將XIB中的視圖加載到ViewController和VIewCell中

Question

. 我有一個帶有自定義類的XIB。 and , both with . 我也有和 ，它們都具有 。

. 我想要的是將筆尖加載到 。 which I guess is not the best solution and i have to set frame manually. 到目前為止，我是通過加載NIB然后將其添加為的子視圖來 ，我認為這不是最佳解決方案，因此我必須手動設置框架。

let view = NSBundle.mainBundle().loadNibNamed("ProfileHeaderView", owner: self, options: nil).last as! ProfileHeaderView
view.setFrame(...)
self.profileHeaderView.addSubview(self.view)

最好的方法是什么？

Answer 1

首先，創建自定義視圖類

class CustomView: UIView {

    // MARK: Custom View Initilization
    var view: UIView!

    func xibSetup() {
        view = loadViewFromNib()
        view.frame = bounds
        view.autoresizingMask = UIViewAutoresizing.FlexibleWidth | UIViewAutoresizing.FlexibleHeight
        addSubview(view)
        //// additional setup here
    }
    func loadViewFromNib() -> UIView {
        let bundle = NSBundle(forClass: self.dynamicType)
        // set nibName to be xib file's name
        let nib = UINib(nibName: "CustomView", bundle: bundle)
        let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
        return view
    }
    override init(frame: CGRect) {
        super.init(frame: frame)
        xibSetup()
    }
    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
        xibSetup()
    }

}

其次，在CustomView.xib中將File's owner自定義類設置為CustomView

之后，您就完成了。 您可以通過編程方式創建自定義視圖。

let customView = CustomView(frame: frame)
self.view.addSubview(customView)

或使用情節CustomView ，通過將UIView拖到ViewController並將UIView的自定義類設置為CustomView
