apple pencil charging

I'm trying to use the Apple Pencil pressure values to draw a line of varying thickness. I find that the pressure spikes erratically, often showing full-force at the very end of a stroke, when actually there is no touch. Also the very beginning of a line reports as much higher pressure that quickly drops to something much smaller. And occasionally in the middle of a line when I am drawing lightly, I'll get one or two touches that are spiked really high also.Is this a common thing? How do you prevent it? I will probably just start filtering the pressures and maybe tossing ones that vary drastically from one point to the next, but it should not be doing this, should it?

Hello,I am trying to make a web app that uses the pencil and finger input simultaneously. However, I have found that whenever the pencil is on the screen, no new touch events can occur with the fingers. This is true the other way around as well. I have tried using PEP pointer events and I'm still running into the same issue. Does anyone know if there is a fix for this? Or some framework I can use to get around this? Thanks!

I talked with Apple Support, and they think that iOS 12 may not recognize the Apple Pencil. The iPad Pro sees the device and charges, but doesn't write. Any ideas?

I want to use Apple Pencil in Safari via pointerEvents, but it seems not working properly. Sometimes it does not fire pointer event when I tapped rapidly. I found similar issue in here - https://stackoverflow.com/questions/64314226/ipados-14-apple-pencil-fast-tapping-not-working-html-javascript-ontouchstart/64316781#64316781 and using touch event seems workaround this, but I'm confused this is a bug or intended. If it's intended, how to detect Apple Pencil via touch(or pointer) event? Or is there any solution without these events? Thanks.

Hello.There were several similar questions, but I did not get an accurate reply.Let me ask it like below.Now I am planning to release that I am providing as a managed service to B2B clients.My app has only free version for my customer, APP is 3D viewer from CAD data.I can imagine customer can handle 3D data with iPhone and iPad.One of my business model options is number of downloads. it is not to charge users of the app for downloads, but instead to limit the number of downloads.Here is Question.In case of this, will Apple charge me the standard 30% commission on the fees?Is it possible to charge usage fees with my own billing method such as bank transfer and cash, credit card?Normally, I can think many company handle it by themselves.I don`t think Amazon pay 30% back margin to Apple whenever their customer buy goods.I am saying again. APP is just 3D Viewer. There is no bill system in App.Please have a check and reply it to me.

Apple pencil force calculation doc:https://developer.apple.com/documentation/uikit/touches_presses_and_gestures/handling_stylus_based_input/computing_the_perpendicular_force_of_a_stylus,indicates a division of a measured force by the sine of the attitude angle. Shouldn't this be multiplication?Thanks in advance

I am experiencing increasing lag in calls to touchesMoved / touchesEnded with UIViewConrtoller when simultaneously moving one finger on screen while same time moving Apple Pencil.Xcode 8.0 beta 6.Ipad Pro 9.7 running iOS 9.3.5.Easiest repro is to create a new project, choose Game template, Objective-C language and Metal as game technology.Then add these lines to GameViewController.m before viewDidLoad (for example):static int counter = 0;- (void) touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{ printf( touchesBegan %in, counter++ );}- (void) touchesMoved:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{ printf( touchesMoved %in, counter++ );}- (void) touchesEnded:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event{ printf( touchesEnded %in, counter++ );}Now, if you run the app and move one or more fingers on screen, you get plenty of touchesMoved event with increasing counter.When you lift your fingers, you'll get touchesEnded event immediately. Same hap

I'm looking for a new very accurate stylus for my iPad Mini. Will the Apple Pencil work on all iOS devices or is it exclusively made for the iPad Pro. If it won't work, what are some good (and accurate) styluses for precision note taking?

I want to create a brush similar to a fountain pen, with a three-dimensional feel to the strokes and a distinct tip. Alternatively, is it possible to achieve this by modifying the configuration parameters of a fountain pen brush?
