  • A method hook.

    replacement represents an Objective-C method IMP. It should be a @convention(c) function which takes self: AnyObject and _cmd: Selector as its first two arguments. The remaining argument types should be the argument types of the hooked Objective-C method in order, and the return type should be the return type of the method.

    saveOrig is a closure which will be passed the original method implementation when the hook is applied.

    Declaration

    Swift

    case method(cls: AnyClass, sel: Selector, replacement: UnsafeMutableRawPointer, saveOrig: SaveOrig)
