Question

我想在rightcalloutaccessoryview按钮上添加新视图。我目前有在地图上删除图钉的功能。点击引脚时，标题，副标题和V形符号的标注（MKAnnotation）会加载。当我点击雪佛龙（rightcalloutaccessoryview）时，我希望弹出另一个视图，显示更多信息。现在，雪佛龙水龙头什么也没做。这就是我所拥有的：

-(IBAction)showInfo:(id)sender 
{     
     int calloutButtonPressed = ((UIButton *)sender).tag;
     if(calloutButtonPressed < 99999)
     {
          if(self.DetailView == nil)
          {
               DetailViewController *tmpViewController = [[UIViewController alloc] initWithNibName:@"DetailView" bundle:nil];
               self.DetailView = tmpViewController;
               [tmpViewController release];
          }

          if (calloutButtonPressed == 1) 
          {
                         // Using the debugger, I found that calloutButtonPressed is equal to 0 when the button is pressed.
                         // So I'm not sure what the point of this method is...
                }
          self.DetailView.title = @"Title";
     }
 }

我已经确认按下V形符号时会调用此动作方法。不幸的是，我无法得到它来提出一个新观点。如果有人知道我做错了什么，请告诉我。我有点紧张......

谢谢！

    -(IBAction)showInfo:(id)sender 
{   
     int calloutButtonPressed = ((UIButton *)sender).tag;
     if(calloutButtonPressed < 99999)
     {
          if(self.detailView == nil)
          {
               DetailViewController *tmpViewController = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:nil];
               self.detailView = tmpViewController;
               [tmpViewController release];
          }

          [self.navigationController pushViewController:self.detailView animated:YES];

          if (calloutButtonPressed == 0) 
          {
               // TRP - I inserted my view atIndex:99999 to ensure that it gets placed in front of all windows
               // TODO: figure a better way to do this
               [self.view insertSubview:detailView.view atIndex:99999];
          }
          self.detailView.title = @"Title";
     }

}

缺少这一陈述：

[self.view insertSubview:detailView.view atIndex:99999];

我想找到另一种方式，所以我不必拥有那个神奇的数字（99999）（另外，它似乎有点不成熟......）。我并不担心，因为它有效。
