Change UITableViewCell size

Objective-C

I have a UIView in a static UITableViewCell. I added a height constraint to the view. I think, the correct way to animate the change of a views height would be like this:

self.myViewsHeightConstraint.constant = 100; // Coming from 0 and vice versa
[UIView animateWithDuration:0.3f animations:^{
    [self.view layoutIfNeeded];        
}];

I set the tableView row height to:

tableView.estimatedRowHeight = 40;
self.tableView.rowHeight = UITableViewAutomaticDimension;

Now I need to update the cells height. So I think a begin/endUpdate would be proper. When the veiw and the cell animate its heights change, they aren't synchronized, so because they don't animate the exact same time, I get the following warning:

Unable to simultaneously satisfy constraints.
    Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)

    "<NSLayoutConstraint:0x7f8d62cea010 tagResultTableView:0x7f8d62d901a0.top == UITableViewCellContentView:0x7f8d62d8fd50.topMargin - 8>",
    "<NSLayoutConstraint:0x7f8d62cf0760 V:[tagResultTableView:0x7f8d62d901a0]-(8)-[UILabel:0x7f8d62d2e2e0'Limit: Up to 5 tags']>",
    "<NSLayoutConstraint:0x7f8d62cf0800 UILabel:0x7f8d62d2e2e0'Limit: Up to 5 tags'.bottom == UITableViewCellContentView:0x7f8d62d8fd50.bottomMargin>",
    "<NSLayoutConstraint:0x7f8d62f726d0 'UIView-Encapsulated-Layout-Height' V:[UITableViewCellContentView:0x7f8d62d8fd50(32)]>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x7f8d62d15670 V:[tagResultTableView:0x7f8d62d901a0(107)]>

If my logic is correct, how can I animate them the exact same time. Or how can I animate them so I won't get the error?
