我正在使用UIActivityViewController,它提供了一些默认文本和链接.使用所有社交媒体(短信,电子邮件,推特),将显示默认文本和URL.但是,在显示URL图像时使用FB,默认文本不显示(它只是空白).以下是代码:

    NSString *shareStr = [NSString stringWithFormat:@""some text"];
    NSURL *website = [NSURL URLWithString:@"website"];
    NSArray *shareAray = @[shareStr,website];

    [self viewWillDisappear:YES];

    UIActivityViewController *activityController = [[UIActivityViewController alloc]initWithActivityItems:shareAray
                                                                                    applicationActivities:nil];

    if([activityController respondsToSelector:@selector(popoverPresentationController)] )
        activityController.popoverPresentationController.barButtonItem = self.shareButton;


    [self presentViewController:activityController
                       animated:YES completion:nil];

    [activityController setCompletionHandler:^(NSString *activityType, BOOL completed){
        if (!activityType || UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
        {
            [self viewWillAppear:YES];
        }
    }];

更新:如下面其他人所述,FB不再允许预填.以下是视频的另一个链接,其中提供了允许内容和不允许内容的示例:https: //developers.facebook.com/docs/apps/review/prefill

我想使用UIActivityViewController分享简单的文本我使用swift,使用xcode 6.3代码非常简单,非常适合照片,但不仅仅是文本,我不想包含任何带有objectsToShare的web URL,只是干净的文本这是代码:

var objectsToShare: ["some text to share"]! 
let activityVC = UIActivityViewController(activityItems: objectsToShare, applicationActivities: nil)

//handler for completed task
activityVC.completionHandler = {(activityType, completed:Bool) in
            if !completed {
                println("cancelled")
                return
            }
reportCompleted() //report to server it's done.
 }

//Excluded Activities Code
activityVC.excludedActivityTypes = [UIActivityTypeAirDrop, UIActivityTypeAddToReadingList, UIActivityTypeCopyToPasteboard ]

//activate the share view
self.presentViewController(activityVC, animated: true,  completion: {
            (complete)  in
            println(complete)

        })

现在我知道这一切都取决于用户有Facebook - 不仅在他的手机上,而且在他的设置上.(我直接从我的手机6尝试了这个,它有Facebook设置,而不是来自模拟器)这个代码曾经工作正常,仍然适用于图像,而不是文本,但由于某种原因,它停止工作文本共享,也许文本本身有关,也许我的代码不好,或者Facebook,改变一些东西.

感谢您对此主题的任何想法.

为了让事情更奇怪,我发现了两件更奇怪的事情.

1. 发布文本的代码正在模拟器上工作(只要你在设置facebook中添加)
2. 如果我添加到网址,它也可以工作(在设备中)如果我删除网址它不起作用.

//有效的代码:

var myWebsite = NSURL(string: "http://www.someurl.com/")
