Subclassing uitextview with uialertview

[mramin05]

Hi guys,
In my application I want to implement tweeting function.
For that I want to display a multiline input field in actionsheet for user input message.

I have googled a lot. People says that subclassing will be the best option.
But I could not found any suitable tutorial about that for subclassing uitextview in uiactionsheet.

Please help me with any tutorial or sample code as I am new in ipp development.

Thanks in advance.
