UIAlertController Unable to satisfy constraints

Question

I am converting all my UIActionSheet and UIAlertView with UIAlertController.

My problem is when I try to present a UIAlertController of style ActionSheet. Here is my code :

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Title"
                                                               message:@"My message"
                                                        preferredStyle:UIAlertControllerStyleActionSheet];

UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:nil];
[alert addAction:cancelAction];

UIAlertAction *OKAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil];
[alert addAction:OKAction];

UIAlertAction *destroyAction = [UIAlertAction actionWithTitle:@"Destroy" style:UIAlertActionStyleDestructive handler:nil];
[alert addAction:destroyAction];

UIPopoverPresentationController *popPresenter = [alert popoverPresentationController];
popPresenter.sourceView = self.view;
popPresenter.sourceRect = self.view.bounds;

[self presentViewController:alert animated:YES completion:nil];

Here is the error :

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:0x7c00ab40 H:[UIView:0x7c0764c0(304)]>",
    "<NSLayoutConstraint:0x7b6c7f80 _UIAlertControllerView:0x7b6c2e50'title'.width >= UIView:0x7b6c3230.width>",
    "<NSLayoutConstraint:0x7ccdfe40 _UIAlertControllerView:0x7b6c2e50'title'.width == UIView:0x7b6efbe0.width>",
    "<NSAutoresizingMaskLayoutConstraint:0x7c33b9d0 h=--& v=--& H:[UIView:0x7c1094e0(0)]>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x7c00ab40 H:[UIView:0x7c0764c0(304)]>

Thank you all.

I also encounter a similar problem in present a UIAlertController of style ActionSheet.

One more possible reason of this is setting the permittedArrowDirections of UIPopoverPresentationController wrongly. In my case, the sourceView of the popover is located at the top, but I have set the permittedArrowDirections to UIPopoverArrowDirectionDown which causes "Unable to simultaneously satisfy constraints" error. The error is gone after I set it to UIPopoverArrowDirectionUp.
