我在桌面视图单元格中有三个按钮，当点击按钮时，它会被奇怪地排在行中我附上代码和崩溃报告请提出解决方案。
按钮点击代码：
@IBAction func ibaReject(sender: UIButton) {
let notification = notifications[sender.tag]
let notificationHandler = NotificationHandlerFactory.getNotificationHandler(notification)
notificationHandler?.handleNegativeAction(notification,viewController: self)
}
崩溃的崩溃报告：
