Question

I would like to call my login method AFTER the keyboard was dismissed – since I want to start animation and change the UIView alpha to 0.5 until the response.

- (BOOL)textFieldShouldReturn:(UITextField *)theTextField {
    if (theTextField == self.passwordText){
        //hide the keyboard
        [theTextField resignFirstResponder];

        [self validateCredentialsRemotely];

    }else{
         [self.passwordText becomeFirstResponder];
    }
    return YES;
}

The keyboard is not being dismissed before the call to the method validateCredentialsRemotely and the screen freezes while the keyboard is displayed. I would like it to be dismissed first, and then call the method.

Use this notifications..

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillShow:) name:UIKeyboardWillShowNotification object:nil];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];

In keyboardWillHide method call your validateCredentialsRemotely method,This may solve your first issue
