XCode 6.3 MKPointAnnotation setCoordinate缺失

标签: ios xcode swift mkpointannotation

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。

不知道它去了哪里,或者我们是否应该使用其他MK方法。任何帮助表示赞赏。

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

    }

正如iOS 8.3 API Diffs in the MapKit module中所述,setCoordinate方法已被移除:

  

已移除 MKAnnotation.setCoordinate(CLLocationCoordinate2D)


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

annotation.coordinate = location
