iOS12-crash错误-reason: 'UITableView failed to obtain a cell from its dataSource'

错误原因：

cellForRowAtIndexPath函数返回了nil

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {let cell = tableView.dequeueReusableCell(withIdentifier: "reuseIdentifier", for: indexPath)// Configure the cell...return cell}
复制代码

解决方法：

检查：

1.storyboard上有没有给cell加identifier

2.identifier有没有写错

3.函数本身是不是还没实现

4.if else返回其中一个cell时的判断错乱了

5.想到再加
