ios – 如何使用swift代碼在按鈕單擊中在自定義UITableViewCell中顯示UIAlertController？

此代碼在UITableViewCel中給出錯誤,如上圖所示.
請幫幫我.全班代碼如下：

class CustomCellDeerCalls: UITableViewCell {override func awakeFromNib() {    super.awakeFromNib()    // Initialization code}@IBOutlet weak var playButton: UIButton!@IBOutlet weak var detialsInfoButton: UIButton!@IBOutlet weak var DeerCallNameLabel: UILabel!var arrayOfDetialsInfoDeerCalls: [String]=["This sound is a doe's way of locating other deer of her family group . This call can be used all year long.","Grunts are a doe's way of saying come here,also to call her fawns at feeding time . It is critical to keep the call soft as a loud grunt is too aggressive of a call.","A buck grunt is a deeper pitch than a doe grunt,it means the same thing . The older the buck the deeper the tone. ","As the buck chases the doe as the rut approaches he is frustrated,and makes a series of soft grunts while trailing her. It's the bucks way of asking her to stop so he can be breed with her.","This sound's a lot like a calf bawl,but it is a series of buck bleats. This signals the bucks desire for company.","This is a non aggressive and social behaviour that all bucks do after shedding their velvet . This is when the bucks learn who can whip the other . This process does not prevent serious fights later on during the rut.","This is the sound that a buck makes during the courtship when the doe stops running,but won't let the buck breed her. It's a non aggressive and frustration call by him.","This is the sound that a Doe makes to signal that her breeding time is near.","This is the sound that a Doe makes to signal that she ready to breed RIGHT NOW.","Deer make this sound to intimidate other deer and prevent fights. This call is often made by a rut- crazed buck when confronted with a rival. This sound can send smaller buck running from the area.","Another rut crazed Bucks sound to intimidate other deer and prevent fights when confronted with a rival. This sound can also send smaller buck running from the area.","This is a short aggressive rattling sequence to possibly lure in less aggressive,but curious buck,as well as the local dominant whitetail buck of the area. To make this sound like a real fight sniffs,wheezes and grunts have also been thrown in for added effect."]var arrayOfDeerSoundsCall: [String]=["CONTACT","doegrunt","bkgrunt","tend","bawl","spar","rage","estrusb","bellow","sniff","wheeze","rattle"]

// var arrayOfCallsName：[String] = [“”]
