iOS應用利用自帶的地圖進行定位

現在的app應用，幾乎每個應用都帶有定位功能，利用蘋果自帶的api就可以很快的實現定位功能，當然還要在info.plist文件中配置定位權限（自行腦補吧，ios10好像每個權限，不管你用了沒，都要配置，不用上架都不讓你上）。下面的代碼是我從工具類中抽取出來的，作爲參考。

#pragma mark 定位------------------------------------------------
#pragma mark - 初始化定位管理器並開始定位
- (void)startLocationWithBlock:(successBlock)success
{
    _locationSuccess = success;
    //定位管理器
    _locationManager = [[CLLocationManager alloc] init];
    _geocoder = [[CLGeocoder alloc] init];
    
    if (![CLLocationManager locationServicesEnabled])
    {
        [_myAlertView myAlertView:@"定位服務沒有打開！請到“設置->隱私->定位服務”中打開定位服務。" andButtonText:@"確定"];
        return;
    }
    
    //如果沒有授權則請求用戶授權
    if ([CLLocationManager authorizationStatus] == kCLAuthorizationStatusNotDetermined)
    {
        [_locationManager requestWhenInUseAuthorization];
    }
    else if([CLLocationManager authorizationStatus] ==kCLAuthorizationStatusAuthorizedWhenInUse)
    {
        //設置代理
        _locationManager.delegate = self;
        //設置定位精度
        _locationManager.desiredAccuracy = kCLLocationAccuracyBest;
        //啓動跟蹤定位
        [_locationManager startUpdatingLocation];
    }
}

#pragma mark 跟蹤定位代理方法，每次位置發生變化即會執行（只要定位到相應位置）
//可以通過模擬器設置一個虛擬位置，否則在模擬器中無法調用此方法
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations
{
    CLLocation *location = [locations firstObject];   //取出第一個位置
    CLLocationCoordinate2D coordinate = location.coordinate;  //位置座標
    //NSLog(@"經度：%f,緯度：%f,海拔：%f,航向：%f,行走速度：%f",coordinate.longitude,coordinate.latitude,location.altitude,location.course,location.speed);
    
    // 根據座標位置進行反地理編碼
    [self getAddressByLatitude:coordinate.latitude longitude:coordinate.longitude];
    
    //如果不需要實時定位，使用完即使關閉定位服務
    [_locationManager stopUpdatingLocation];
}

#pragma mark 根據座標取得地名
-(void)getAddressByLatitude:(CLLocationDegrees)latitude longitude:(CLLocationDegrees)longitude
{
    //反地理編碼
    CLLocation *location = [[CLLocation alloc] initWithLatitude:latitude longitude:longitude];

    [_geocoder reverseGeocodeLocation:location completionHandler:^(NSArray *placemarks, NSError *error){
        
        CLPlacemark *placemark = [placemarks firstObject];
        
        NSLog(@"City:%@", placemark.addressDictionary[@"City"]);
        NSLog(@"Country:%@", placemark.addressDictionary[@"Country"]);
        NSLog(@"CountryCode:%@", placemark.addressDictionary[@"CountryCode"]);
        NSLog(@"FormattedAddressLines:%@", placemark.addressDictionary[@"FormattedAddressLines"][0]);
        NSLog(@"Name:%@", placemark.addressDictionary[@"Name"]);
        NSLog(@"State:%@", placemark.addressDictionary[@"State"]);
        NSLog(@"Street:%@", placemark.addressDictionary[@"Street"]);
        NSLog(@"SubLocality:%@", placemark.addressDictionary[@"SubLocality"]);
        NSLog(@"Thoroughfare:%@", placemark.addressDictionary[@"Thoroughfare"]);
        
        NSDictionary *dict = @{@"addressStr":[NSString stringWithFormat:@"%@%@%@", placemark.addressDictionary[@"City"], placemark.addressDictionary[@"SubLocality"], placemark.addressDictionary[@"Street"]], @"lat":[NSNumber numberWithDouble:latitude], @"lng":[NSNumber numberWithDouble:longitude]};
        _locationSuccess(dict);
        _locationSuccess = nil;
    }];
}

可以根據自己的需求再做封裝吧，畢竟每個人的習慣都不一樣！
