iOS example crash on real hardware with error "-[RSTView animator]: unrecognized selector sent to instance"

[marysaka]

This was tested against a790eb95b77900ef52d25e1211166787be3bc23a with the example on the repo

It appears to me that RSTView is registered in multiple places of the codebase, those could possibly conflict I suppose?

Cargo.toml:

cacao = { git = "https://github.com/ryanmcgrath/cacao", features = [ "uikit", "autolayout" ], default-features = false }

Ah, yeah, this is an oversight on my part - and why I label iOS as alpha, heh. More people testing it will push things like this to get found and fixed though, so def appreciate this issue being opened.

The core issue is that the APIs used for animation in Cocoa are here, and I simply didn't do the iOS counterpart - it's attempting to initialize animator proxy access with a selector that's not used on iOS.

I'd need to sit down and either stub this out so it's just a no-op on iOS for now, or do the actual work to support basic animations on iOS as well.

[ryanmcgrath]

46 should fix this one it's merged - so closing this for now. Any further comments can go over there.

Thanks for reporting it!

[Miha-Rozina]

Is this supposed to be fixed in 0.3.2? I get the same error. If not, is there a plan on releasing a new version with this fix?

[ryanmcgrath]

I thought I fixed this, but it probably isn’t on crates.io - try the repo code tho.

With the repo code it works with the commit 64908e5. I think I tried the latest commit a few days ago and it also didn't work, but another issue.

I'm trying to publish my crate and with published crates you cannot have git dependencies. Thats why I am asking if its possible to get a new version on crates.io.

[ryanmcgrath]

Ah, sure - I can cut a release tomorrow. Ping me if I don’t get to it.

[Miha-Rozina]

Alright, thanks a lot!

[ryanmcgrath]

@Miha-Rozina there should be a 0.4.0-beta1 on crates.io now. I opted to cut a beta release for the moment since there's some more internal changes lurking and I want to communicate to people that it may be wonky at first, but this should hopefully still unblock you for now. Let me know how it works, thanks!

[Miha-Rozina]

Thanks a lot! I do get a runtime error though, but a different one. I'll open a new issue about it.
