UIView.drawribesg
02/07/2020, 4:05 PMIt’s exposed to Kotlin as an
@ObjCMethod externalUIViewribesg
02/07/2020, 4:06 PMSo obviously this does not work

02/10/2020, 9:30 AMIt doesn’t seem to work, no. But as the IDE doesn’t help I’m not sure what I write is correct anyway. It says it overrides nothing, as I expected

02/10/2020, 9:32 AMThe function I want to override:
@kotlinx.cinterop.ObjCMethod public external fun platform.UIKit.UIView.drawRect(rect: kotlinx.cinterop.CValue<platform.CoreGraphics.CGRect>): kotlin.Unit { /* compiled code */ }ribesg
02/10/2020, 9:39 AM@louiscad what makes you think it should work? Did you manage to make it work in some case already? https://kotlinlang.org/docs/reference/native/objc_interop.html#category-members

02/10/2020, 9:43 AMOh, that's a category member! I don't recall for which function I made it work, but it seems that is a current limitation of Kotlin/Native. @kpgalligan do you know why there is this limiation, and if there's a workaround?

While the use of drawRect is common, it’s a practice that has been discouraged since at least 2002/2003Apparently you should ‘now’ (and for the last 18 years) use drawLayer, which can be overridden apparently. But yeah the question’s still there, will we be able to override these at some point?
