在dequeueReusableCell之后的单元格布局

Question

Can I assume that after getting a cell from let cell = tableView.dequeueReusableCell() the cell will have all it's contents sizes (specifically - will be laid out) and I can safely access fe the width of a label that's residing inside the cell?

It seems to be working in my project, but I wanted to be totally shure, but cannot find relevant information in docs.

Answer 1

如果要获取单元格中存在的标签宽度，则可以使用tag属性获取标签及其宽度。

Answer 2

Much more reliable:

override func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
    // do your setup tasks here
}
