想在iOS上获取城市名称,采用了一个方法
- (void)startedReverseGeoderWithLatitude:(double)latitude longitude:(double)longitude{ CLLocationCoordinate2D coordinate2D; coordinate2D.longitude = longitude; coordinate2D.latitude = latitude; MKReverseGeocoder *geoCoder = [[MKReverseGeocoder alloc] initWithCoordinate:coordinate2D]; geoCoder.delegate = self; [geoCoder start]; } #pragma mark - - (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark { NSString *subthroung=placemark.subThoroughfare; NSString *local=placemark.locality; NSLog(@"城市名:%@-%@-%@",placemark.locality,local,subthroung); if (local) { [cityLabel setText:local]; } } - (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error { }
原文参考:http://blog.csdn.net/diyagoanyhacker/article/details/6412557
上面的文章只给了一个实现类,对于新手来说,比较困难。
我在补充下,
增加框架,coreLocation.framework,MapKit.framework框架。
在实现文件中包括
#import <CoreLocation/CoreLocation.h> #import <Mapkit/Mapkit.h>
同时增加委托
CLLocationManagerDelegate,MKReverseGeocoderDelegate>
直接编译运行,出现
server did not accept client registration 68
经过google,终于找到这是个bug。原文 http://forums.bignerdranch.com/viewtopic.php?f=79&t=2069
解决方法在,实现文件的的#import 和 @implementation 之间增加如下代码(hach crash)
@implementation CLLocationManager (TemporaryHack) - (void)hackLocationFix { CLLocation *location = [[CLLocation alloc] initWithLatitude:42 longitude:-50]; [[self delegate] locationManager:self didUpdateToLocation:location fromLocation:nil]; } - (void)startUpdatingLocation { [self performSelector:@selector(hackLocationFix) withObject:nil afterDelay:0.1]; }
经过重重磨难,终于跑起来了,也获得了经纬度,不过悲剧的是reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark ,方法没有执行。难道是模拟器的是?回家放到设备上看看去~
