<PRE>Hello,
|
||
|
|
|
||
|
|
I want to override +(bool)[NSObject respondsToSelector:sel].
|
||
|
|
><i>
|
||
|
|
</I>
|
||
|
|
The signature above is for a static method, not an instance once (+ vs - in
|
||
|
|
the signature).
|
||
|
|
|
||
|
|
|
||
|
|
><i> My best guess is this, but the app crashes inside the call to the base
|
||
|
|
</I>><i> method.
|
||
|
|
</I>><i>
|
||
|
|
</I>><i> [Export("respondsToSelector:")]
|
||
|
|
</I>><i> public override bool RespondsToSelector (Selector sel)
|
||
|
|
</I>><i> {
|
||
|
|
</I>><i> bool result = base.RespondsToSelector(sel);
|
||
|
|
</I>><i> return result;
|
||
|
|
</I>><i> }
|
||
|
|
</I>><i>
|
||
|
|
</I>
|
||
|
|
Do not use the [Export] if you are overriding an existing method that is
|
||
|
|
already defined.
|
||
|
|
|
||
|
|
Miguel.
