我在Firebase上遇到了崩溃<compiler-generated> line 0 specialized MessagesCell.init(coder:)，仅在iOS 9.2.x或9上才收到此崩溃，我试图对其进行跟踪并了解到底发生了什么，但是在模拟器上却没有发生
这是我为tableView注册单元格的方式：
self.messagesTable.register(MessagesCell.self, forCellReuseIdentifier: "MessagesCell")
self.messagesTable.register(UINib(nibName: "MessagesCell", bundle: nil), forCellReuseIdentifier: "MessagesCell")
这是我的细胞班：
import UIKit
class MessagesCell: UITableViewCell {
@IBOutlet var myContentView: UIView!
override func awakeFromNib() {
super.awakeFromNib()
// Initialization code
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(selected, animated: animated)
// Configure the view for the selected state
}
}
这是崩溃日志，我们将不胜感激：

您只需要通过两种方式之一来注册单元格。因此，您可以保留第二个选项
self.messagesTable.register(UINib(nibName: "MessagesCell", bundle: nil), forCellReuseIdentifier: "MessagesCell")
注释第一行，它将开始工作。
//self.messagesTable.register(MessagesCell.self, forCellReuseIdentifier: "MessagesCell")
要向self.messagesTable.register(MessagesCell.self, forCellReuseIdentifier: "MessagesCell")注册，您还需要添加init(coder:)
