how to create a pop up view in Swift
提问by sky1995
So I am trying to create a pop up view within an existing view: Whenever a button is pushed, the pop up view comes up
所以我试图在现有视图中创建一个弹出视图：每当按下按钮时，弹出视图就会出现
this is the code I've used to when the button is pressed
这是我按下按钮时使用的代码
@IBAction func addFees(sender: UIButton) {
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(0.3)
view2.frame = CGRectMake(0, 200, 320, 261)
UIView.commitAnimations()
}
this is the code I use to make it go away
这是我用来让它消失的代码
@IBAction func doneButton(sender: UIBarButtonItem) {
UIView.beginAnimations(nil, context: nil)
UIView.setAnimationDuration(0.3)
listingfees.frame = CGRectMake(0, 1000, 320, 261)
UIView.commitAnimations()
}
The problem is that I have other buttons and labels and they seem to overlap when the view comes up. I don't know how to fix it. I am not sure if there is an easier away but I've been stuck on this problem for a while.
问题是我有其他按钮和标签，当视图出现时它们似乎重叠。我不知道如何修复它。我不确定是否有更简单的方法，但我已经被这个问题困住了一段时间。
I want it to look something like the picture on the right
我希望它看起来像右边的图片

Popover should be presented from base view controller if you want it to be on top
如果您希望它位于顶部，则应从基础视图控制器呈现弹出框
@IBAction func addFees(sender: UIButton){
let viewController = "Your Popover View Controller class"
viewController.modalPresentationStyle = .Popover
viewController.preferredContentSize = CGSizeMake(320, 261)
let popoverPresentationViewController = viewController.popoverPresentationController
popoverPresentationViewController?.permittedArrowDirections = .Any
popoverPresentationViewController?.delegate = self
popoverPresentationController?.sourceRect = sender.frame
presentViewController(playerInformationViewController, animated: true, completion: nil)
}
}
