Войти с Tumblr в UIWebView

Question

Я использую аутентификацию входа в систему tumbler через oauth. Я следую этому URL: http://codegerms.com/login-with-tumblr-in-uiwebview-using-xcode-6-part-3/ для аутентификации входа и получения токена доступа и секретного ключа для API Tumblr в iOS через вход в UIWebview.

Я использую этот блок кода.

    [super viewDidLoad]; 

    // clientID = @"Tjta51N6kF6Oxmm1f3ytpUvMPRAE1bRgCgG90SOa0bJMlSlLeT"; 
    // secret = @"lrlQPNx3Yb1nRxp4qreYXvUURkGUmYCBoQacOmLTDRJAc7awRN";

    NSString* httpBody = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 

    accessToken = [[OAToken alloc] initWithHTTPResponseBody:httpBody]; 

    NSString *OAuthKey = accessToken.key; // HERE YOU WILL GET ACCESS TOKEN 

    NSString *OAuthSecret = accessToken.secret; //HERE YOU WILL GET SECRET TOKEN 

    UIAlertView *alertView = [[UIAlertView alloc] 
           initWithTitle:@"Tumblr Token" 
           message:OAuthSecret 
           delegate:nil 
           cancelButtonTitle:@"OK" 
           otherButtonTitles:nil]; 
    [alertView show]; 




} 

Каждая вещь работает нормально, но при входе в то

if ([[[request URL] scheme] isEqualToString:@"tumblr"]) { 
} 

следует назвать в shouldStartLoadWithRequest метод делегата , но данное условие не выполнено. так что я не могу проверить oauth_verifier и не смог получить accessToken. Пожалуйста, помогите.

Answer 1

Вы должны быть использовать HTTPS вместо HTTP для каждого URL из Tumblr.It будет работать отлично. Спасибо.
