使用 UIGuesture 使用 UITextview 调整 UIImageview 的大小

Question

I'm new in Iphone. I have an UITextView inside a UIImageView . Now I need to dynamically resize the UIImageView so that its textview also change its size dynamically. Moreover I can move this UIImageView with UITextView around the screen. If any one knows this using UIGuesture please help me.

Any help would be appreciated

1. If you are looking at resizing the UIImageView object, look at the UIPinchGestureRecognizer . It will have a property called scale that you can use to change its size.
2. As for the UITextView object that is the subview, you can look at autoresizingMask property inherited from UIView . Set it appropriately so that the text view scales in response to its super view.
3. For moving the image view, you can use the UIPanGestureRecognizer . You can get the translation using translationInView: . Use this to modify the center of the image view object. This should move the image view as you drag your finger around.

I hope you've gone through the guide . Let us know if you face problems implementing this and put some code so that we can guide you in the right direction.
