Answer 1

Step 1. Get event when user touches inside textview (You can get that by UITextView's Delegate (startEditing delegate))
Step 2. Add a UILabel on ur view giving position where user touches in textview and giving text as that of textview and giving clear color as backgroundcolor. (Do this inside delegate of textview)
Step 3. Inside touches move of ur view change the positions of ur label dynamically according to touches.
Step 4. When user moves its touches till dropping textview delegate will be called check there if(textview==droppingtextview) then put draggingtextview.text=label.text. and remove label from superview.
