[FIXED] How to populate OTP from user's message box to application directly in iPhone?

Issue

I am working on an internet trading application with its mobile and iPhone applications available. With the recent market trend, we are working on including two-factor authentication. For that, we will be sending a one-time password as a sms on user's registered mobile number.

Is there a way,that the OTP can get automatically populated into application from user's message box in iPhone? What algorithm should I use to make my app read user's message box?

Thanks in advance:)

Solution

You can Access SMS from your app. So better make user to enter his contact number and send SMS to his mobile

-(BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    if (!url) {
        UIApplication * yourapplication =[UIApplication sharedApplication];
        NSString *outputpath =@"appname://data/";
        NSURL *url =[NSURL URLWithString:outputpath];
        [yourapplication openURL:url];
        return NO;
    }

    NSUserDefaults *defaultString =[NSUserDefaults standardUserDefaults];
    NSString * commonString =[url absoluteString];
    if (commonString.length<=15) {
        //
    }
    else
    {
        [defaultString setObject:commonString forKey:@"urlString"];
    }
         //send info to the screen you need and can navigate
    return YES;
}
