    if(self.visibleNodes.count==0){
        // NOTE:这里之所以没有采用跟 insertRowsAtIndexPaths 一样的处理方式，那是因为，本身ASD的“bug"。因为如果在reloadDataWithCompletion的回调中后立马获取visibleNodes，这时候获取到的还是0。
        [self reloadDataWithCompletion:^{
            [subArray enumerateObjectsUsingBlock:^(id  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
                [self->insertItemsSubscriber sendNext:obj];

self.visibleNodes.count==0 这个判断需要改成self.view.visibleCells.count==0 这样reloaddata后就会进else了,数据不会重复了
