获取输出帧失败，状态8196 [英] get output frames failed, state 8196

问题描述

当我尝试自定义tableView单元格时，发现此错误.

When I try to customise a tableView cell, I found this error.

获取输出帧失败，状态8196"

"Get output frames failed, state 8196"

我只是不知道这是领域还是我的自定义tableView单元中的错误.

I just have no idea it is the error from realm or from my customise tableView cell.

class StudentTableViewController: UITableViewController {

    let realm = try! Realm()
    var student: Results<StudentName>?
    var selectedClass: ClassName? {
        didSet {
            load()
        }
    }
    var selected: String = ""

    override func viewDidLoad() {
        super.viewDidLoad()
        navigationController?.title = selected
        tableView.register(StudentTableViewCell.self, forCellReuseIdentifier: "studentName")
    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return student?.count ?? 1
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "studentName", for: indexPath) as! StudentTableViewCell
        cell.name.text = student?[indexPath.row].name ?? "There are no student in this class"
        cell.number.text = "\(student?[indexPath.row].studentNumber ?? 0)"
        return cell
    }
    func load() {
        student = selectedClass?.studentNames.sorted(byKeyPath: "studentNumber", ascending: true)
        tableView.reloadData()
    }
}

我认为当我使用Xcode 9和Swift 4.1时它确实起作用了，但是现在在Xcode 10中却没有，因为它只向我显示此错误和表格视图的整个空白页.

I think it did work when I am using Xcode 9 and Swift 4.1 but now in Xcode 10 it doesn't since it only show me this error and whole blank page of table view.

推荐答案

如果该单元格具有单独的.xib文件，则应使用:

If you have a separate .xib file for the cell, you should use:

tableView.register(nib: UINib?, forCellReuseIdentifier: String)

换句话说，您的单元格的注册将是这样的:

In other words the registration of your cell would be something like that:

self.tableView.register(UINib(nibName: "your cell nib name", bundle: nil), forCellReuseIdentifier: "your cell identifier")

如果您已将单元格放置在情节提要中位于控制器内的表格视图中，则无需注册您的单元格，如@DávidPásztor所述，请确保将单元格标识符添加到情节提要中的单元格

If you have placed your cell in the tableview inside the controller that sits in the Storyboard then you do not need to register your cell, and as @Dávid Pásztor mentioned make sure you add the cell identifier to the cell in the Storyboard
