I have just a quick question:
Is there a way to impersonate a View? I have designed a View in Storyboard. But now I want to use many Views which are exactly the same as the one designed in Storyboard. I basically just want to "copy" the view 7 times. I`ve tried
let testarray:[UIView] = [someview, someview, someview]
But then of course if I change the values of one view it changes the value of all views and thats not what I wont. I hope you understand what I want to do because my english skills are not that brilliant.

是的，可以使用Xibs。我个人这样做的方式是以下
(defvar ar-move-line-this-column nil)
(defun ar-move-line-keep-column-intern (arg)
(unless (eq last-command this-command)
(setq ar-move-line-this-column (current-column)))
(forward-line arg)
(while (and (not (eolp)) (< (current-column) ar-move-line-this-column))
(forward-char 1)))
(defun ar-forward-line-keep-column (&optional arg)
"Go to current column of next line.
If line is shorter, go to end of line"
(interactive "p")
(ar-move-line-keep-column-intern (or arg 1)))
(defun ar-backward-line-keep-column (&optional arg)
"Go to current column of line above.
If line is shorter, go to end of line"
(interactive "p")
(ar-move-line-keep-column-intern (- arg)))
文件，里面有一个视图，让我们说.xib MyView.xib内创建一个.swift文件。在此内部放置所有MyView.swift和所有内容。@IBOutlet内，添加MyView.xib作为xib的所有者，并将出口链接到子视图确保您的课程MyView扩展了您可以添加到项目中的以下课程MyView（这是我在项目中使用的课程）
CustomXibView@IBDesignable
class CustomXibView: UIView {
@objc internal var defaultXib: String {
return String(describing: type(of: self))
}
override init(frame: CGRect) {
super.init(frame: frame)
loadXib(xib: defaultXib)
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
loadXib(xib: defaultXib)
}
private func loadXib(xib: String) {
// Load view
let bundle = Bundle(for: type(of: self))
let nib = UINib(nibName: xib, bundle: bundle)
let contentView = nib.instantiate(withOwner: self, options: nil)[0] as! UIView
// use bounds not frame or it'll be offset
contentView.frame = bounds
// Make the view stretch with containing view
contentView.autoresizingMask = [UIViewAutoresizing.flexibleWidth, UIViewAutoresizing.flexibleHeight]
// Make sure layout uses superview margins
preservesSuperviewLayoutMargins = true
// Adding custom subview on top of our view
addSubview(contentView)
}
}
