iPad Orientation Control help

cvp

@mcriley821 you're right. I 🤐 and 😰

stephen

Wow.. ok let me go over this data and ill see what i come up with. im still learning ObjC/Swift. Thank ya'll so much for your input and time im off to crash Pythonista a few times lol i hope we can get this because it would be nice for everyone to have this ability without XCode..

Apple said:

@property(nonatomic, readonly) UIInterfaceOrientation preferredInterfaceOrientationForPresentation;

Documentation

Just to make sure im understanding properly lol..

we use preferredInterfaceOrientationForPresentation with 2 or more UIInterfaceOrientation set on our UIViewController to limit rotation but allowing rotation to differ from UIStatusBar. and if we dont set this property it will keep the UIViewController set to the current UIInterfaceOrientation of UIStatusBar UIInterfaceOrientation..

Instead of trying to make the View's rotation differ from the status bar. why dont we just control the rotation of UIStatusBar itself? or is that where iPadOS has the issue of ontrolling orientation of apps that supports split-screen multitasking.

@cvp you cannot monkey patch an objc object, without using the objc runtime (swizzleing). Monkey patching just affects calls in python -- when the system calls a selector it doesn't know anything about the python attribute.

There is a way to swizzle in objc, though as I recall, swizzling a single instance is tricky.

@stephen wow 🤔🤯🤕🤒

cvp

@JonB Thanks for your explanation.

lol i just read what i put lol it sure is a bit of a mouth full 😂🤣

stephen

@JonB would you happen to know of any good tutorials/walkthroughs/guides i can checkout on objc_util..? im kinda grasping it but there just somthing missing for me to fully take her home...

stephen

😂 just found this while looking through my list of view controller members lol

about died

stephen

😓😴 im at a loss.. i tried:

setInterfaceOrientation
shouldAutorotateToInterfaceOrientation
preferredInterfaceOrientationForPresentation
viewControllerForRotation().setInterfaceOrientation_
setModalPresentationStyle
window_willRotateToInterfaceOrientation

the list goes on for a bit lol

ill get no errors but also nothing changes

JonB

Did you implement @mcriley821 's code, along with the alloc().init()? I haven't but mcriley says it works...

cvp

The gist in one of my posts used @mcriley821 's code.

The method works but not what @stephen wants.
Perhaps, the used ViewController is not the good one.

stephen

@JonB @cvp ya iv been mesing with it for just a min and i cant seem to get it to lock, force rotate or anything lol

cvp

@stephen you're right. I don't know how to do and that's the reason why I saidthat I let YOU go on 😅

all good i even tried the one JonB mentioned and nothin

JonB

In that case the best option may be to implement a callback on the layout method to re-rotate the view. This could maybe be implemented with a simple Transform.rotate.

When I detect a rotation from ui.View. layout(self) from the resizing i can just rotate and resize my View object? only negative part is the status bar being in the wrong place? if so id say thats a good compromise lol

JonB

Im thinking:

Root view - uses flex, to detect layout.
-> rotated_view. Fixed size. Uses a Transform.rotation to back out the orientation.
-> everything else is a subview of rotated_view

You can get orientation with a bit of objc, or by using a 1 pixel webview and some JavaScript.

stephen

@JonB

to get orientation if always did:

def Orientation():
	return PORTRAIT if get_screen_size()[0] < get_screen_size()[1] else LANDSCAPE

JonB

If you want to be able to detect upside down landscape etc, versus just screen size, you'd have to use objc, or a webview and some JavaScript to get the viewport rotation.

In objc,, you can get the view controller, then use
[UIViewController interfaceOrientation]

Or,

[[UIDevice currentDevice] orientation]

Or, I believe there is something that grabs the status bar orientation.
