保留Twitter中的用戶名iOS5 iPhone

Question

我想點擊添加一個按鈕，允許用戶在iOS 5中登錄他們的Twitter帳戶，但我希望他們的twitter處理能夠填充到UITextField中。我有代碼確保他們的iPhone運行iOS 5並且他們的帳戶已啓用。我如何保留他們的手柄？

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"]];

您可以將其句柄從ACAccount對象中取出並保存在默認或其他位置。
