Question

在构建我的应用时，我遇到了这个错误：

线程1：信号SIGABRT

在日志中，出现此消息

libc++abi.dylib: terminating with uncaught exception of type NSException

这是我在ViewController数据源中使用的代码

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

    let cell = tableView.dequeueReusableCellWithIdentifier("cell", forIndexPath: indexPath)

    Compiti.text = self.messagesArray[indexPath.row]
    FotoCompiti.image = self.imagesArray[indexPath.row]
    DataCompiti.text = self.dateArray[indexPath.row]

    return cell
}

我还加倍检查可重用的小区标识符是否相同。

Answer 1

在cellforrowAtIndexPath

中更改此类逻辑

    var cell = UITableViewCell?
    cell=tableView.dequeueReusableCellWithIdentifier("ReUseCell")
    if cell==nil
    {
        cell = UITableViewCell(style: UITableViewCellStyle.Value1, reuseIdentifier: "ReUseCell")

    }
    Compiti.text = self.messagesArray[indexPath.row]
    FotoCompiti.image = self.imagesArray[indexPath.row]
    DataCompiti.text = self.dateArray[indexPath.row]

    return cell
