Swift报错:fatal error: use of unimplemented initializer 'init(frame:)' for class

OC与Swift混编时，创建一个swift类继承自OC类，由于这个OC类已自定义构造函数，所以在这个swift类中重写父类的init构造函数初始化子控件，但是在运行时报错:
fatal error: use of unimplemented initializer 'init(frame:)' for class 'Arrietty.XYCustomAnnotationView'

解决方法:在这个swift类中重新 init(frame: CGRect)，并实现super方法即可

// MARK: - Life Cycle
    override init!(annotation: MAAnnotation!, reuseIdentifier: String!) {
        super.init(annotation: annotation, reuseIdentifier: reuseIdentifier)
        self.bounds = CGRect(x: 0.0, y: 0.0, width: kWidth, height: kHeight)
        self.backgroundColor = UIColor.clear
        
    
        self.addSubview(backgroundImageView)
        self.backgroundImageView.frame = CGRect(x: kHoriMargin, y: kVertMargin, width: kPortraitWidth, height: kPortraitWidth)
        /* 创建iconView展示用户头像 */
        self.backgroundImageView.addSubview(iconView)
        iconView.frame = CGRect(x: kHoriMargin, y: kVertMargin, width: kPortraitWidth, height: kPortraitWidth)
    }
    
    required init?(coder aDecoder: NSCoder) {
        fatalError("init(coder:) has not been implemented")
    }
    

    override init(frame: CGRect) {
        super.init(frame: frame)
    }
