ios - 在 Swift 2 中模糊使用 'kGMSMarkerAnimationPop' 错误

Question

我在尝试为 GMSMarker 设置动画时遇到错误，我已按照 Google 文档和各种指南进行操作，但它一直返回错误，下面是我的代码:

func placeMarker(coordinate: CLLocationCoordinate2D) {
    if locationMarker != nil {
        locationMarker.map = nil
    }

    locationMarker = GMSMarker(position: coordinate)
    locationMarker.icon = GMSMarker.markerImageWithColor(purple)
    locationMarker.appearAnimation = kGMSMarkerAnimationPop
    locationMarker.snippet = "The best place on earth."
    locationMarker.map = mapView
}

返回错误 Ambiguous use of 'kGMSMarkerAnimationPop'

如有任何帮助，我们将不胜感激!

Answer 1

至少在 1.12.3 之前，升级 google map pod 是行不通的。

1. 将 GMSMarker.h 中的 GMSMarkerAnimation 更改为:

   typedef enum {
     /** No animation (default). */
     kGMSMarkerAnimationNone = 0,
   
     /** The marker will pop from its groundAnchor when added. */
     kGMSMarkerAnimationPop,
   } GMSMarkerAnimation;
   

   为此:

   typedef NS_ENUM(NSInteger, GMSMarkerAnimation){
     /** No animation (default). */
     kGMSMarkerAnimationNone = 0,
   
     /** The marker will pop from its groundAnchor when added. */
     kGMSMarkerAnimationPop,
   } ;
   

2. 改变

   locationMarker.appearAnimation = kGMSMarkerAnimationPop

   到

   locationMarker.appearAnimation = GMSMarkerAnimation.Pop
