正确。但是，如果我不禁用气泡并向上滚动视图以点击按钮，它会弹出错误的位置。

这就是我为呈现popover而做的事情：

- (void)presentImagePicker:(UIImagePickerControllerSourceType)type
             withAnimation:(BOOL)animated {
  if ([popoverViewController_ isPopoverVisible]) {
    [popoverViewController_ dismissPopoverAnimated:YES];
    return;
  }

  UIImagePickerController *picker =
      [[[UIImagePickerController alloc] init] autorelease];
  [picker setDelegate:self];
  [picker setSourceType:type];
  [[picker navigationBar] setTintColor:[UIColor bloggerBarColor]];
  UIPopoverController *popoverController =
      [self popoverWithViewController:picker];
  CGRect rect = CGRectZero;

  if (type == UIImagePickerControllerSourceTypePhotoLibrary) {
    rect = [[composeView_ addPhotoLibraryButton] frame];
  } else {
    rect = [[composeView_ addPhotoCameraButton] frame];
  }

  [popoverController presentPopoverFromRect:rect
                                     inView:[self view]
                   permittedArrowDirections:UIPopoverArrowDirectionAny
                                   animated:YES];
}
