STPopup 为 iPhone 和 iPad提供了 STPopupController UINavigationController 弹出的风格。
- Extend your view controller from UIViewController, build it in your familiar way.
- Push/Pop view controller in to/out of popup view stack, and set navigation items by using self.navigationItem.leftBarButtonItem and rightBarButtonItem, just like you are using UINavigationController.
- Support both "Form Sheet" and "Bottom Sheet" style.
- Work well with storyboard(including segue).
- Customize UI by using UIAppearance.
- Auto-reposition of popup view when keyboard is showing up, make sure your UITextField/UITextView won't be covered by the keyboard.
- Drag navigation bar to dismiss popup view.
- Support both portrait and landscape orientation, and both iPhone and iPad.
