Retain the resolution of the label after scaling in iphone

I am having a开发者_运维技巧 label in a view.After scaling the view, the label looks little blurred,the resolution is lost.How to retain the resolution after scaling.

Here is my code for scaling

secondView.transform = CGAffineTransformIdentity;
[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:1.0];
secondView.transform = CGAffineTransformMakeScale(2 ,2);
[UIView commitAnimations];
[self.view bringSubviewToFront:secondView];

I set the ContentScaleFactor property of the label to retain the resolution of the label after scaling .

[label setContentScaleFactor:2];

Create a label of big size itself, scale down using transformations when you add it to the view. So at the run time when the view will scaleup the label's resolution will not be lost.

This is one of the approach.

Thanks
