OC调用Swift的set方法,调用Bool的set方法报错 Property cannot be marked @objc because its type cannot be represented in Objective-C

swift中的写法

    //set传值
    @objc var titleString:String? {
        willSet{
        }
        didSet{
           //处理逻辑
        }
    }
    //set
    @objc var collectState:Bool = false {  //此处一定要给初始值
        willSet{
        }
        didSet{
            //处理逻辑
        }
    }

如果不给定初始值的话会报错，
Property cannot be marked @objc because its type cannot be represented in Objective-C

oc中调用

    self.XXX.titleString = @"测试数据";
    self.XXX.collectState = true;

记录下来用于提醒自己，如有错误望指正。
