在ios 6.0中,您可以实现如下(您必须将社交框架添加到您的项目中)

 #import <Social/Social.h>

 - (void)ShareFacebook
 {
    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]autorelease];
    [alert show];
 }
}
