ios - TableView 从 : numberOfRowsInSection 中的最后一部分开始

Question

这可能看起来与此重复:numberOfRowsInSection starts with last section ，但是提供的解决方案对我来说不起作用，很久以前就有人问过它，而且它是用 Objective-C 编写的。 AFAIK 语言与此无关。

步骤:

1. 调用API
2. 向数组添加响应 - 10 个结果
3. 重新加载表格
4. numberOfRowsInSections 被调用。

5. print("section:\(section)") in numberOfRowsInSections 打印

   section: 9
   section: 0
   section: 1
   section: 2
   section: 3
   section: 4
   section: 5
   section: 6
   section: 7
   section: 8
   

这是不受欢迎的行为，因为我希望每个部分中有不同的行数。

由于 numberOfRowsInSections 决定每个部分中的单元格数量，因此我根据每个数组中的某些值来计算部分的数量。

}

TableView 方法是:

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    let post = arrPost[section]
    let comment = post.last_comment

    print("section: \(section)")

    if post.upload_type! == "0" {
        if let _ = comment!.comment_id {
            return 2
        } else {
            return 1
        }
    } else {
        if let _ = comment!.comment_id {
            return 3
        } else {
            return 2
        }
    }

}

Answer 1

响应参数类型存在一些问题。

最终结论如 @Avt 在评论中所说:

If correctly implemented UITableViewDataSource/delegate it should work regardless which section is requested first.
