MKReverseGeocoder“在iOS 5中已弃用" [英] MKReverseGeocoder "deprecated in iOS 5"

问题描述

它说它在iOS 5中已弃用".

It say it is "deprecated in iOS 5".

- (void)viewDidLoad {
    [super viewDidLoad];
    CLGeocoder *geocoder = [[CLGeocoder alloc] init];

    [geocoder reverseGeocodeLocation:self.locationManager.location // You can pass aLocation here instead
                   completionHandler:^(NSArray *placemarks, NSError *error) {

                 dispatch_async(dispatch_get_main_queue() , ^ {
                           // do stuff with placemarks on the main thread

                           CLPlacemark *place = [placemarks objectAtIndex:0];

                           NSString *zipString = [place.addressDictionary valueForKey:@"ZIP"];

                           [self performSelectorInBackground:@selector(showWeatherFor:) withObject:zipString];



                       }
            }
 }

推荐答案

MKReverseGeocoder在iOS4之后的所有固件中均已弃用.这只是意味着现在使用过时的类已经过时了，皱着眉头.改为使用CLGeocoder，

MKReverseGeocoder is deprecated in all firmwares after iOS4. This just means that it is now obsolete and frowned upon to be using the outdated class. Use CLGeocoder instead, like so:

    CLGeocoder *geocoder = [[CLGeocoder alloc] init];

        [geocoder reverseGeocodeLocation:self.locationManager.location // You can pass aLocation here instead 
                       completionHandler:^(NSArray *placemarks, NSError *error) {

                           dispatch_async(dispatch_get_main_queue(),^ {
                               // do stuff with placemarks on the main thread

                           if (placemarks.count == 1) {

                           CLPlacemark *place = [placemarks objectAtIndex:0];


                           NSString *zipString = [place.addressDictionary valueForKey:@"ZIP"];

                           [self performSelectorInBackground:@selector(showWeatherFor:) withObject:zipString];

                           }

     });

}];

如果您要对地理编码的硬编码坐标对本身进行反向编码-

If you want to reverse geocode a hardcoded pair of coordinates perse --

使用您的纬度和经度初始化CLLocation位置:

Initialize a CLLocation location with your latitude and longitude:

    CLLocation *aLocation = [[CLLocation alloc] initWithLatitude:latitude longitude:longitude];

我还想指出，您仍然可以使用MKReverseGeocoder.不过，可能会在将来的iOS更新中将其删除.

I also want to point out that you can still use MKReverseGeocoder. It may be removed with future iOS updates though.
