Ios 如何在MapView注释中将右侧访问器的边框调整到右上角？

我想在右上角添加右访问器图像（交叉图像），如下图所示，但无法获取其代码： 我使用下面的代码，但它没有给我我需要的。我需要在下面的图片所示的地方交叉按钮

annView.leftCalloutAccessoryView = [UIButton buttonWithType:UIButtonTypeContactAdd];

       UIImage *listImage = [UIImage imageNamed:@"Close_normal.png"];
       UIButton *listButton = [UIButton buttonWithType:UIButtonTypeCustom];

       // get the image size and apply it to the button frame
      // listButton.frame = CGRectMake(0,0,56,68);

       CGRect listButtonFrame = listButton.frame;


    listButtonFrame.size = listImage.size;
       listButton.frame = listButtonFrame;

       [listButton setImage:listImage forState:UIControlStateNormal];

   annView.rightCalloutAccessoryView = listButton;

然后我还要做的是，当我点击十字按钮时，它会关闭信息弹出窗口并删除注释

- (void) mapView:(MKMapView *)mv annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
 {
if( // left accessor is clicked then execute this code)  // what should i write here
 {
 SiteAnnotation *site = (SiteAnnotation *)view.annotation;
  if(site.category == -1) {
   if(addressAnnotation) {
       [mapView removeAnnotation:addressAnnotation];
AddViewController *vc = [[[AddViewController alloc]        initWithCoordinate:addressAnnotation.coordinate] autorelease];


   [self.delegate pushViewController:vc animated:YES];

   }
 }
        else {
             [self showSiteDetails:site.identifier];
             }
}
 else if (// if right accessor cross image is clicked)
{
  // Then here the code to dismiss the pop up and annotation pin on map

}
}

您可以检查以下代码：

在上面的方法和控制标记中使用标记，使该标记在下面工作

 annView.leftCalloutAccessoryView.tag=1;
        annView.rightCalloutAccessoryView.tag=2;



- (void) mapView:(MKMapView *)mv annotationView:(MKAnnotationView *)view calloutAccessoryControlTapped:(UIControl *)control
{
    SiteAnnotation *site = (SiteAnnotation *)view.annotation;


    // Left Accessory Button Tapped

    if(site.category == -1) {


        if ([control tag] == 1) {


            if(addressAnnotation) {

so on...
}

下一次尝试

else if ([control tag] == 2) {

            // "Right Accessory Button Tapped


            UIAlertView *alert1 = [[UIAlertView alloc] initWithTitle:@"" message:@"Touch and hold the pin icon to drag it around." delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Done", nil];
            [alert1 show];
            [alert1 release];
        }

然后在方法上

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex

{

 UIAlertView *alert_pin = [[UIAlertView alloc] initWithTitle:@"" message:@"cancel button click it " delegate:nil cancelButtonTitle:nil otherButtonTitles:@"Done", nil];

                [alert_pin show];
                [alert_pin release];

                [mapView removeAnnotation:addressAnnotation];
                [addressAnnotation release];
                addressAnnotation = nil;

            }

使用警报并要求用户解除警报，或者不使用仅调用上的直接解除按钮
