ios11

The following line of code is where our app has suddenly started to crash on iOS 11 / 11.0.1 / 11.0.2 / 11.1.1 / 11.2.2 for some users: UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter]; We've got this in didFinishLaunchingWithOptions . The crash report says: Fatal Exception: NSInternalInconsistencyException Invalid parameter not satisfying: bundleProxy != nil Fatal Exception: NSInternalInconsistencyException 0 CoreFoundation 0x1869b3d38 __exceptionPreprocess 1 libobjc.A.dylib 0x185ec8528 objc_exception_throw 2 CoreFoundation 0x1869b3c0c +[NSException

In my app there is some logic for frameless devices (iPhoneX, Xs Xs max, Xr). Currently it works base on the model of the devices, so, I detect the model by DeviceKit framework. But I want to extend this logic to future frameless devices. Probably in one year we will have some extra frameless devices. So, how can I detect if device is frameless or not? It should cover all current frameless devices and future one. We can not rely on faceID, safeAreaInset, screen height or size. So, then what? You could "fitler" for the top notch, something like: var hasTopNotch: Bool { if #available(iOS 11.0,

I am using a UISearchController and a UISearchResultsController to implement search functionality. MySearchResultsController implements UISearchResultsUpdating and UISearchBarDelegate: override open func viewDidLoad() { super.viewDidLoad() self.edgesForExtendedLayout = []; self.automaticallyAdjustsScrollViewInsets = false; } I display the searchbar in the tableHeader like this in MyTableViewController: - (void)viewDidLoad { [super viewDidLoad]; self.searchController = [[UISearchController alloc] initWithSearchResultsController:self.searchResultsController]; self.searchController

I calculate itemSize dependent on safe area for UICollectionView with horizontal scroll and custom layout. But for iPhone X safe area has different size for different orientation. My question is how should I calculate safe area size for landscape orientation in viewWillTransition function? Or how is it possible to do without this calculation? EDIT To get safe area size without creating any additional views, use this: view.safeAreaLayoutGuide.layoutFrame.size If you want to use viewWillTransition method you can use this: override func viewWillTransition(to size: CGSize, with coordinator:

The html page I made by using canvas becomes different in ios11! When first show in the webview, the page looks fine, but, when it scrolls down and the canvas in it becomes invisible in the viewport, the content in the canvas disappears and never comes back when the page scroll back to top. Does somebody know how to fix this problem or I should just wait until apple fixes it later? Same problem for me. I noticed that if I toggle in Safari Web Inspector any properties of the canvas, it is rendered again. Another similar issue is reported on SO ( Cordova Webview canvas redering bug on recent iOS

I'm trying to understand the difference between the different element introduced in ArKit and their maybe equivalents in SceneKit: SCNNode.simdTransform vs SCNNode.transform . In ARKit, it seems that people use SCNNode.simdTransform instead of SCNNode.transform . How do they differ? simdTransform seems to use column major order, while transform (SCNMatrix4) is row major. How do I convert one to the other? Just transpose? I've the impression that the tracking doesn't work as well if I use transform instead of simdTransform . Is that expected or just an impression? If I set one property, what
