Question

我在iOS 7上运行良好的应用程序无法使用iOS 8 SDK。

CLLocationManager 没有返回位置，我也没有在Settings -> Location Services下看到我的应用。我在这个问题上进行了谷歌搜索，但没有出现任何问题。可能有什么不对？

Answer 1

在info.plist

中添加以下内容

键：NSLocationWhenInUseUsageDescription类型：String值：提示消息例如 - 需要您当前的位置

Answer 2

在ios 8+中，您需要在应用时仅向我们请求权限[self.locationManager requestWhenInUseAuthorization]，并且[self.locationManager requestAlwaysAuthorization]始终使用位置

此代码完美适用于ios 8

#pragma mark -
#pragma mark CLLocationManagerDelegate

- (void)startSignificantChangeUpdates
{
    if ([CLLocationManager locationServicesEnabled])
    {
        if (!self.locationManager)
           self.locationManager =  [[CLLocationManager alloc] init];


        self.locationManager.delegate = self;

        // request location when app in use
        [self.locationManager requestWhenInUseAuthorization];
        [self.locationManager startUpdatingLocation];
    }
}



- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {
   [self.locationManager stopUpdatingLocation];

    CLGeocoder * geoCoder = [[CLGeocoder alloc] init];
    [geoCoder reverseGeocodeLocation:newLocation completionHandler:^(NSArray *placemarks, NSError *error) {
    for (CLPlacemark * placemark in placemarks) {
        NSString *country = placemark.ISOcountryCode;
        cityName = [placemark locality];
    }
    }];
}

位置获取错误Ios
