UITableViewAutomaticDimension直到滚动才工作 [英] UITableViewAutomaticDimension not working until scroll

问题描述

首次加载表视图时，所有可见单元格都是estimatedRowHeight。当我向下滚动时，单元格会自动调整大小，当我向上滚动时，最初估计的单元格会自动调整大小。

When the Table View is first loaded, all of the visible cells are the estimatedRowHeight. As I scroll down, the cells are being automatically sized properly, and when I scroll back up the cells that were initially estimatedRowHeight are being automatically sized properly.

一旦单元格为由于自动调整大小，它们似乎不会再回到估计的行高。

Once the cells are being automatically sized, they don't ever seem to go back to being the estimatedRowHeight.

override func viewDidLoad() {
    super.viewDidLoad()
    self.navigationItem.backBarButtonItem = UIBarButtonItem(title: "", style: .Plain, target: nil, action: nil)
    self.tableView.estimatedRowHeight = 80.0
    self.tableView.rowHeight = UITableViewAutomaticDimension

    // Uncomment the following line to preserve selection between presentations
    // self.clearsSelectionOnViewWillAppear = false

    // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
    // self.navigationItem.rightBarButtonItem = self.editButtonItem()
}

和

    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {

    let cellIdentifier = "Cell"
    let cell = tableView.dequeueReusableCellWithIdentifier(cellIdentifier, forIndexPath: indexPath) as CustomTableViewCell

    // Configure the cell...
    let restaurant = restaurants[indexPath.row]
    cell.namelabel.text = restaurant.name
    cell.locationlabel.text = restaurant.location
    cell.typelabel.text = restaurant.type
    cell.thumbnailImageView.image = UIImage(named: restaurant.image)
    cell.thumbnailImageView.layer.cornerRadius = cell.thumbnailImageView.frame.size.width / 2
    cell.thumbnailImageView.clipsToBounds = true
    cell.accessoryType = restaurant.isVisited ? .Checkmark : .None

    return cell
}

思考关于如何让细胞最初自动调整？

Thoughts on how to have the cells autoresize initially?

更新：从Xcode 7 beta 6开始，这不再是一个问题

UPDATE: As of Xcode 7 beta 6 this is no longer an issue

推荐答案

我遇到了同样的问题，发现附件 cell.accessoryType 当它不是无时会自动调整大小，所以它似乎是Xcode中的一个错误。

I ran into the same issue and found out that the accessory cell.accessoryType messes with this automatic resizing when it is not None, so it seems like a bug in Xcode at the moment.

但正如@Blankarsch所说，调用 reloadSections（..）有助于解决此问题，如果你需要附件。

But as @Blankarsch mentioned, calling reloadSections(..) helps to fix this issue if you need to have an accessory.
