Hi everyone,
I'm trying to subclassing NSButton. For the moment, it is just a
test : my class SBButton has no specific methods.
In IB, I created a SBButton class ans assigned it to a NSButton.
But when I run my test program, I've got :
[Session started at 2005-11-04 20:13:10 +0100.]
2005-11-04 20:13:11.088 ShapedButton[2868] *** -[SBBouton
initWithCoder:]: selector not recognized [self = 0x306810]

ShapedButton has exited due to signal 5 (SIGTRAP).
What did I done wrong ? What does it mean ?
How did you create an instance of your button? Did you use
Interface Builder and create a custom view? Or are you building the
instance programatically?
It looks like you're creating the button from a nib (and thus
initWithCoder is being called).
What exactly is the source to your subclass?
How it's instantiated shouldn't matter, should it? Assuming it's
really a subclass of NSButton (and not NSObject or something)
initWithCoder should be there.
I'd be most interested in the header. _______________________________________________
