There is no reason to not mention the NSOpenSavePanelDelegate protocol
that AquaFilePickerDelegate implements.
The way we used objc_msgSend() caused a crash or hang. (I saw both,
depending on whether the code was built for debugging or not). For
some reason we used to cast it to a function with variadic parameters
like:
reinterpret_cast<id (*)(id, SEL, ...)>(objc_msgSend)(
m_pDialog, @selector(setDelegate:), m_pDelegate);
This does not work in arm64 code on macOS. (See
https://developer.apple.com/documentation/apple_silicon/addressing_architectural_differences_in_your_macos_code?language=objc
, the "Don't Redeclare a Function to Have Variable Parameters"
section.)
We could have replaced the ellipsis with the actual type of the first
real parameter in this call, or just "id" would have worked fine. But
it is much simpler to just do what we mean directly:
[m_pDialog setDelegate:m_pDelegate];
I need to look through the code for other places where we have used
objc_msgSend() in a similar fashion.
