XCode 6.3 MKPointAnnotation setCoordinate 缺失

XCode 6.3 MKPointAnnotation setCoordinate missing

我刚刚将 XCode 更新到 6.3,现在我收到以下错误: MKPointAnnotation 没有名为 'setCoordinate'.

不确定它去了哪里,或者我们是否应该使用其他 MK 方法。感谢任何帮助。

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

    }

iOS 8.3 API Diffs in the MapKit module 中所述,setCoordinate 方法已删除:

Removed MKAnnotation.setCoordinate(CLLocationCoordinate2D)


幸运的是,您现在必须使用更简单的赋值语法(在 Swift 的早期版本中已经可用,在 Objective-C 中也可以这样做):

annotation.coordinate = location
