Question

我一直在使用此代码进行推特发布。

SLComposeViewController *fbController=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];


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

        [fbController dismissViewControllerAnimated:YES completion:nil];

        switch(result){
            case SLComposeViewControllerResultCancelled:
            default:
            {
                NSLog(@"Cancelled.....");

            }
                break;
            case SLComposeViewControllerResultDone:
            {
                NSLog(@"Posted....");
                UIAlertView *alertView = [[UIAlertView alloc]
                                          initWithTitle:@"Success"
                                          message:@"Posted Successfully"
                                          delegate:self
                                          cancelButtonTitle:@"OK"
                                          otherButtonTitles:nil];
                [alertView show];

            }
                break;
        }};

    [fbController addImage:[UIImage imageNamed:@"1.jpg"]];
    [fbController setInitialText:@"Check out this article."];
    //[fbController addURL:[NSURL URLWithString:@"http://soulwithmobiletechnology.blogspot.com/"]];
    [fbController setCompletionHandler:completionHandler];
    [self presentViewController:fbController animated:YES completion:nil];
}

如果用户未设置推特帐户，则显示具有设置和取消按钮的提醒。但它没有在设备中显示警报？有人可以帮我吗。提前谢谢。

Answer 1

Facebook分享也是如此。删除测试：

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])

如果用户的Twitter帐户尚未在iOS 6中设置，则上述测试将评估为false，并且不会执行任何共享代码。

相反，如果您跳过检查并尝试呈现 SLComposeViewController ，iOS将提示用户设置他们的Twitter帐户。

Answer 2

BOOL canCompose=  [SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter];

    if (canCompose) {


        SLComposeViewController *fbCompose=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
        [fbCompose setInitialText:addressLabel.text];
        [self presentViewController:fbCompose animated:YES completion:nil];
    }

尝试此代码而不是使用completionHandler
