Autolayout Constraint – Keyboard

by

Try it this way: self.keyboardHeight.constant = -height; [self.view setNeedsUpdateConstraints]; [UIView animateWithDuration:animationDuration animations:^{ [self.view layoutIfNeeded]; }]; Remember this pattern because this should be the correct way to update constraint-based layouts (according to WWDC). You can also add or remove NSLayoutConstraints as long as you call setNeedsUpdateConstraints after.

Leaving inputAccessoryView visible after keyboard is dismissed

by

It’s done like this: Assign your UIToolbar to a property in your view controller: @property (strong, nonatomic) UIToolbar *inputAccessoryToolbar; In your top view controller, add these methods: – (BOOL)canBecomeFirstResponder{ return YES; } – (UIView *)inputAccessoryView{ return self.inputAccessoryToolbar; } And then (optionally, as it usually shouldn’t be necessary), whenever the keyboard gets hidden, just call: [self … Read more

UIKeyboardBoundsUserInfoKey is deprecated, what to use instead?

by

I played with the previously offered solution but still had issues. Here’s what I came up with instead: – (void)keyboardWillShow:(NSNotification *)aNotification { [self moveTextViewForKeyboard:aNotification up:YES]; } – (void)keyboardWillHide:(NSNotification *)aNotification { [self moveTextViewForKeyboard:aNotification up:NO]; } – (void) moveTextViewForKeyboard:(NSNotification*)aNotification up: (BOOL) up{ NSDictionary* userInfo = [aNotification userInfo]; // Get animation info from userInfo NSTimeInterval animationDuration; UIViewAnimationCurve animationCurve; … Read more

Change text of “Return” keyboard button

by

Unfortunately, you can change “Return” into only one of these predefined labels with the returnKeyType property: Return (default) Go Google Join Next Route Search Send Yahoo Done Emergency Call Continue (as of iOS 9) So maybe you should choose “Next” if a data entry kind of activity is what you’re after.
