How to create a custom pop up view with swift?
提问by J Arango
So I am working on a simple app, where I use a table view. This table view displays the name of "players". But in order for me to add players in the table view, I want a pop up window to be displayed with a text field where you provide the name.
所以我正在开发一个简单的应用程序，我在其中使用表视图。此表视图显示“玩家”的名称。但是为了让我在表格视图中添加玩家，我想要一个弹出窗口显示一个文本字段，您可以在其中提供名称。
Now I have been reading about creating a xib or nib file, but I am not sure how to "load" the pop up window.
现在我一直在阅读有关创建 xib 或 nib 文件的信息，但我不确定如何“加载”弹出窗口。
What's the best approach to this?
最好的方法是什么？

In storyboard
在故事板中
- In storyboard create one UIViewController and design it according to your requirement.
- Set custom class as anotherViewController and Storyboard_ID as another_view_sid
- Create one new Cocoa Touch Class as anotherViewController and subclass of UIVIewController
- 在故事板中创建一个 UIViewController 并根据您的要求进行设计。
- 将自定义类设置为 anotherViewController 并将 Storyboard_ID 设置为 another_view_sid
- 创建一个新的 Cocoa Touch 类作为 anotherViewController 和 UIVIewController 的子类
In viewController
在视图控制器中
let popvc = UIStoryboard(name: "Main", bundle: nil).instantiateViewController(withIdentifier: "another_view_sid") as! anotherViewController
self.addChildViewController(popvc)
popvc.view.frame = self.view.frame
self.view.addSubview(popvc.view)
popvc.didMove(toParentViewController: self)
In anotherViewController
在另一个视图控制器中
override func viewDidLoad() {
super.viewDidLoad()
showAnimate()
}
}
@IBAction func Close_popupView(_ sender: Any) {
removeAnimate()
}
func showAnimate()
{
self.view.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
self.view.alpha = 0.0
UIView.animate(withDuration: 0.25, animations: {
self.view.alpha = 1.0
self.view.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
})
}
func removeAnimate()
{
UIView.animate(withDuration: 0.25, animations: {
self.view.transform = CGAffineTransform(scaleX: 1.3, y: 1.3)
self.view.alpha = 0.0
}, completion: {(finished : Bool) in
if(finished)
{
self.willMove(toParentViewController: nil)
self.view.removeFromSuperview()
self.removeFromParentViewController()
}
})
}

you'd create an custom UIViewwith all respected object needed, from your Controller's viewDidLoad() you'll hide it.
您将UIView使用所需的所有受尊敬的对象创建一个自定义，从您的控制器的 viewDidLoad() 中您将隐藏它。
customView.hidden = true
Whenever your user wants to perform some action or task, you unhide it and once the user finished then hide it againor remove from the superView.
每当您的用户想要执行某些操作或任务时，您都可以取消隐藏它，一旦用户完成，然后再次隐藏它或从 superView 中删除。
customView.hidden = false
Below there is some code to help you start
下面有一些代码可以帮助您开始
private var customView: UIView!
override func viewDidLoad() {
super.viewDidLoad()
customView.hidden = true
}
private func loadCustomViewIntoController() {
let customViewFrame = CGRect(x: 0, y: 0, witdh: view.frame.width, height: view.frame.height - 200)
customView = UIView(frame: customViewFrame)
view.addSubview(customView)
customView.hidden = false
// any other objects should be tied to this view as superView
// for example adding this okayButton
let okayButtonFrame = CGRect(x: 40, y: 100, width: 50, height: 50)
let okayButton = UIButton(frame: okayButtonFrame )
// here we are adding the button its superView
customView.addSubview(okayButton)
okayButton.addTarget(self, action: #selector(self.didPressButtonFromCustomView:), forControlEvents:.TouchUpInside)
}
func didPressButtonFromCustomView(sender:UIButton) {
// do whatever you want
// make view disappears again, or remove from its superview
}
@IBAction func rateButton(sender:UIBarButtonItem) {
// this barButton is located at the top of your tableview navigation bar
// when it pressed make sure you remove any other activities that were on the screen, for example dismiss a keyboard
loadCustomViewIntoController()
}
Check it out this github project, It's closed to be production ready, it gives you a better way to deal (present and dismiss) with UIViews
看看这个github 项目，它已关闭生产准备，它为您提供了一种更好的方式来处理（呈现和关闭）UIViews
If you only want the player's name then use a
UIAlertControllercontaining a textfield
如果您只想要播放器的名称，请使用
UIAlertController包含文本字段的
