| optional

根据anntation生成对应的View。 Generate corresponding View based on annotation.

注意： Note： 1、5.1.0后由于定位蓝点增加了平滑移动功能，如果在开启定位的情况先添加annotation，需要在此回调方法中判断annotation是否为MAUserLocation，从而返回正确的View。 if ([annotation isKindOfClass:[MAUserLocation class]]) { return nil; } After version 5.1.0, the positioning blue dot has added a smooth movement function. If you add an annotation while the positioning is turned on，it is necessary to determine whether the annotation is MAUserLocation in this callback method in order to return the correct View. if ([annotation isKindOfClass:[MAUserLocation class]]) { return nil; }

2、请不要在此回调中对annotation进行select和deselect操作，此时annotationView还未添加到mapview。 Please do not perform select or deselect operations on the annotation in this callback, as the annotationView has not been added to the mapView yet.

Parameters

  mapView | 地图View Map view
  annotation | 指定的标注 Specified annotation

Returns
  生成的标注View Generated annotation View
