The iphone pops up the keyboard and the text box automatically moves up.

1.
Let class inherit Uitextviewdelegate


Uitextview *inputtextview;
Uiscrollview * _scrollview;


2. Create the ScrollView in the INIT function first
_scrollview = [[Uiscrollview alloc] Initwithframe:cgrectmake (0, 0, 320, 416)];
[Self.view Addsubview:_scrollview];




Inputtextview = [[Uitextview alloc] Initwithframe:cgrectmake (Nstarty, 290, 110)];
[Inputtextview Setfont:[uifont systemfontofsize:15];
Inputtextview.backgroundcolor = [Uicolor Clearcolor];
Inputtextview.delegate = self;
Inputtextview.returnkeytype = Uireturnkeydone;
[_scrollview Addsubview:inputtextview];
