Answer 1

After searching hours i am found one way

-(IBAction)enableScrollButtonPressed:(id)sender{
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
    self.myTextView.scrollEnabled = YES;
    [self.myTextView setText:self.myTextView.text];

    self.myTextView.layoutManager.allowsNonContiguousLayout = false;

});

}

-(IBAction)disableScrollButtonPressed:(id)sender{

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
    self.myTextView.scrollEnabled = NO;
});

}

condition for that is you need to scroll first then you it will work perfectly

Means when disable scroll button is tapped textview should be scrolled at some position must not to at default position
