滚动UITableView时拉起键盘并与tableView一起滚动

Question

To add panning behaviour to the keyboard, I am using DAKeyboardControl . It works just fine (after modifications) for panning behaviour to close the keyboard.

How do I make the keyboard appear if the user tries to scroll downwards (finger pan in up direction) at the end of the UITableView . To be more specific, I am looking for behaviour similar to the Facebook Messages app, where, if you scroll up the keyboard appears, with panning, and scrolls with the table.

EDIT : It seems I am not clear about what I want. I wish to move the keyboard along with the scrollview ( UITableView ). In the following image, I am panning the keyboard along with the table. The table is already scrolled to it's bottom, and if I try to scroll down any further the keyboard begins to appear. My finger, meanwhile, is in the middle of the table.

Answer 1

This effect can be achieved by setting the scrollview's keyboardDismissMode to UIScrollViewKeyboardDismissModeInteractive and then in scrollViewDidScroll: calling [textField becomeFirstResponder]; . Because you are in the middle of scroll, the keyboard will respect the keyboardDismissMode property and interactively appear. Drop the DAKeyboardControl ; it's outdated.

Answer 2

You need an element such as UITextView and then, detect the scroll (for example, using any of the UIScrollView delegate methods). Once scrolled, call becomeFirstResponder on the text view.

Answer 3

add this in .h file…

@property (nonatomic, assign) CGFloat lastContentOffset

And add this in your .m file...

- (void)scrollViewDidScroll:(UIScrollView *)sender 
{
   if (self.lastContentOffset > scrollView.contentOffset.y)
   {
       [textField becomeFirstResponder];
   }
   else if (self.lastContentOffset < scrollView.contentOffset.y) 
   {
       [textField resignFirstResponder];
   }
   self.lastContentOffset = scrollView.contentOffset.y;

}

Hope this will do the trick, haven't tested it...
