Swift开发教程--如何通过定位来获取经纬度

首先，定义和继承协议CLLocationManagerDelegate

var locManager:CLLocationManager?;

self.locManager = CLLocationManager();//[[CLLocationManager alloc] init];

self.locManager!.delegate = self;

self.locManager!.desiredAccuracy = kCLLocationAccuracyBest;

self.locManager!.distanceFilter = 5.0;

//设置定位权限 仅ios8有意义

self.locManager?.requestWhenInUseAuthorization();//前台定位

self.locManager?.startUpdatingLocation();

最后，根据回调来获取经纬度值

func locationManager(manager: CLLocationManager!,didUpdateToLocation newLocation: CLLocation!,fromLocation oldLocation: CLLocation!) {

println("经度：%g",newLocation.coordinate.latitude);

println("纬度：%g",newLocation.coordinate.longitude);

}

func locationManager(manager: CLLocationManager!,didFailWithError error: NSError!) {

println("locationManager error");

}

还有一点，别忘了在info.plist里，加一项：

NSLocationWhenInUseUsageDescription，设为YES
