Question

是否可以在不重新加载单元格的情况下为自定义UITableViewCell中的UILabel设置值？

我尝试了许多排列：

let indexPath = NSIndexPath(forRow: 0, inSection: 0)
let cell = tableView.cellForRowAtIndexPath(indexPath) as! CustomTableViewCell1
cell.customLabel.text = "text goes here"

..我不明白为什么这不起作用。我在UITableViewCell中有一个UITextField，当我设置textField值时，我只想更新标签，但不重新加载整个单元格。有什么建议吗？

Answer 1

如果要更新UIViews，则需要将它们放在主线程中：

dispatch_async(dispatch_get_main_queue(),{
   cell.customLabel.text = "text goes here"
})
