Swift开发教程--如何通过定位来获取经纬度

Posted 2022-12-10 wanglixin1999

首先，定义和继承协议CLLocationManagerDelegate

var locManager:CLLocationManager?;

然后调用：

        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
