我想从纬度和经度中找到当前位置名称,这是我试过的代码片段,但我的日志在除placemark、placemark.ISOcountryCode和placemark.country我想要placemark.locality和placemark.subLocality的值,但它显示的是空值。-(void)viewWillAppear:(BOOL)animated{[superviewWillAppear:animated];//thiscreatestheCCLocationManagerthatwillfindyourcurrentlocationlocationManager=[[CLL

我正在尝试编写一个简单的方法,该方法提供CLLocationDegrees并返回一个CLPlacemark。看着Apple'sdocumentation,这似乎是一项简单的任务。下面是我扔进Playground的东西:importCoreLocation//thisisnecessaryforasynccodeinaplaygroundimportPlaygroundSupport//thisisnecessaryforasynccodeinaplaygroundPlaygroundPage.current.needsIndefiniteExecution=truefuncgeocod

我有要在我的map应用程序中打开的纬度和经度。我尝试了来自HERE的这段代码.funcgoToMap(){varlat1:NSString=self.venueLatvarlng1:NSString=self.venueLngvarlatitude:CLLocationDegrees=lat1.doubleValuevarlongitude:CLLocationDegrees=lng1.doubleValuevarcoordinate=CLLocationCoordinate2DMake(latitude,longitude)varplacemark:MKPlacemark=MKPla
