Load cell in UICollectionViewController, cell is XIB hybrid development, there are UITextFiled. When you click UITextFiled, the keyboard pops up, the entire View moves up, the clicked UITextFiled is moved out of the interface. Seek help: There is no way to turn off the keyboard pop-up View automatically move up. Or who knows what's wrong with it?
-(void)viewWillAppear:(BOOL)animated {
} I found a solution: to implement this method and not call [super viewWillAppear:animated] can be solved.
