using on-screen keyboard on iOS crashes in event poll

[ronaaron]

I've almost got my app running on iOS now, but there's one problem.

In text entry fields, I call SDL_StartTextInput() and the on-screen keyboard pops up as expected. But when I press any 'key', the app crashes.

According to XCode this is happening in SDL_PollEvent() (I changed to using SDL_WaitEventTimeout() with the same result).

Thread 1: EXC_BAD_ACCESS (code=1, address=0x10)
A bad access to memory terminated the process.

TBF, I'm compiling SDL2 manually, but I use the configure script except I also add the UIKIT defines so it'll work on iOS. Anyway, I'm unsure how to proceed...

We'll need a call stack to see what's going on here.

Somewhere it looks like the 'committedText' gets messed up. I don't see where, though.

[slouken]

Can you try the latest SDL3 code? We just made a change to reset the committed text when text input is stopped.

[ronaaron]

I can't really drop-in SDL3 right now, but I'll take a look at the diff from 2.30.8 and see if the fix fixes it for me.

[ronaaron]

The changes from 2.30.8 to most recent trunk in uikitcontroller for committedText don't make any difference I can see. I copied the few changes over, no difference.

Okay, can you reproduce this with any of the SDL test programs? checkkeys is a good one to try out.

Are you still able to reproduce it if you use the xcodebuild command-line tool with the xcode project (or build via Xcode's UI) instead of manually adding iOS support to the other build system?

[ronaaron]

Well hell. When I use XCode to build it, the library works. So I guess this should be closed...
