iPhone Accelerometer Simulator

"The ideea is pretty simple, I made a small http server what serves the x,y,z
acceleration values. I admit I was lazy to write the whole http server so I used
the "simple http server", what is the base of the simulator. You can download
it ..."

"I would also like to implement "Shake for a random page", but cannot figu-
re out how to do the logic for differentiating a shake motion and a x-axis tilt."

SO - How to detect iPhone movement in space using accelerometer?

"I am trying to make an application that would detect what kind of shape you
made with your iPhone using accelerometer. As an example, if you draw a
circle with your hand holding the iPhone, the app would be able to redraw it
on the screen."

forums.bignerdranch.com - Suggestion for next edition of book

"iPad, iPhone 4 and iTouch 4th gen. all have 12-bit resolution for their ac-
celerometer data. Legacy devices have an 8-bit resolution. Something to
consider if your filters are causing issues on older devices."

Parade of Rain - Gyroscope all the way!

"When you calibrate a device off of the accelerometer there is a ‘gymbal
lock’-esque problem when the device is 100% vertical. Any horizontal tilt
cannot be detected because you’ve lost this degree of freedom since one
of your tilt axis is aligned with gravity (what the accelerometer works off
of). When the gyroscope was announced I naively thought, “Hey we can
probably make the perfect tilt controls now that work in any position!” I
got the ‘any position’ part down, but it was far from perfect."

"For 2016, skip down to the stackoverflow.com/a/36575423/294884 . As with
many computing topics, API details change over the years. With autolayout
and so on, the older answers here (which were superb at the time) are not
right now."

r - https://old.reddit.com/r/iOSProgramming/comments/az6gbn/starting_to_go_crazy_how_do_you_present_a_view/

Starting to go crazy, how do you present a view controller, allow it to rotate to landscape, but not have the presenting view controller rotate as well? Won't work with form sheet or custom presentations.


So while not necessarily the cleanest, the end result speaks for itself, and it's transparent to the end-user, so I'd consider that a success! The tl;dr is to do the window nesting solution from Update 2 (by @donbytqi) and then reset the orientation when you dismiss the nested view controller with the solution in Update 3. So I think that should do it, unless I'm overlooking something!
Tested on iOS 11 and iOS 12.

apple - UIFeedbackGenerator

"Haptic feedback provides a tactile response, such as a tap, that draws
attention and reinforces both actions and events. While many system-provided
interface elements (for example, pickers, switches, and sliders) automatically
provide haptic feedback, you can use feedback generators to add your own
feedback to custom views and controls."
