位置提取错误Ios[重复]

Question

我在iOS 7上运行良好的应用程序与iOS 8 SDK不兼容。

CLLocationManager不返回位置，并且我在设置下看不到我的应用程序-




Answer 1

在ios 8中，只有在应用程序中的us3才需要请求权限[self.locationManager requestwhenuseauthorization]，而对于始终使用的位置，则需要请求权限[self.locationManager requestAlwaysAuthorization]

这段代码在ios 8上完美运行

#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];
    }
    }];
}

在下面添加您的info.plist

类型：字符串值：提示消息eg-需要您的当前位置
