iPad Orientation Control help

[mcriley821]

Yea add an .alloc().init(). The anti-spam bot won’t let me add it on there. Sorry for the confusion

[cvp]

@mcriley821 yes, I already did it

[cvp]

@mcriley821 I tried this script. I'll let @stephen go on 😇
Thanks for your help. I'm happy we have now a new ObjectiveC guru because I only use it with a lot of tries.
Put in gist because refused as spam???

@jonb @mcriley821 I don't understand why my monkey patching was not good because the method was also called, proved by the print.

[mcriley821]

@cvp I’m no guru by any means lmao. It takes many crashes for me before I get something working. I’m steadily learning though.

My only guess on why monkey-patching didn’t work is because we already alloced and inited vc as a regular UIViewController and didn’t create another instance after overwriting the class method. But honestly I’ve never done monkey-patching so I’m not positive what I’m talking about

[cvp]

@mcriley821 But I was overriding an instance method, not a class method. And it worked because the def was called.

[cvp]

@mcriley821 I just tested with my old code and modal style 0, and it works in the same way as your code with the new objc class. The only difference is that the _cmd 2nd parameter is not accepted.

[mcriley821]

@cvp if you do

print(vc.preferredInterfaceOrientationForPresentation())

you still get 1, but if you

print(UIViewController.preferredInterfaceOrientationForPresentation())

You get 3.
Your monkey-patch overwrites the UIViewController object. But if you do

vc.preferredInterfaceOrientationForPresentation=preferredInterfaceOrientationForPresentation(vc)

The print has an error 'int object is not callable'.
Maybe it thinks the method is an attribute, and instead of overwriting the function it just makes an attribute

[cvp]

@mcriley821 you're right. I 🤐 and 😰

@cvp @JonB @mcriley821

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.

[JonB]

@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.

[cvp]

@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

attentionClassDumpUser_yesItsUsAgain_althoughSwizzlingAndOverridingPrivateMethodsIsFun_itWasntMuchFunWhenYourAppStoppedWorking_pleaseRefrainFromDoingSoInTheFutureOkayThanksBye_

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.
