将XIB中的视图加载到ViewController和VIewCell中

[英]Loading view from XIB into ViewController and VIewCell

. 我有一个带有自定义类的XIB。 and , both with . 我也有 ,它们都具有

. 我想要的是将笔尖加载到 which I guess is not the best solution and i have to set frame manually. 到目前为止,我是通过加载NIB然后将其添加为的子视图来 ,我认为这不是最佳解决方案,因此我必须手动设置框架。

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?

首先,创建自定义视图类

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中将File's owner自定义类设置为CustomView


之后,您就完成了。 您可以通过编程方式创建自定义视图。

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

或使用情节CustomView ,通过将UIView拖到ViewController并将UIView的自定义类设置为CustomView
