    溫馨提示:易賢網(wǎng)小編為您整理了“iOS8 根據(jù)經(jīng)緯度顯示地名”,方便廣大網(wǎng)友查閱!

    我們很多時候做項目的時候都選用通過手機獲取定位,然后傳數(shù)據(jù)給后臺,這是iOS8根據(jù)經(jīng)緯度顯示地名的demo

    //1.導入框架

    */

    -(void)getLocationAll

    {

    self.locationManager = [[CLLocationManageralloc]init];

    _locationManager.delegate =self;

    _locationManager.desiredAccuracy =kCLLocationAccuracyBest;

    _locationManager.distanceFilter =10;

    [_locationManagerrequestAlwaysAuthorization];//添加這句

    [_locationManagerstartUpdatingLocation];

    }

    /*

    //通過經(jīng)緯度得到當前地理位置

    -(void)change{

    defaluts=[NSUserDefaultsstandardUserDefaults];

    CLLocationCoordinate2D coordinate;

    coordinate.latitude = [[NSStringstringWithFormat:@"];

    coordinate.longitude = [[NSStringstringWithFormat:@"];

    CLLocation *newLocation=[[CLLocationalloc]initWithLatitude:coordinate.latitudelongitude: coordinate.longitude];

    CLGeocoder *geocoder=[[CLGeocoderalloc] init];

    [geocoder reverseGeocodeLocation:newLocationcompletionHandler:^(NSArray* placemarks,NSError* error)

    {

    MKPlacemark*placemark = [placemarks objectAtIndex:0];

    LocationAddress = [NSStringstringWithFormat:@"@", placemark.locality, placemark.subLocality,placemark.thoroughfare, placemark.subThoroughfare];

    [defaluts setObject:LocationAddress forKey:@"address"];

    NSLog(@"終極目標:1:%@2:%@3:%@4:%@", placemark.locality, placemark.subLocality,placemark.thoroughfare,placemark.subThoroughfare);

    }];

    #pragma mark--實現(xiàn)CLLocationManagerDelegate的代理方法,獲取地理位置(鑌)===========================================================================

    //(1)獲取到位置數(shù)據(jù),返回的是一個CLLocation的數(shù)組,一般使用其中的一個

    - (void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations

    {

    CLLocation *currLocation = [locations lastObject];

    NSLog(@"經(jīng)度=%f緯度=%f高度=%f", currLocation.coordinate.latitude, currLocation.coordinate.longitude, currLocation.altitude);

    jingduStr =[NSStringstringWithFormat:@"%f", currLocation.coordinate.latitude];

    weiduStr =[NSStringstringWithFormat:@"%f", currLocation.coordinate.longitude];

    NSLog(@"jijijijijij:%@",jingduStr);

    [self change];

    }

    //(2)獲取用戶位置數(shù)據(jù)失敗的回調(diào)方法,在此通知用戶

    - (void)locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error

    {

    if ([error code] ==kCLErrorDenied)

    {

    //訪問被拒絕

    }

    if ([errorcode] == kCLErrorLocationUnknown) {

    //無法獲取位置信息

    }
