iphone - 在 iPhone 上打开模态视图并关闭

Question

如何显示全屏模态视图，然后如果用户触摸 View 上的任何位置， View 将自行删除。

Answer 1

你可以呈现一个模态视图，它有一个自定义按钮作为背景，然后当你按下按钮或“背景”时，你可以调用[self dismissModalViewControllerAnimated:YES];

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event 
{
   UITouch *touch = [touches anyObject];

 if ([touch view] == self) {
      if ([touch tapCount] == 2) {
         /* 2 touches here, you can dismiss your view */
      }
    }
}

- (void)touchesEnded:(NSSet *)touches withEvent:(UIEvent *)event
{
   UITouch *touch = [touches anyObject];

   if ([touch view] == self) {
      if ([touch tapCount] == 1) {
  /* 1 touch, dismiss your view */   
  }
}
