STPopup 如何在 Swift 中初始化？

Question

Im playing with this library . It says that I have to init it with code

STPopupController *popupController = [[STPopupController alloc] initWithRootViewController:[ViewController new]];
[popupController presentInViewController:self];

I try to do this with following code (HelpersNear is name of UIViewController)

var popup = STPopupController(rootViewController: HelpersNear)
popup.presentInViewController(self)

but in response I get compile error which offers me to delete rootViewController from constructor. After I remove it, I get another error.

What am I doing wrong ?

Answer 1

Try this code:

var popup = STPopupController(rootViewController: HelpersNear())
popup.presentInViewController(self)

For example:

class FooViewController: UIViewController {  
  let name: String

  init() {
    name = "Bar"
    super.init(nibName: nil, bundle:nil)
  }

  required init(coder: NSCoder) {
    super.init(coder: coder)
  }
}

There is easy way to use this library in Swift. Below I put example for BottomSheet style popup using STPopupController.

1. Create UIViewController or UITableViewController in Storyboard (you can use example done in Example Project (STPopupExample) of STPopup library available on github).

2. Set the view controller's storyboard id to f.ex.: MultiselectionTableViewController

3. To show this popup view use the following code:

    let storyboard = UIStoryboard(name: "Main", bundle: nil) let vc = storyboard.instantiateViewControllerWithIdentifier("MultiselectionTableViewController") as! MultiselectionTableViewController vc.title = "Choose your options" vc.items = ["First element", "Second element", "Third element"] vc.delegate = self let popup = STPopupController(rootViewController: vc) popup.style = STPopupStyle.BottomSheet dispatch_async(dispatch_get_main_queue(), { popup.presentInViewController(self.parentViewController) })

4. It is important to show popup inside dispatch_async block. It prevents lags in showing new view controller.
