iOS - MKMapKit,显示注释中用户位置的地址

Question

默认情况下,我们可以在地图视图中显示用户的位置.点击注释引脚时,它将显示"当前位置".但我想将用户的地址显示为街道,城市和国家.我怎么能用CLGeoCoder课来做呢？

Answer 1

做这样的事情:

CLGeocoder *gc = [[[CLGeocoder alloc] init] autorelease];
[gc reverseGeocodeLocation:locationObject completionHandler:^(NSArray *placemark, NSError *error) {
    CLPlacemark *pm = [placemark objectAtIndex:0];
    NSDictionary *address = pm.addressDictionary;
    // do something with the address, see keys in the remark below
}];
