- [LKImageRequest generateIdentify] 判断 processorList 元素个数为 0 后是否应该进行 return？

[PipeDog]

源码为

- (void)generateIdentify
{
    if (self.processorList.count == 0)
    {
        self.identifier = self.keyForLoader;
        // return; ???
    }
    self.identifier = [NSString stringWithFormat:@"%@:%@", self.keyForLoader, [LKImageProcessorManager keyForProcessorList:self.processorList]];
}
