RootViewController *objYourViewController = [[RootViewController alloc] initWithNibName:@"RootViewController" bundle:nil];
CATransition* transition = [CATransition animation];
transition.duration = 1.0;
transition.type = kCATransitionPush;
transition.subtype = kCATransitionPush;
[self.navigationController.view.layer addAnimation:transition forKey:kCATransition];
[self.navigationController pushViewController:objYourViewController animated:YES];

这用于指向当前位置。现在我想在文本字段或表格视图中获取当前位置的详细信息，所以如果有人知道，请帮助我。

我用过下面的代码..

首先添加文件MKReverseGeocoderDelegate...h

MKReverseGeocoder在文件中创建对象后，.h如下所示..

MKReverseGeocoder *mkReverseGeocoder;

然后在您的UIButtonAction 事件中像下面一样使用它

-(IBAction)btnFindMe_Clicked:(id)sender{
    if(mkReverseGeocoder)
    {
        [mkReverseGeocoder autorelease];
    }
    
    mkReverseGeocoder = [[MKReverseGeocoder alloc] initWithCoordinate:[currLocation coordinate]];
    
    [mkReverseGeocoder setDelegate:self];
    [mkReverseGeocoder start];
}

下面的方法是委托方法MKReverseGeocoder

//mkreversegeocoder protocol methods

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFailWithError:(NSError *)error
{

    [appDelegate hideLoadingView];
    UIAlertView *alt=[[UIAlertView alloc]initWithTitle:@"Error" message:@"Try Again After Sometime" delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil, nil];
    [alt show];
    [alt release];
//    NSLog(@"\n\n Error is %@",[error description]);
}

- (void)reverseGeocoder:(MKReverseGeocoder *)geocoder didFindPlacemark:(MKPlacemark *)placemark
{

    [appDelegate hideLoadingView];
    NSLog(@"\n\n Address Dict : %@",[[placemark addressDictionary] description]);
    txtCity.text=[[placemark addressDictionary] objectForKey:@"City"];
    txtState.text=[[placemark addressDictionary] objectForKey:@"State"];
    txtAddress1.text=[[placemark addressDictionary] objectForKey:@"Street"];
    txtAddress2.text=[[placemark addressDictionary] objectForKey:@"SubLocality"];
    //[NSString stringWithFormat:@"%@", [[gpsTextView addressDictionary] description], ];
}

另请参阅此链接的示例，但它的另一个代码.. 以上是我的自定义代码... how-to-get-current-latitude-and-longitude-in-iphone/
