I have a UIScrollViewand in the UIScrollViewI have UITextFeild's in that UIScrollView. 私の問題は、をクリックした後、UITextfFeild設定UIScrollViewしたものよりも小さくなることです。
私は自分を設定しましたUIScrollView：
-(void) viewDidAppear:(BOOL)animated {
myScrollView.contentSize = CGSizeMake (320,800);
}
をクリックすると、UITextfeild800UIScrollViewから約 500 に小さくなりますか?
