iphone - 如何将 Storyboard中创建的 UIView 添加为 Swift 中的弹出窗口？

Question

我做了以下事情:1.拖拽UIView放置在ViewController功能区

1. 创建了一个自定义 UIView 类并将导出添加到“编辑配置文件 View ” View 字段:

导入 UIKit

类 EditProfileView:UIView {

let globalDataHandler = GlobalDataHandler.sharedInstance

@IBOutlet weak var firstNameTextField: UITextField!
@IBOutlet weak var lastNameTextField: UITextField!
@IBOutlet weak var userNameTextField: UITextField!
@IBOutlet weak var passwordTextField: UITextField!
@IBOutlet weak var emailTextField: UITextField!
@IBAction func saveEditButton(sender: AnyObject) {
}
@IBAction func cancelEditButton(sender: AnyObject) {
}

/*
// Only override drawRect: if you perform custom drawing.
// An empty implementation adversely affects performance during animation.
override func drawRect(rect: CGRect) {
    // Drawing code
}
*/

1. 将“EditProfileView”类作为Storyboard 中“Edit Profile View” View 的自定义类。

2. 在 ProfileViewController 中为“EditProfileView”类创建了一个对象，并将“Edit Profile View” View 添加到主视图点击 ProfileViewController 中的编辑按钮。

类 ProfileViewController: UIViewController {

let profileView = EditProfileView()

override func viewDidLoad() {
    super.viewDidLoad()
}

@IBAction func editProfileButton(sender: AnyObject) {
    profileView.firstNameTextField.text = "First Name"
    profileView.lastNameTextField.text = "Last Name"
    profileView.userNameTextField.text = "User Name"
    profileView.emailTextField.text = "Email"
    let testFrame : CGRect = CGRectMake(50,100,300,300)
    profileView.frame = testFrame
    self.view.addSubview(profileView)
}

但是，“编辑配置文件 View ” View 不会出现在 ProfileViewController 上。请帮忙。

Answer 1

您必须在 Xib 中链接您的 UIView 和您的 View (应该是一个不同的 UIViewController)。

profileView = storyboard.instantiateViewControllerWithIdentifier("ProfileViewController")

您的 ProfileVC 必须有一个 UIPresentationController

class ProfilePresentationController : UIPresentationController {
    override func frameOfPresentedViewInContainerView() -> CGRect {
        return CGRect(x: (presentingViewController.view.frame.width / 2.0) - 150.0, y: (presentingViewController.view.frame.height / 2.0) - 100.0, width: 300.0, height: 200.0)
    }
}

您的 EditProfileView 必须实现以下委托(delegate):

UIViewControllerTransitioningDelegate

您的 profileView 的以下属性也必须设置为:

profileView.modalPresentationStyle = UIModalPresentationStyle.Custom
profileView.transitioningDelegate = self

之后你可以实现委托(delegate)所需的方法

func presentationControllerForPresentedViewController(presented: UIViewController, presentingViewController presenting: UIViewController, sourceViewController source: UIViewController) -> UIPresentationController? {
        return ProfilePresentationController(presentedViewController: presented, presentingViewController: presenting)
}
