XCode 6.3 MKPointAnnotation setCoordinate缺失

本文介绍了XCode 6.3 MKPointAnnotation setCoordinate缺失的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

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。

I just updated XCode to 6.3 and now I am receiving the below error: MKPointAnnotation does not have a member named 'setCoordinate'.

不确定去哪里，或者我们应该使用其他MK方法。任何帮助都表示赞赏。

Not sure where it went, or if we are supposed to use some other MK method. Any help is appreciated.

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 }

推荐答案

如 MapKit模块中的3.2i API扩散， setCoordinate 方法已被删除：

已移除 MKAnnotation.setCoordinate（CLLocationCoordinate2D）

Removed 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）：

Fortunately, you must now use the simpler assignment syntax (which was already available in previous versions of Swift and the same could be done in Objective-C):

annotation.coordinate = location
