There are a hundred and one proposed solutions out there for how to move
UITextView out of the way of the keyboard during editing — usually, it comes down to observing
UIKeyboardWillHideNotification, or implementing
UITextFieldDelegate delegate methods, and adjusting the frame of the superview, or using
scrollToRowAtIndexPath:atScrollPosition:animated:, but all the proposed solutions I’ve found tend to be quite DIY, and have to be implemented for each view controller that needs it.
I thought I’d put together a relatively universal, drop-in solution:
UITableView subclasses that handle everything.
When the keyboard is about to appear, the subclass will find the subview that’s about to be edited, and adjust its frame and content offset to make sure that view is visible, with an animation to match the keyboard pop-up. When the keyboard disappears, it restores its prior size.
It should work with basically any setup, either a UITableView-based interface, or one consisting of views placed manually.Read More
