ios - 使用社交框架在 Facebook 墙上分享位置

Question

我正在尝试将 Facebook 登录上的共享集成到我的应用程序中，但不知何故，我无法实现在 Facebook 墙上共享位置的目的，这里我使用社交框架。

我尝试的代码如下:

SLComposeViewController *fbController=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

    if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
    {
        SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){

            [fbController dismissViewControllerAnimated:YES completion:nil];

            switch(result){
                case SLComposeViewControllerResultCancelled:
                default:
                {
                    NSLog(@"Cancelled.....");
                    // [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];
                    }
                    break;
                case SLComposeViewControllerResultDone:
                {
                    NSLog(@"Posted....");
                }
                    break;
            }};
        [fbController setInitialText:@"This is My Sample Text"];
        [fbController setCompletionHandler:completionHandler];
        [self presentViewController:fbController animated:YES completion:nil];
    }
    else{
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Sign in!" message:@"Please first Sign In!" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
        [alert show];
    }

这样我就可以分享初始文本，但我需要分享的是当前位置。
提前致谢。

对于此导入 MapKit 框架，您可以使用 CLLocationManger 获取当前位置。

NSString  *city;
CLLocationManager *locationManager;

locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
CLLocationCoordinate2D coordinate = [locationManager.location coordinate];
GeoCodeValue=[[NSString alloc] initWithFormat:@"%f,%f",coordinate.latitude,coordinate.longitude];
NSLog(@"userLocation::%@",GeoCodeValue);

CLGeocoder *geocoder = [[CLGeocoder alloc] init];
[geocoder reverseGeocodeLocation:locationManager.location completionHandler:^(NSArray *placemarks, NSError *error) {
    CLPlacemark *placemark = [placemarks objectAtIndex:0];
    city = placemark.thoroughfare;
}];

&将此城市字符串作为文本传递以显示当前位置。

 [fbController setInitialText:@"Current Location is %@",city"];
