我需要创建一个新的popover视图,因为锚在编译期间在Interface Builder中不可见.
根据this post,执行委托方法将迫使iPhone上的Popover. (原因我不明白)
当在帖子中显示的时候,它的效果很好.但是我不能让这个工作在非隔断的方式. (Popover确实显示在iPad上)
请帮忙！
代码如下：
func showOptions() {
let contentView = UIStoryboard(name: "Main",bundle: nil).instantiateViewControllerWithIdentifier("PasteOption") as NewPasteOptionViewController
contentView.modalPresentationStyle = UIModalPresentationStyle.Popover
contentView.preferredContentSize = CGSizeMake(200.0,200.0)
presentViewController(contentView,animated: true,completion: nil)
var _popoverPresentationController = contentView.popoverPresentationController!
_popoverPresentationController.delegate = self
_popoverPresentationController.permittedArrowDirections = UIPopoverArrowDirection.Any
_popoverPresentationController.sourceView = view
_popoverPresentationController.sourceRect = self.navigationItem.titleView!.frame
}
// this function below is never called.
func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
return UIModalPresentationStyle.None
}
补充笔记：
呈现视图控制器在另一视图中呈现为模态表单,并封装在导航控制器中.
呈现的视图控制器是自定义表视图控制器.
