Easy to use UIAlertView subclass to get text input

README

Usage:


-(void)doStuff:(id)sender {
    NSString *text = [RSAlertViewTextInput textWithTitle:@"Enter your zipcode" cancelBtn:@"Cancel" submitBtn:@"Submit"];
    NSLog(@"nom: %@", text);
}

Easy to use, one line of code. Or you can initialize it and figure it out that way.
