如何从iOS应用程序iOS 7登录到Twitter帐户？

Question

我需要从我的iOS应用程序登录我的推特。我能够检查是否在设备的设置中设置了任何帐户。一旦确认设备中没有配置帐户，我希望能够登录到我的twitter帐户，然后将帐户添加到我的设备中。我很幸运地实现了检查是否在设备中使用ACAccountStore设置了任何帐户。但是，请有人帮助在iOS7中实现后面的部分吗？

Answer 1

SLComposeViewController *sheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];

SLComposeViewControllerCompletionHandler completionBlock = ^(SLComposeViewControllerResult result){
  [sheet dismissViewControllerAnimated:YES completion:Nil];
};
sheet.completionHandler = completionBlock;
sheet.view.hidden = YES;

[_mainViewController presentViewController:sheet animated:YES completion:nil];

Answer 2

  - (IBAction)tweetTapped:(id)sender {
if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{
    SLComposeViewController *tweetSheet = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter];
    [tweetSheet setInitialText:@"Your Tweet Message! :)"];
    if (self.imageString)
    {
        [tweetSheet addImage:[UIImage imageNamed:self.imageString]];
    }

    if (self.urlString)
    {
        [tweetSheet addURL:[NSURL URLWithString:self.urlString]];
    }
    [self presentViewController:tweetSheet animated:YES completion:nil];
}
else
{
    UIAlertView *alertView = [[UIAlertView alloc]
                              initWithTitle:@"Sorry"
                              message:@"You can't tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"
                              delegate:self
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
    [alertView show];
  }
}
