    if ([format compare:@\"json\"] == NSOrderedSame) {
        return [[MHJsonTwitt

The warning is there simply because not every path through the code ends with a return statement which the compiler recognizes as potentially problematic. That said, you probably shouldn't be throwing an exception here and should instead be generating an NSError and returning nil. The differences between exceptions and errors in objective-c are explained here and here.
