Obj-C - UITapGestureRecognizer doesn't work after UIView is animated?

Question

This is so strange - for some reason, when my UIView animates up (once I tap my UITextView), my UITapGesture doesn't execute? E.g. tapping anywhere on the view once the view is animated and UITextView is active doesn't dismiss the animated view? However if I tap anywhere on the view BEFORE it animates, UITapGesture executes just fine - why is this?

ViewController.m

- (void)viewDidLoad {
    [super viewDidLoad];
    self.replyField.delegate = self;

    UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self
                                                                          action:@selector(dismissKeyboard)];
    [self.view addGestureRecognizer:tap];

}

-(void)dismissKeyboard {

    [self animateTextView:NO];

}



- (void)textViewDidBeginEditing:(UITextView *)textView
{

    [self animateTextView: YES];

}


- (void)textViewDidEndEditing:(UITextView *)textView
{
    [self animateTextView:NO];


}


- (void) animateTextView:(BOOL) up
{
    const int movementDistance = 206; // tweak as needed
    const float movementDuration = 0.3f; // tweak as needed
    int movement= movement = (up ? -movementDistance : movementDistance);
    NSLog(@"%d",movement);

    [UIView beginAnimations: @"anim" context: nil];
    [UIView setAnimationBeginsFromCurrentState: YES];
    [UIView setAnimationDuration: movementDuration];
    self.view.frame = CGRectOffset(self.inputView.frame, 0, movement);
    [UIView commitAnimations];


}

I think you should take a look at this link https://stackoverflow.com/questions/1126726/how-to-make-a-uitextfield-move-up-when-keyboard-is-present — trungduc, Nov 02 '17 at 03:23
Mine is a UITextView, not a UITextField... Works differently @trungduc — Brittany, Nov 02 '17 at 03:24
sorry, my bad. But i think they are UiView, and you are using UIView animation. Maybe it will work. — trungduc, Nov 02 '17 at 03:31
When you tap again, then `-(void)dismissKeyboard` is not being called or not? or just it is not animating but this method is being called? — 3stud1ant3, Nov 02 '17 at 03:37
@3stud1ant3 -(void)dismissKeyboard isn't being called. It's almost as if everything outside the UITextView is frozen once it's active. — Brittany, Nov 02 '17 at 03:38
Just a suggestion: From the documentation of `beginAnimations:context:` I learnt this: "Use of this method is discouraged in iOS 4.0 and later. You should use the block-based animation methods to specify your animations instead." — 3stud1ant3, Nov 02 '17 at 03:41
It's a really bad idea to change the frame of a view controller's view. Why not just move the text view? — rmaddy, Nov 02 '17 at 05:14
When the Tap gesture is not working -Check your View UI hierarchy- . check if something is on top or it is misplaced. — Bhumit Muchhadia, Nov 02 '17 at 05:18
@BhumitMuchhadia It doesn't look like anything is on top of it? Also, View is always at he top of the hierarchy? E.g. View > tableview > tableviewcell... ? — Brittany, Nov 03 '17 at 02:48

Once try like,

- (void) animateTextView:(BOOL) up
{

     UIViewAnimationOptions options =  UIViewAnimationOptionAllowUserInteraction;

     const int movementDistance = 206; // tweak as needed
     const float movementDuration = 0.3f; // tweak as needed
     int movement= movement = (up ? -movementDistance : movementDistance);

     [UIView animateWithDuration:movementDuration
                           delay:0.0
                         options:options
                      animations:^{
                                       self.view.frame = CGRectOffset(self.inputView.frame, 0, movement);

                                  }
                      completion:nil];
 }

Animates up but again, view isn't able to be dismissed on tap. Seems everything except the textfield is frozen. — Brittany, Nov 03 '17 at 02:13
