iOS开发定位权限

定位权限

如果项目需要开启定位功能，需要在info.plist中设置Privacy - Location Always and When In Use Usage Description和Privacy - Location When In Use Usage Description。

info中配置.png

在需要开启定位权限的地方去弹起授权弹窗
需要设置CLLocationManager属性 （这里是个大坑，必须是属性，如果用局部变量弹不起来弹窗）

@property (nonatomic, strong) CLLocationManager *locationManager;

设置代理及代理方法(可选，非必须设置，开启持续定位才会触发回调，弹窗授权后不触发)

- (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations {
    NSLog(@"更新位置的回调");
}
 
- (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error {
    NSLog(@"错误信息回调");
}

调起定位弹窗

- (void)GetLocationPermissionVerifcationWithController{
    BOOL enable = [CLLocationManager locationServicesEnabled];
    NSInteger state = [CLLocationManager authorizationStatus];
    
    if (!enable || 2 > state) {// 尚未授权位置权限
        if (8 <= [[UIDevice currentDevice].systemVersion floatValue]) {
            NSLog(@"系统位置权限授权弹窗");
            // 系统位置权限授权弹窗
            self.locationManager = [[CLLocationManager alloc] init];
            self.locationManager.delegate = self;
            [self.locationManager requestAlwaysAuthorization];
            [self.locationManager requestWhenInUseAuthorization];
        }
    }
}

已授权判断

BOOL enable = [CLLocationManager locationServicesEnabled];
CLAuthorizationStatus state = [CLLocationManager authorizationStatus];
if (enable && (state == kCLAuthorizationStatusAuthorizedAlways || state == kCLAuthorizationStatusAuthorizedWhenInUse)) {// 已授权位置权限
    }
