Question

Im working on a large ios project with multiple xibs and several textfields in almost every one of them.
I need to create a validation class which identifies whether a text field holds nil value or not and then sends the result in BOOL.

The validation class needs to be working on an immediate child level of UIKit.h framework.

How to do it?

Answer 1

Do something like this.

for(UIView* subView in [self.view subViews])
{
    if([subView isKindOfClass:[UITextView class]])
    {
        UITextView* textView = (UITextView*) subView;
        if([textView.text isEqualToString:@""])
        {
            UIAlertView* alert //alloc, initialize with text something like this "Please fill up all text."
            [alert show];
            [alert release];

            break;
        }
    }
}      

Although giving more description to your question would help you to get even more better answer!
