  iPhone应用中,添加subView到窗口,还要实现一个功能,在点击关闭按钮是,应该subView隐藏起来,这是创建subView的代码:
  UIView*subView=[[UIView alloc]initWithFrame:CGRectMake(0,0, 1024,768)];
  subView.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:@"bgPopupback.png"]];
  UIWindow* window = [UIApplication sharedApplication].keyWindow;
  if (!window)
  window = [[UIApplication sharedApplication].windows objectAtIndex:0];
  [[[window subviews] objectAtIndex:0] addSubview:subView];
  关闭按钮:
  -(void)closeButtonAction{
  NSLog(@"CLicked on this button");
  [subView removeFromSuperview] ;
  self.tableView.userInteractionEnabled=TRUE;
  
  }

  解决方法 :
  使用removefromsuperview删除subView,如果只是想隐藏 subView.hidden = YES;,在按钮动作内执行。
