Resizable UILabel which scrolls across the screen

[domness]

Right, I'm trying to get a label with text in it (done already obviously), which scrolls across the screen.

The text that is input into the label is done by a UITextField and a UIButton. This updates fine.

But I'm trying to get the UILabel to resize accordingly to the amount of text input, so that the WHOLE lot of text scrolls across the screen.

This is the code I have at the moment for the scrolling label:

[lblMessage setText: txtEnter.text];

	
	CABasicAnimation *scrollText;
	
	scrollText=[CABasicAnimation animationWithKeyPath:@"position.x"];
	scrollText.duration = 3.0;
	scrollText.repeatCount = 10000;
	scrollText.autoreverses = NO;
	scrollText.fromValue = [NSNumber numberWithFloat:500];
	scrollText.toValue = [NSNumber numberWithFloat:-120.0];
	
	[[lblMessage layer] addAnimation:scrollText forKey:@"scrollTextKey"];

The problem is, sometimes is starts scrolling in the middle of the screen, and sometimes vanishes before it has fully gone acrosss.

It also cuts of text due to the label being one size.. I don't know how to change this.

Thanks in advance.
