Question

I have a view with two UITextField, one for username, one for password.

I added functionality so the usernameTF return button jumps to the passwordTF. I also made the return button on the passwordTF “Go” which I want to connect to a IBAction I have which will contain the actual login logic.

I tried hooking up the IBAction to the passwordTF’s Did End On Exit method but that just seemed to be getting called when the usernameTF was making the passwordTF the first responder.

I’m using this code to jump from usernameTF to passwordTF:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {
    if (textField == self.usernameTextField) {
        [self.passwordTextField becomeFirstResponder];
    }
    [textField resignFirstResponder];
    return YES;
}

I tried this but it does’t call the method when I press Go/Return:

[self.passwordTextField addTarget:self
                               action:@selector(loginButtonPressed:)
                     forControlEvents:UIControlEventEditingDidEndOnExit];

I also tried connecting the IBAction to the UITextField‘s Editing Did End method which calls the method fine when I press the return button, but it also calls the method when I click any UITextField other than the one I have connected with that method. Any fix?

You can try using this

-(BOOL)textFieldShouldReturn:(UITextField *)textField{
    [textField resignFirstResponder];
    if (textField == txtfEmail)
        [txtfPassword becomeFirstResponder];
    else {
        [self login];
    }
    return YES;
}

Where [self login] is actually the login method being called. Validating login credential from Server or from Database. txtfEmail is Login Name and txtfPassword being the password field. Hope it helps
