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

😓😴 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.

@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

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.

awesome thank you! this objc_util stuff is interesting.. lol im starting to get the hang of it. i do want to askmone thing though..

ive been using inspect.getmembers() to list fields and methods.. is this good option or is there a better way?

This is a good way to see a complete list of available classes (that is, from loaded frameworks) and their methods. Tapping a method name installs a swizzle to log all calls to that method -- useful for figuring out how to call an omz custom method for instance. Don't tap a method name unless you want said logging.

For viewing instances, your method works. Also, You can use

https://github.com/jsbain/viewbrowser/blob/master/getobjcprops.py

To get all properties/values of an objc instance. There is a table view delegate to show as a table. I probably need to create a workspace browser that ties together the viewbrowser objc oject browsing functionality...

@JonB

Awesome! That would be a wonderful asset 😀
