hello everybody. i am creating a dropdown button in my app. Like a pop-up control which is available in webapps. so when i click on a button, a new uiview containing a pickerview appears. i user beginanimations and commitanimations for dispalying and hiding the uiview. the new uiview is half the size of the scrollview.
I want that whenever the new uiview appears, the size of the scrollview should alter so that the i can scroll through the entire view. something like, when a keyboard appears, we reassign the size of scrollview, so that we can scroll entire view.
So how will i know, when the uiview appears. Is there a notification for beginanimations and commitanimations like for keyboard (UIKeyboardDidHideNotification)
thnx in advance.
