This allows `FLEX` to be linked statically to a binary that has `-Wstrict-prototypes` enabled (for example in CocoaPods without `use_frameworks!`.
Changes:
- Apply `void` to all the empty function/block declarations that don't take arguments.
- Apply `SEL`/`UIImage *` to the others that actually take arguments.
- Remove `CLANG_WARN_STRICT_PROTOTYPES = NO` since the default is enabled.
Other changes:
- Editor/caller view controllers use a toolbar for the call/set button now
- FLEXNavigationController adds the Done button to it's root view controller instead of FLEXExplorerViewController
- FLEXExplorerViewController now overrides presentViewController: and dismissViewControllerAnimated: to toggle its window's key status instead of using new methods to do it
- Adds a 't' simulator shortcut to quickly present an explorer screen for testing
There was a lot of code duplication between the property and ivar editor classes. This fixes that.
- Renamed: FLEXFieldEditorViewController → FLEXVariableEditorViewController
- Renamed: FLEXMutableFieldEditorViewController → FLEXFieldEditorViewController
- Collapsed FLEXPropertyEditorViewController and FLEXIvarEditorViewController into their parent class, FLEXFieldEditorViewController
- Property/ivar editor now takes a FLEXProperty/FLEXIvar
- Property/ivar editor initializer is failable based on editability of property/ivar
- FLEXMethodCallingViewController now takes a FLEXMethod
- Argument input views will now generally allow editing of a nil value
