I have a small problem with NSInvocation, im setting an invocation up
like this:
// setWidth: is a method defined by self.
NSMethodSignature* sig = [LayoutControl
instanceMethodSignatureForSelector: @selector(setWidth:)];
NSInvocation* incovation = [NSInvocation
invocationWithMethodSignature:sig];
[invocation setSelector: @selector(setWidth:)];
[invocation setTarget:self];
whenever i try and invoke it, i get this error message:
2004-11-24 16:04:04.970 Cocode[4943] *** -[NSInvocation copyWithZone:]:
selector not recognized
Whats going n here and how can i fix it? Can my invoced method have non
"NS" types?
thanks
Alex
