首先说网络慢带来的数据显示问题

可以通过判断请求参数是否一致来刷新tableview。

SJBCategaryModel * categaryModel = self.categarys[CategarySelectRow];

NSMutableDictionary * params = [NSMutableDictionary dictionary];

categaryModel.currentPage = 1;

params[@"a"] = @"list";

params[@"c"] = @"subscribe";

params[@"category_id"] = @(categaryModel.id);

params[@"page"] = @(categaryModel.currentPage);

self.params = params;

[self.manager GET:Main_URL parameters:params progress:^(NSProgress * _Nonnull downloadProgress) {

} success:^(NSURLSessionDataTask * _Nonnull task, id  _Nullable responseObject) {

if (self.params != params) return;

[categaryModel.userArrM removeAllObjects];

for (int i=0; i<[responseObject[@"list"] count]; i++) {

SJBUserModel * model = [[SJBUserModel alloc] init];

[model setValuesForKeysWithDictionary:responseObject[@"list"][i]];

[categaryModel.userArrM addObject:model];

}

categaryModel.total = [responseObject[@"total"] integerValue];

[self.userTableView reloadData];

[self.userTableView.mj_header endRefreshing];

[self checkTableFooterState];

} failure:^(NSURLSessionDataTask * _Nullable task, NSError * _Nonnull error) {

[self.userTableView.mj_header endRefreshing];

}];

上啦加载时，footer显示不一致的问题

if (!self.categarys.count) {

return;

}

SJBCategaryModel * categaryModel = self.categarys[CategarySelectRow];

self.userTableView.mj_footer.hidden = (categaryModel.userArrM.count == 0);

if (categaryModel.userArrM.count == categaryModel.total) {

[self.userTableView.mj_footer endRefreshingWithNoMoreData];

}else{

[self.userTableView.mj_footer endRefreshing];

}

如果请求的数据的数量与总量相等就显示没有更多的数据，若小于总量就显示点击或上拉加载更多的数据。
