[ios][swift]swift GPS传感器的调用
在Info.plist文件中添加如下配置:
(1)NSLocationAlwaysUsageDescription
(2)NSLocationWhenInUseUsageDescription
swift其实做法类似objectc:
locationManager=[[CLLocationManager alloc] init];
locationManager.delegate=self;
locationManager.desiredAccuracy=kCLLocationAccuracyBest;
locationManager.distanceFilter=
10
;
if
(iOSVersion>=
8
) {
[locationManager requestWhenInUseAuthorization];
//使用程序其间允许访问位置数据(iOS8定位需要)
}
[locationManager startUpdatingLocation];
//开启定位
class xxxxx: UIViewController,CLLocationManagerDelegate{
m_lm = CLLocationManager()
m_lm.delegate = self
m_lm.desiredAccuracy = kCLLocationAccuracyBest
m_lm.distanceFilter = kCLLocationAccuracyKilometer
if #available(iOS 8.0, *) {
m_lm.requestAlwaysAuthorization()
m_lm.requestWhenInUseAuthorization()
}
m_lm.startUpdatingLocation()
print(locations)
}
import UIKit import CoreLocation class ViewController: UIViewController , CLLocationManagerDelegate { var locationManager : CLLocationManager!
