若是是xcode6和ios 8的話,須要調用 CLLocationManager requestAlwaysAuthorization 方法,具體步驟以下:ios
1. @interface裏:
CLLocationManager *locationManager;
2. 初始化:
locationManager = [[CLLocationManager alloc] init];
3. 調用請求:
[locationManager requestAlwaysAuthorization];
[locationManager startUpdatingLocation];
4. 在 info.plist里加入:
NSLocationWhenInUseDescription,容許在前臺獲取GPS的描述
NSLocationAlwaysUsageDescription,容許在後臺獲取GPS的描述xcode
ps:調用請求前加上ios版本判斷就完美了。code
完美一下:ip
// 判斷是否 iOS 8
if([self.locationManager respondsToSelector:@selector(requestAlwaysAuthorization)]) {
[self.locationManager requestAlwaysAuthorization]; // 永久受權
[self.locationManager requestWhenInUseAuthorization]; //使用中受權
}
[self.locationManager startUpdatingLocation];it
