                  NSLog(@"%@ %@ %@ %@", address,city, state, zip);

                   //NSLog(fullA);
                   fullA=(@"%@ %@ %@ %@", address,city, state, zip);
                 }
               }];
  [messageController setBody:fullA];
  [self presentModalViewController:messageController animated:YES];
  }
  else {

    NSLog(@"%@" , @"Sorry, you need to setup mail first!");
  }

}

我尝试过使用 __block，或者我可以在在线教程中找到的所有内容。

这会打印出 NSLog 中的完整地址。但是，无论我尝试过什么，这都不会出现[messageController setBody:(@"%@ %@ %@ %@",city, state, address, zip)];

并使用 (setBody:@"Hello") 工作得很好......

我确信我可以做一些小事情来解决这个问题，但是我尝试过的一切都失败了。任何想法都会很棒！

用于stringWithFormat设置具有不同对象的主体，如下所示

[messageController setBody:[NSString stringWithFormat:@"%@ %@ %@ %@",city, state, address, zip];

你不能按照你正在做的事情做你正在做的事情。调用reverseGeocodeLocation是异步的。在您取回地址信息之前，您最终会呈现消息控制器。这就是为什么身体总是空的。

您需要修改代码以从完成处理程序中创建和显示消息编写器（但您必须在主队列上调度代码）。

- (IBAction)SendTextTapped:(id)sender{
    if ([MFMessageComposeViewController canSendText]) {
        CLGeocoder *geocoder = [[CLGeocoder alloc] init];

        CLLocation *newerLocation = [[CLLocation alloc]initWithLatitude:21.1700 longitude:72.8300];
        [geocoder reverseGeocodeLocation:newerLocation completionHandler:^(NSArray *placemarks, NSError *error) {
            if (error) {
                NSLog(@"Geocode failed with error: %@", error);
                return;
            }

            NSString *body = @"";
            if (placemarks && placemarks.count > 0) {
                CLPlacemark *placemark = placemarks[0];

                NSDictionary *addressDictionary =
                placemark.addressDictionary;

                NSLog(@"%@ ", addressDictionary);
                NSString *address = [addressDictionary
                                   objectForKey:(NSString *)kABPersonAddressStreetKey];
                NSString *city = [addressDictionary
                                   objectForKey:(NSString *)kABPersonAddressCityKey];
                NSString *state = [addressDictionary
                                   objectForKey:(NSString *)kABPersonAddressStateKey];

                                   objectForKey:(NSString *)kABPersonAddressZIPKey];

                body = [NSString stringWithFormat:@"%@ %@ %@ %@", address,city, state, zip];
            }

        }];
    } else {

    }
}
