UIKeyboard detection

[ZunePod]

I need to find a way to detect key presses when the Keyboard pops up, and possibly telling me which letter was pressed?

Will I have to make my own keyboard here or what?

It depends which control you're using. Some things like the UITextField have a delegate method for handling key presses.

I'm using UITextView.

In that case, you can use:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text

Where "text" is the text or key that was just entered.

Ah cool, I came across that but it didn't seem to be what I was looking for.

Also, how would I see if the delete key was pressed?

The string entered is nothing. You can only capture the backspace when there is text in the view, otherwise the delegate method isn't called.

I tried it (just got around to it) and the method isn't being called. I've put UITextViewDelegate inbetween the <> in the .h and in the method ive put return YES; at the bottom, what else?

Works fine for me:

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {
	
	NSLog(@"%@",text);
	
	return YES;
}

Did you set the delegate to self?

myTextView.delegate = self;

Thanks for that guys. It's always the simple things.
