ios - 当视图控制器中包含自定义视图时应用程序冻结

Question

当我将ProfileHeaderView作为子视图添加到 a时MDCFlexibleHeaderViewController，出现以下错误：

Thread 1: EXC_BAD_ACCESS (code=2, address=0x991fd4)

调用以下方法时会引发错误：

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    self.commonInit()
}

调用super.init()方法时会调用错误。我没有看到控制台中打印出更多错误消息。关于如何解决它的任何想法？

仅供参考，ProfileHeaderView该类的代码如下所示：

class ProfileHeaderView: UIView {

@IBOutlet var header: ProfileHeaderView!

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

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    self.commonInit()
}

private func commonInit(){
    Bundle.main.loadNibNamed("ProfileHeaderView", owner: self, options: nil)
    addSubview(header)
    header.frame = self.bounds
    header.autoresizingMask = [.flexibleHeight,.flexibleWidth]
}

/*
// Only override draw() if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func draw(_ rect: CGRect) {
    // Drawing code
}
*/

}

我不继承MDCFlexibleHeaderViewController.
