ios – SLCOmposeviewcontroller twitter共享警报问题

概述我一直在使用此代码进行推特发布. SLComposeViewController *fbController=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];if([SLComposeViewController isAvailableForServiceType:SLSer 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];}

如果用户没有设置推特帐户,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.提前致谢 .

解决方法 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.
