Question

我想在右上角添加正确的访问者图像（交叉图像），如下图所示，但我无法获取代码：我使用下面的代码，但它没有给我我需要的东西。我需要在下图所示的地方使用十字按钮。

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;

enter image description here

然后我还要做的是当我点击十字按钮时它应该关闭弹出的信息并删除注释

- (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

}
}

您可以查看以下代码：

使用上述方法中的标记和控制标记来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...
}

接下来尝试

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

- (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或不使用直接解除按钮。

如何在MapView注释中将右访问者的框架调整到右上角？
