Swift：在调用函数时创建UI

I've got one of these Views here:

我在这里有一个观点:

let placeContainerView: UIView = {
    let view = UIView()
    view.backgroundColor = UIColor.whiteColor()
    view.translatesAutoresizingMaskIntoConstraints = false
    view.layer.cornerRadius = 7
    view.layer.masksToBounds = true

    return view
}()

And I'm looking to create one next to it every time a function "createNewView()" is called.

每次调用函数“createNewView()”时,我都希望在它旁边创建一个。

    let showFullPlaceContainerView = UITapGestureRecognizer(target: self, action: #selector(showFullPlaceContainerViewFunction))
    placeContainerView.addGestureRecognizer(showFullPlaceContainerView)

That I want each of the placeContainerView's to respond to.

我希望每个placeContainerView都能响应。

So I want a view to be generated and I'll give it certain values. And then when I call the function createNewView() I'll get a new view next to it that is exactly the same except with whatever new values I put in.

所以我希望生成一个视图,我会给它一些值。然后当我调用函数createNewView()时,我会在它旁边看到一个新视图,除了我输入的任何新值之外,它是完全相同的。

If you've got any ideas please let me know!

如果您有任何想法,请告诉我!

Thank you

EDIT:

The code below demonstrates how I want to setup the placeContainerView each time but I need them to be displayed so that the placeContainerView.topAnchor() is different each time.. How exactly does that work if it is kept in its own class and doesn't know how many times it has been created?

下面的代码演示了我每次都想设置placeContainerView的方法,但是我需要显示它们,以便每次placeContainerView.topAnchor()都不同。如果将它保存在自己的类中并且没有它,那该怎么办?知道创建了多少次?

Also, as placeContainerView contains placeLabel and placeImageView do these have to be generated inside the new PlaceContainerViewClass as well?

另外,由于placeContainerView包含placeLabel和placeImageView,这些必须在新的PlaceContainerViewClass中生成吗?

func setupPlaceContainerView() {
    placeContainerView.leftAnchor.constraintEqualToAnchor(view.leftAnchor, constant: -180).active = true
    placeContainerView.topAnchor.constraintEqualToAnchor(view.topAnchor, constant: 80).active = true
    placeContainerView.widthAnchor.constraintEqualToConstant(227).active = true
    placeContainerView.heightAnchor.constraintEqualToConstant(45).active = true


    placeContainerView.addSubview(placeLabel)
    placeContainerView.addSubview(placeImageLabelSeparator)
    placeContainerView.addSubview(placeImageView)

    placeLabel.leftAnchor.constraintEqualToAnchor(placeContainerView.leftAnchor).active = true
    placeLabel.topAnchor.constraintEqualToAnchor(placeContainerView.topAnchor).active = true
    placeLabel.widthAnchor.constraintEqualToConstant(180).active = true
    placeLabel.heightAnchor.constraintEqualToAnchor(placeContainerView.heightAnchor).active = true

    placeImageLabelSeparator.leftAnchor.constraintEqualToAnchor(placeLabel.rightAnchor).active = true
    placeImageLabelSeparator.topAnchor.constraintEqualToAnchor(placeContainerView.topAnchor).active = true
    placeImageLabelSeparator.widthAnchor.constraintEqualToConstant(2).active = true
    placeImageLabelSeparator.heightAnchor.constraintEqualToAnchor(placeContainerView.heightAnchor).active = true

    placeImageView.leftAnchor.constraintEqualToAnchor(placeImageLabelSeparator.rightAnchor).active = true
    placeImageView.topAnchor.constraintEqualToAnchor(placeContainerView.topAnchor).active = true
    placeImageView.widthAnchor.constraintEqualToConstant(45).active = true
    placeImageView.heightAnchor.constraintEqualToAnchor(placeContainerView.heightAnchor).active = true

As noted by @Paulw11, this task is simply done by creating a new class.

正如@Pahnw11所指出的,这项任务只需创建一个新类即可完成。

class placeContainerView:UIView {

    var x:Double!
    var y:Bool!
    var z:UILabel!
    var controller:UIViewController!

    //If you want to pass specific values number, you can use convenience init method OR you can use the default init method they give you.
    //previousLabelFrame:CGrect = CGRect() // I defaulted all these values to 0, make them whatevree u need. You would use the default one for the first Label you would make. Then after that, you would pass in the previous one made, to get the frame of it so you can add to the one after that. 
    convenience init(x:Double,y:Bool, z:UILabel, previousLabelFrame:CGRect = CGRect(x: 0, y:0, width:0, height:0), VC:UIViewController) {
        self.x = x
        self.y = y
        self.z = z
        self.controller = VC
        let distance = self.controller.width*0.1 //Whatever u decide here
        //You could just do CGRect(x:previousLabelFrame.maxX+distance, depeding on what you need. 
        self.frame = CGRect(x: previousLabelFrame.minX+distance, y:previousLabelFrame.minY, width: previousLabelFrame.width, height:previousLabelFrame.height)
    }

}

Usage inside ViewController:

ViewController中的用法:

var views:[placeContainerView] = []

let view:placeContainerView = placeContainerView(10, true, UILabel(),views[views.count-1], self)
 self.views.append(view)
//OR if this is the FIRST placeContainerView of the whole app, it will use the default values for the frame.
let view:placeContainerView = placeContainerView(10, true, UILabel(), self)
self.views.append(view)

Some odd example of how to use. Then everytime they click a button, just make a new placeContainerView

一些奇怪的例子如何使用。然后每次他们点击一个按钮,只需创建一个新的placeContainerView
