ios – XCode 6.3 MKPointAnnotation setCoordinate丢失

我刚刚将XCode更新为6.3,现在我收到以下错误：
MKPointAnnotation没有名为“setCoordinate”的成员.

不知道它在哪里,或者如果我们应该使用一些其他的MK方法.任何帮助是赞赏.

func refreshlocation(lat:String,lon:String,withOffset:Bool = false){


        // 1 Convert the string values to something that can be used.
        let location = CLLocationCoordinate2D(
            latitude: (lat as Nsstring).doubleValue as CLLocationdegrees,longitude: (lon as Nsstring).doubleValue as CLLocationdegrees
        )

        // 2 setup some initial variables.
        let span = MKCoordinateSpanMake(
            (self.locationLatitudeDelta as Nsstring).doubleValue as CLLocationdegrees,(self.locationLongitudeDelta as Nsstring).doubleValue as CLLocationdegrees
        )

        let region = MKCoordinateRegion(center: location,span: span)
        mapView.setRegion(region,animated: true)

        //3 decorate the point and add the point to the map.
        var annotation = MKPointAnnotation()
        annotation.setCoordinate(location) //Error on this line

    }

解决方法

如 iOS 8.3 API Diffs in the MapKit module所述,setCoordinate方法被删除：

Removed MKAnnotation.setCoordinate(CLLocationCoordinate2D)

幸运的是,您现在必须使用更简单的赋值语法(这在之前版本的Swift中已经可以使用,并且可以在Objective-C中完成)：

annotation.coordinate = location
