UISearchDisplayDelegate如何删除这个不透明的视图？ [英] UISearchDisplayDelegate how to remove this opaque view?

问题描述

如何从 UISearchDisplayController 以编程方式显示/隐藏此不透明视图？

可能在 searchDisplayControllerWillBeginSearch 或 searchDisplayControllerDidBeginSearch 我需要设置一些东西......但是什么？

谢谢。

使用 UIKeyboardWillAppearNotification 。

  [[NSNotificationCenter defaultCenter] addObserver：self selector：@selector（keyboardWillShow）name：UIKeyboardWillShowNotification object：nil]; 
  

OpaqueView是 UIControl ，alpha = 0.8。

   - （void）keyboardWillShow {
 for（UIView * subview in self.view.subviews）{
 if（[subview] isKindOfClass：[UIControl class]]）{
 UIControl * v =（UIControl *）subview; 
 if（v.alpha< 1）{
 v.hidden = YES; 
} 
} 
} 
} 
  

I使用这种 ORRIBLE方式临时修复问题....任何其他想法将不胜感激！

谢谢。

how can i programmatically show/hide this opaque view from UISearchDisplayController?

Probably in searchDisplayControllerWillBeginSearch or searchDisplayControllerDidBeginSearch i need to set something... but what?

thanks.

解决方案

Temporary solved using UIKeyboardWillAppearNotification.

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow) name:UIKeyboardWillShowNotification object:nil];

OpaqueView is an UIControl with alpha = 0.8.

- (void) keyboardWillShow {
  for( UIView *subview in self.view.subviews ) {
   if( [subview isKindOfClass:[UIControl class]] ) {
      UIControl *v = (UIControl*)subview;
      if (v.alpha < 1) {
        v.hidden = YES;
      }
    }
  }
}

I used this ORRIBLE way to temporary fix problem.... any other idea will be appreciated!

thanks.
