ios - GestureRecognizer 干扰 w/MapKit 弹出窗口

Question

我有一个在 iOS 中运行良好的简单 MapKit 应用程序。它有注释，当用户点击它们时，会显示带有标题/副标题的小灰色默认弹出窗口。我什至在其中添加了一个 UIButton View 。

所以问题是，我的 map 上方有一个搜索栏。每当用户单击 MapView 时，我都想从搜索框中退出 FirstResponder，因此我添加了一个简单的点击手势响应程序。工作得很好，除了现在不再显示小的灰色细节弹出窗口(只有注释图钉)!我仍然可以点击、缩放、四处移动等。只是没有弹出窗口。

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(tapped:)];
tap.cancelsTouchesInView = NO;
tap.delaysTouchesBegan = NO;
tap.delaysTouchesEnded = NO;
[mapView addGestureRecognizer:tap];


-(IBAction)tapped:(UITapGestureRecognizer *)geture {
    [searchBar resignFirstResponder];
}

是否可以两全其美？

Answer 1

我使用了一个类似于下面的委托(delegate)方法来在应该转到我的自定义 View 的平移手势识别器的触摸和应该转到包含我的自定义 View 的 ScrollView 的触摸之间进行仲裁。类似的东西可能对您有用。

// the following UIGestureRecognizerDelegate method returns YES by default.
// we modify it so that the tap gesture recognizer only returns YES if
// the search bar is first responder; otherwise it returns NO.
- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch
{
  if ((gestureRecognizer == self.tapGestureRecognizer) &&
      (gestureRecognizer.view == self.mapView) &&
      [searchBar isFirstResponder])
  {
    return YES;  // return YES so that the tapGestureRecognizer can deal with the tap and resign first responder
  }
  else
  {
    return NO;  // return NO so that the touch is sent up the responder chain for the map view to deal with it
  }
}
