Zoomable scroll View

RabbitFactoryUK · 05-05-2011, 08:17 AM

Hi guys!

I have a simple application that has a tab bar and a navagation controller and the view is with in a scrollview.

Heirarchy:

-Scroll View
- View
-Textview
-ImageView
-Label

How the view does have a lot of information in it but the font size in the text fields and labels is a little small.

How would I go about adding zoom functionality in the ScrollView so that all the elements with in the View increase in size, as you would with say a image or if you were zooming a PDF?

This has been bugging me for ages and any help or links would be appreaciated

Thanks

No need to do this. Increase the font sizes.

Group all the views that you want to be zoomed into a parent UIView. In the scrollview delegate method viewForZoomingInScrollview: have it return this new UIView. Everything inside of it will be zoomed, and you will get the effect you want.
