I’m trying to send messages from a class to one of its subclasses. I have a
method that returns the class I want to forward to. If I use it in the
following manner, it works:
+ (void)logout
{
// subclasses handle it
[[self classToUseForBackend] logout];
}
By setting breakpoints in this method and the subclass I can see that the
message goes where i expect.
If I use it in the following manner, the message is not forwarded to the
subclass with the identical signature. It ends up being re-sent to the
superclass method (i.e. where I’m calling it here) and I get an infinite loop.
+ (NSString *)errorMessageForCode:(NSInteger)errorCode
{
// subclasses handle it
NSString *msg = [[self classToUseForBackend] errorMessageForCode:errorCode];
return msg;
}
Can somebody explain to me why I’m getting this different behavior. Is there
anything I can do to achieve my goal?
