swift - Xcode:运算符后的预期表达式

Question

    {
        self.myCBControler = CoreBluetoothController()
        self.sozNum = globSozNumber
        self.insert = false
        self.stateStopBLE = true

        print("Initialized Blood Pressure View!!")
        super.init(coder: aDecoder ?? default value)
    }

我在最后一行遇到了“默认值”和“super.init”错误(我认为是这样)错误是:“运算符后的预期表达式”和“必须调用父类(super class)“UIViewController”的指定初始值设定项”非常乐意帮助我们，谢谢

Answer 1

只需将构造函数中获得的参数传递给 super 构造函数即可:

override required init?(coder aDecoder: NSCoder)
{
    self.myCBControler = CoreBluetoothController()
    self.sozNum = globSozNumber
    self.insert = false
    self.stateStopBLE = true

    print("Initialized Blood Pressure View!!")
    super.init(coder: aDecoder)
}    

您可能需要调整自定义初始化和 super 初始化程序的顺序(这取决于属性的类型):

override required init?(coder aDecoder: NSCoder)
{
    super.init(coder: aDecoder)

    self.myCBControler = CoreBluetoothController()
    self.sozNum = globSozNumber
    self.insert = false
    self.stateStopBLE = true

    print("Initialized Blood Pressure View!!")
}
