UIPopoverPresentationController animate preferredContentSize

I am using UIPopoverPresentationController to present my tableView controller as PopOver. I am able to change its preferredContentSize to tableView contentSize as follows,

- (void)viewDidAppear:(BOOL)animated {
     [super viewDidAppear: animated];
     self.preferredContentSize = self.tableView.contentSize;
}

Here the problem is the contentSize is getting changed immediately which is not looking good. I tried animating it like this but it doesn't work. Any help would be appreciated.

P.S. I tried changing the contentSize in viewWillAppear but it doesn't work and I am using Objective C not Swift.

Solution

  • Try this:

    - (void)viewDidAppear:(BOOL)animated {
     [super viewDidAppear: animated];

     dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(0.1 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{
         self.preferredContentSize = self.tableView.contentSize;
     });
}
