iOS swift-view不能勾选xib了

1.先创建一个集成自view的  UseBikeView_one.swift

2.再创建一个同名xib文件，UseBikeView_one.xib

3.把xib文件按如下操作

4.到UseBikeView_one.swift设置如下代码，即可正常使用xib

var XibView:UIView!

//初始化时将xib中的view添加进来

override init(frame: CGRect) {

super.init(frame: frame)

XibView = loadViewFromNib()

print("大小\(frame)")

XibView.frame = CGRect(x: 0, y: 0, width: frame.width, height: frame.height)

addSubview(XibView)

}

//初始化时将xib中的view添加进来

required init?(coder aDecoder: NSCoder) {

super.init(coder: aDecoder)

XibView = loadViewFromNib()

addSubview(XibView)

}

//加载xib

func loadViewFromNib() -> UIView {

let className = type(of: self)

let bundle = Bundle(for: className)

let name = NSStringFromClass(className).components(separatedBy: ".").last

let nib = UINib(nibName: name!, bundle: bundle)

let view = nib.instantiate(withOwner: self, options: nil).first as! UIView

return view

}
