如何在Swift中使用XIB文件初始化/实例化自定义UIView类 [英] How to initialize/instantiate a custom UIView class with a XIB file in Swift

问题描述

我有一个名为 MyClass 的类，它是 UIView 的子类，我想用<初始化 XIB 文件。我不知道如何使用名为 View.xib的xib文件初始化此类

I have a class called MyClass which is a subclass of UIView, that I want to initialize with a XIB file. I am not sure how to initialize this class with the xib file called View.xib

class MyClass: UIView {

    // what should I do here? 
    //init(coder aDecoder: NSCoder) {} ?? 
}

推荐答案

我测试了这段代码吧效果很好

I tested this code and it works great

class MyClass: UIView {

    class func instanceFromNib() -> UIView {
        return UINib(nibName: "nib file name", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as UIView
    }

}

初始化视图并使用如下所示

Initialise the view and use it like below

    var view = MyClass.instanceFromNib()
    self.view.addSubview(view)

OR

    var view = MyClass.instanceFromNib
    self.view.addSubview(view())

UDATE Swift> = 3.x

class func instanceFromNib() -> UIView {
    return UINib(nibName: "nib file name", bundle: nil).instantiate(withOwner: nil, options: nil)[0] as! UIView
}
