问题 I have an iPad app (in C#) with a custom UIView that allows input via touch and Apple Pencil stylus touches. I am trying to integrate support for trackpad/mouse indirect (cursor, or "pointer" as Apple calls it). I got hover working using HoverGestureRecognizer. I got right-click and control-click working using normal touch Began/Moved/Ended/Cancelled events and checking for .type == .indirectPointer and then checking if the control key modifier in event.ModifierFlags is set, or if event

问题 When using PencilKit in iOS 13/iPadOS, how do you change the content in PKDrawing? For example, can I go through all the lines and change the color or width of the lines? Or for selected lines (via lasso)? Or add a straight line in our own code? 回答1: PKDrawing is listed as an Opaque data object. See this Wikipedia Link for an explanation of opaque data object. Unfortunately strokes are not exposed to us. Our only 2 options currently can be found in the docs under Modifying the Drawing.

问题 We were able to detect an iPad device using javascript like this: function isDeviceiPad(){ return navigator.platform.match(/iPad/i); } That worked perfectly in detecting iPad devices, but when we checked from an iPad Pro (10.5 inch) , it does not detect that it is an iPad.

问题 I am building a photo app that uploads photos selected from the devices gallery. The uploads work great in the simulator for iOS13, but when I test on my iPad (iPasOS 13), the uploads always fail with 'Unknown Error' code. The app has permissions to access the gallery (otherwise I wouldn't be able to select images from the gallery before attempting the upload). I am attaching photos of the same build succeeding in iOS simulator and failing on my iPad. Any idea why this could be happening? I

问题 iPadOS 13 now shows a white/grey bar when a WebApp is installed via 'Add to Home Screen' on Safari, even when apple-touch-fullscreen meta tag is added. The bar includes a menu to resize font and request desktop site, but has affected the available screen size so that the users now have to scroll to view the app menu.
