Hide input Toolbar in JSQMessagesViewController

I am using JSQMessagesViewController for my chat application. When there is no internet activity, I would like to hide the inputToolbar

I tried this but it doesn't work:

    self.inputToolbar.frame.size = CGSize(width: 0,height: 0)

When I installed this, it was gone in less than a second:

    self.inputToolbar.preferredDefaultHeight = 0

Any ideas how to do this? Perhaps disabling the Input Toolbar might also be good enough.

Instead of removing from the supervisor and adding it as a subview, why not just use:



[self.inputToolbar setHidden: YES];

I have found the best solution that has no side effects.
You can make actions in the class a descendant of the JSQMessagesViewController class.

1. Make this base class method available to you:

@interface JSQMessagesViewController ()
- (void)jsq_setCollectionViewInsetsTopValue:(CGFloat)top 
                                bottomValue:(CGFloat)bottom;
@end

2. override the parent implementation method (called resizing):



- (void)jsq_updateCollectionViewInsets {
    CGFloat topInset = self.topLayoutGuide.length + self.topContentAdditionalInset;
    CGFloat bottomInset = 0.0;
    [self jsq_setCollectionViewInsetsTopValue:topInset bottomValue:bottomInset];
}

3. Make a note of how to hide the Input Toolbar permanently:

- (void)hideInputToolbar {
    self.inputToolbar.hidden = YES;
    [self jsq_updateCollectionViewInsets];
}

4. Enjoy!

It turned out that this would work:

override func viewDidLoad() {
    super.viewDidLoad()
    self.inputToolbar.removeFromSuperview()
}
