Display the iPhone keyboard

Question

I've run into a problem with the UITextView that seems to be related to having a scrollable view within a scrollable view.

In order to remedy this i thought i would attempt to write my own multiline (but not scrollable) text view. Given the core graphics methods, and the UITextInputTraits class it seems like this should be feasable. The only thing i cant figure out is wether or not its possible to display (and catch events) for the system wide keyboard.

Is this even possible using the SDK?

What I did in a similar situation, is made a hidden UITextField, and set its delegate to your class where you can implement the appropriate UITextFieldDelegate methods to intercept the key's pressed.

something like this:

UITextField *myHiddenTextField = [[UITextField alloc] initWithFrame: cgRectZero()];
myHiddenTextField.delegate = self;
[myHiddenTextField becomeFirstResponder];

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
//use string here for the text input
return false;
}
