如何在Map视图中更改rightCalloutAccessoryView的注释视图按钮的图像？我使用了以下方法在注释视图中设置按钮。

annotationView!.rightCalloutAccessoryView = UIButton(type: .detailDisclosure)

(annotationView?.rightCalloutAccessoryView as! UIButton).setImage(UIImage(named: "abc"), for: .normal)

我也试过自定义按钮，它不会改变

Answer 1

Swift 4

创建按钮，设置图像并在rightCalloutView中指定。

public function imports($aid)
{
  $file_data = $this->csvimport->get_array($_FILES["csv_file"]["tmp_name"]);
  foreach(array_slice($file_data, 1) as $row)
  {
    $pid = $this->m_csvimport->getid($row["nip"]);
    $array [] =array(
      'aid' => $aid,
      'pid' => $pid,
      'kodeunik' => '',
      );
  }
  /* print_r($array) to check the data */

  $this->m_csvimport->inserts($array);
}

尝试以这种方式创建Button，设置image并将Button设置为rightCalloutAccessoryView。

let button = UIButton(frame: CGRect(x: 0, y: 0, width: 20, height: 20))
button.setImage(UIImage(named: "abc"), for: .normal)
annotationView!.rightCalloutAccessoryView = button

SWIFT 3.0 试试这个您可以在标注中设置服务器URL图像。

func mapView(_ mapView: GMSMapView, markerInfoWindow marker: GMSMarker) -> UIView? {
        marker.tracksInfoWindowChanges = true
        let CustomWindowDisplay:CustomWindow = Bundle.main.loadNibNamed("View", owner: self, options: nil)![0] as! CustomWindow
        let arrImages:NSArray = (dictDataOfPropertyData.value(forKey: "property_images") as? NSArray)!
        if arrImages.count != 0{
            let strImage:String = (arrImages1.object(at: 0) as! NSDictionary).value(forKey: "property_photo") as! String

            let urlofImg:NSURL = NSURL.init(string: strImage)!
            CustomWindowDisplay.imgPropertyPhoto.sd_setImage(with: urlofImg as URL, placeholderImage: UIImage(named: "placeholder_main_list.png"), options: .highPriority)
        }
    }
