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
