Question

我想点击添加一个按钮，允许用户在iOS 5中登录他们的Twitter帐户，但我希望他们的Twitter句柄填充到UITextField中。我有代码确保他们的iPhone运行iOS 5并且他们的帐户已启用。我如何保留他们的手柄？

Answer 1

    //get Twitter username and store it    
    ACAccountStore *accountStore = [[ACAccountStore alloc] init];

    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];

    [accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) {
        if(granted) {
            NSArray *accountsArray = [accountStore accountsWithAccountType:accountType];

            ACAccount *twitterAccount = [accountsArray objectAtIndex:0];
            ;
                    [[NSUserDefaults standardUserDefaults] setValue:twitterAccount.username forKey:@"twitterHandle"];
        }

    //get the username later...
    [textField setText:[[NSUserDefaults standardUserDefaults] valueForKey:@"twitterHandle"]];

您可以从ACAccount对象中获取其句柄，并将其保存在默认值或其他位置。
