IOS 8 如何在 Facebook、Twitter 社区页面上发布消息、图像

Question

IOS 7、8 如何在 Facebook、Twitter 社区页面的墙上发布消息、图片。我尝试使用 SLComposeViewController，它可以在登录用户的墙中发布，但没有看到如何发布到 Facebook 或 Twitter 社区或页面墙。

你可以用 UIActivityViewController 来做到这一点。创建一个按钮插座并在 IBAction 中编写下面的代码。

- (IBAction)Share:(id)sender{


 NSString *shareString=[NSString stringWithFormat:@"Write here what you want to share"];


    NSArray * itemsArray = @[[NSString stringWithFormat:@"%@",shareString]];//if you want to share image here pass url of image in the array.

    NSArray * applicationActivities = nil;
    UIActivityViewController * AVC = [[UIActivityViewController alloc] initWithActivityItems:itemsArray applicationActivities:applicationActivities];


    [self presentViewController:AVC animated:YES completion:nil];
    [AVC setCompletionHandler:^(NSString *act, BOOL done)
     {

         NSString *ServiceMsg = nil;

         if([act isEqualToString:UIActivityTypeMail]) {
             ServiceMsg = @"Mail sent!";
         } else if([act isEqualToString:UIActivityTypePostToTwitter]) {
             ServiceMsg = @"Shared on twitter!";
         } else if([act isEqualToString:UIActivityTypePostToFacebook]) {
             ServiceMsg = @"Shared on facebook!";
         } else if([act isEqualToString:UIActivityTypeMessage]) {
             ServiceMsg = @"SMS sent!";
         } else if([act isEqualToString:UIActivityTypeAddToReadingList]) {
             ServiceMsg = @"Added to Reading List";
         } else if([act isEqualToString:UIActivityTypeCopyToPasteboard]){
             ServiceMsg = @"Link Copied";
         }

         if ( done )
         {
             UIAlertView *Alert = [[UIAlertView alloc] initWithTitle:ServiceMsg message:@"" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil];
             [Alert show];

         }
     }];

}

希望对你有所帮助。
