xib写 tableHeadView , frame 不准确的解决方法

打印 headView 的信息后可以看到 autoresize 的属性为 W+H,这个属性决定了 headView会根据 tableview 动态调整宽高

所以我们只要将这个动态调整禁用掉就可以解决这个问题了

禁用方法: 设置autoresizingMask的属性为默认值 0, OC 为UIViewAutoresizingNone

private lazy var headView: AFMineTableHeadView = {
        let nib = UINib(nibName: "AFMineTableHeadView", bundle: nil)
        let headV = nib.instantiate(withOwner: self, options: nil)[0] as! AFMineTableHeadView
        headV.delegate = self
        headV.autoresizingMask = UIViewAutoresizing(rawValue: 0)
        return headV
    }()
