    Calling Objective-C functions from lua

    Hi everyone,

    I'm trying to mask an image within the HotWax (BhWax) plugin (iOS platform).
    I have tested different ways of implement some calls to the corresponding iOS functions (Objective-C) but without success.
    How could these functions to be called from Lua ?

    The piece of code to be "translated" is:

    "
    UIImage *inputImage = [UIImage imageName:@inputImage.png];

    CGImageRef maskRef = [UIImage imageNamed:@mask.png].CGImage;

    CGImageRef mask = CGImageMaskCreate(CGImageGetWidth(maskRef),
    CGImageGetHeight(maskRef),
    CGImageGetBitsPerComponent(maskRef),
    CGImageGetBitsPerPixel(maskRef),
    CGImageGetBytesPerRow(maskRef),
    CGImageGetDataProvider(maskRef), NULL, false);

    CGImageRef masked = CGImageCreateWithMask([inputImage CGImage], mask);
    "

    Btw, the first one in Lua can be called like this:

    "
    UIImage:imageWithContentsOfFile(getPathForFile("inputImage.png"))
    "

    Thanks.
