Can someone explain if multi-touch zoom is supposed to work for UITextView or UIScrollView?

The UIScrollView class provides support for displaying content that is larger than the size of the application’s window. It enables users to scroll within that content by making swiping gestures, and to zoom in and back from portions of the content by making pinching gestures. By adding your UITextView to a UIScrollView you can implement muti-touch zoom.

I have searched SO and found no simple way to zoom in on a UITextView or UIScrollView. I was led to this link which says I need to write custom views to overwrite the existing ones in order to be able to zoom in to a textView. I can not believe this and would like someone to please let me know if there is a simple way to zoom in and zoom out using multi-touch on a UITextView or a UIScrollView.

I tried setting the options in the IB to enable multi-touch as well as the max zoom. But this does not work. Please advise.

Still no joy getting multi-touch zoom to work on a textView. Anyone out there can recommend a sample that shows this working? – jroyce Feb 20 at 0:37 Does zoom work with textView?

Is this such an obscure question that no one has a response? Please help... – jroyce Mar 1 at 18:01.

My UITextView is inside of the UIScrollView currently and I couldn't get it to work. I tried making my UITextView much larger than my UIScrollView in the IB but that didn't do it either. Any suggestions?

– jroyce Feb 1 at 3:15 1 It's possible that your UITextView is becoming the first responder when you tap in the UIScrollView. You will need to differentiate a single tap (edit the text view) with a multitouch (zoom in or out). – ibeitia Feb 1 at 3:18 Hmmm ok, how do I go about setting it up correctly?

– jroyce Feb 1 at 3:27 So is it true that the multi-touch zoom feature should work with text in a UITextView? – jroyce Feb 1 at 3:28 Multitouch should work with anything inside a UIScrollView. – ibeitia Feb 1 at 5:25.

I am resolving to answer this question myself with the assumption that this is not possible at this time. With a textArea I have found no way to zoom in on the text. I have not found any tutorial or example that shows this is possible.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
