I'm getting an Autolayout error when use UIDocumentMenuViewController, the error came when the DocumentMenu is initialized, this is my code:
let importMenu = UIDocumentMenuViewController(documentTypes: doctypes, inMode: .Import) //Error message here
importMenu.delegate = self
importMenu.popoverPresentationController?.barButtonItem = self.addButon;
self.presentViewController(importMenu, animated: true, completion: nil)
And this is the error, and is related to UICollectionViewFlowLayout
the behavior of the UICollectionViewFlowLayout is not defined because:
2016-02-17 13:28:44.538 App[35218:1131869] the item width must be less than the width of the UICollectionView minus the section insets left and right values, minus the content insets left and right values.
2016-02-17 13:28:44.538 App[35218:1131869] The relevant UICollectionViewFlowLayout instance is <_UIAlertControllerCollectionViewFlowLayout: 0x7fbcd5d18e90>, and it is attached to <UICollectionView: 0x7fbcd6823000; frame = (0 44; 10 0); clipsToBounds = YES; gestureRecognizers = <NSArray: 0x7fbcd3e63150>; animations = { bounds.origin=<CASpringAnimation: 0x7fbcd5c80c50>; bounds.size=<CASpringAnimation: 0x7fbcd5c80d40>; position=<CASpringAnimation: 0x7fbcd5c80e40>; }; layer = <CALayer: 0x7fbcd5d19450>; contentOffset: {0, 0}; contentSize: {0, 0}> collection view layout: <_UIAlertControllerCollectionViewFlowLayout: 0x7fbcd5d18e90>.
2016-02-17 13:28:44.538 App[35218:1131869] Make a symbolic breakpoint at UICollectionViewFlowLayoutBreakForInvalidSizes to catch this in the debugger.
I'm using Xcode v7.2 and my Deployment target is 8.0, this happens in iPhone and iPad, someone have faced with this error using UIDocumentMenuViewController?
This is the strange behavior:
EDIT: Also happens on Xcode 7.3
