我想在 Facebook 上分享应用程序中的照片和一些文字。我用SLComposeViewController课堂来分享。

我的问题是，当我点击 Facebook 按钮时，会出现一个对话框，其中包含我要发布的图像，但在模拟器中，默认文本没有出现在设备中，它工作得非常好。此代码在模拟器和设备中都适用于 Twitter。为了更清楚，我添加了代码和图像

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
    SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];
    
    SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result)
    {
        if (result == SLComposeViewControllerResultCancelled)
        {
            NSLog(@"Cancelled");
            
        } else
        {
            UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Congratulations!" message:@"Photo is posted to facebook Wall." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
            [alert show];
        }
        [controller dismissViewControllerAnimated:YES completion:Nil];

    };
    
    controller.completionHandler =myBlock;
    str=[NSString stringWithFormat:@"Text to share"];
    
    [controller setInitialText:str];
    [controller addImage:savedImage];
    [self presentViewController:controller animated:YES completion:Nil];
}

在此处输入图像描述

- (IBAction)facebookPost:(id)sender {

    if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

        SLComposeViewController *mySLComposerSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

        [mySLComposerSheet setInitialText:@"Social Framework test!"];

        [mySLComposerSheet addImage:[UIImage imageNamed:@"myImage.png"]];

        [mySLComposerSheet addURL:[NSURL URLWithString:@"http://stackoverflow.com"]];

        [mySLComposerSheet setCompletionHandler:^(SLComposeViewControllerResult result) {

             switch (result) {
                 case SLComposeViewControllerResultCancelled:
                     NSLog(@"Post Canceled");
                     break;
                 case SLComposeViewControllerResultDone:
                     NSLog(@"Post Sucessful");
                     break;

                 default:
                     break;
             }
         }];

        [self presentViewController:mySLComposerSheet animated:YES completion:nil];
    }
}

试试这个............这是我为我的项目所做的

str=@"Text to share";

[controller setInitialText:str];

[controller setInitialText:@"Text to share"];
