         NSString *locatedAt = [[placemark.addressDictionary valueForKey:@"FormattedAddressLines"] componentsJoinedByString:@", "];

         //Print the location to console
         NSLog(@"I am currently at %@",locatedAt);

         address = [[NSString alloc]initWithString:locatedAt];    
         NSLog(@"address:%@",address);
     }];
}

我使用上面的代码通过给出纬度和经度来获取地址，但是控制没有进入地理编码器方法，它跳过它。任何人都可以帮助我。

提前致谢。

这是正常的，因为 reverseGeocodeLocation 中的代码是在块内执行的。块内代码的执行发生在另一个线程中，因此不在主线程中执行，这就是控件不进入地理编码器方法内部的原因。

没关系，控件没有进入方法，但它可以工作，注意输出它会工作。
