UIPopover without any arrows

问题

Is it possible to present a popover without any sort of arrows pointing somewhere?

回答1:

Yes it is possible just do:

 [self.popoverController presentPopoverFromBarButtonItem:anItem   
                                permittedArrowDirections:0
                                                animated:YES];

The zero represent no direction.

For iPhone and swift 2.0 try this one

Code to initiate popover

initiatePopover(){
    let popoverContent = self.storyboard?.instantiateViewControllerWithIdentifier("XYZController") as! XYZController
    let nav = UINavigationController(rootViewController: popoverContent)
    nav.modalPresentationStyle = UIModalPresentationStyle.Popover
    let popover = nav.popoverPresentationController
    popoverContent.preferredContentSize = CGSizeMake(250 ,200)
    popover!.delegate = self
    popover!.sourceView = self.view
    popover!.sourceRect = CGRectMake(200,200,0,0)
    popover!.permittedArrowDirections = UIPopoverArrowDirection(rawValue: 0)
    self.presentViewController(nav, animated: true, completion: nil)
}

And add this to your ViewController

func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {
    return UIModalPresentationStyle.None
}

回答3:

Set the permittedArrowDirections to 0.

permittedArrowDirections:0

Code -

[self.popoverController presentPopoverFromBarButtonItem:anItem   
                                permittedArrowDirections:0
                                                animated:YES];

Zero tells "NoDirection".

回答4:

Swift3, this code work for me

popover.permittedArrowDirections = .init(rawValue: 0)

回答5:

For Swift 2.0 and iOS9 the solution is:

popoverViewController?.permittedArrowDirections = UIPopoverArrowDirection()

回答6:

Swift4:

popover.permittedArrowDirections = []

回答7:

Try this , it works for me.

[self.popoverViewController presentPopoverFromRect:rect inView:self.view  permittedArrowDirections:0 animated:YES];

回答8:

This works fine for me.

[popoverController presentPopoverFromRect:CGRectMake(0, 0, 20, 20)
                                    inView:self.view 
                  permittedArrowDirections:NULL 
                                  animated:YES];

Enjoy Coding.

In Swift, you can simply do:

popoverPresentationController.permittedArrowDirections = []

Since in another configuration you could have used:

popoverPresentationController.permittedArrowDirections = [.up, .down]

回答10:

Nope, there is no UIPopoverArrowDirectionNone option, and UIPopoverArrowDirectionUnknown throws an exception i think if you try to use that to present.

Instead of a popover controller, you can call presentModalViewController:animated: and set the controller you are presenting to have a modal presentation style of UIModalPresentationFormSheet or perhaps UIModalPresentationPageSheet. Those are more traditional popup screens than popovers are.

回答11:

Do not use Popovers if you don't want to show arrows. Present your view controller as a Modal and use a UIModalPresentationFormSheet instead.

Example:

UIStoryboard *sb = [UIStoryboard storyboardWithName:@"MyStoryBoard" bundle:nil];
UIViewController* viewController = [sb instantiateViewControllerWithIdentifier:@"myViewController"];
viewController.modalPresentationStyle = UIModalPresentationFormSheet;
[presenterViewController presentViewController: viewController animated:YES completion:^{

}];

回答12:

In my case for swift developers

popoverController.sourceView = self.view
popoverController.sourceRect = self.view.bounds
popoverController.backgroundColor = UIColor.brownColor()

popoverController.permittedArrowDirections = UIPopoverArrowDirection.init(rawValue: 0)
popoverController.sourceRect = CGRectMake(width/4, hieght/4, width/2, hieght/2);

回答13:

In swift 3, you can build a UIPopoverArrowDirection extension for this:

extension UIPopoverArrowDirection {
    public static var noArrow: UIPopoverArrowDirection {
        return UIPopoverArrowDirection(rawValue: 0)
    }
}

and the you can do:

popoverPresentationController!.permittedArrowDirections = .noArrow

回答14:

Try this one

[popOverController presentPopoverFromRect:CGRectMake(0, 0, 30, 40) inView:popOverContentView permittedArrowDirections:0 animated:NO];

回答15:

I use popover to show menu depending on touch coordinate. In this case popover uses maximum height of self.view

CGRect popeverFrame = CGRectMake(touchPoint.x, touchPoint.y, 0, 0);
[self.popover presentPopoverFromRect:popeverFrame
                              inView:self.view
            permittedArrowDirections:UIPopoverArrowDirectionAny
                            animated:YES];

But when I use 0-direction. Popover rectangle doesn't set it height to maximum and can only be set by appropriate property.

CGRect popeverFrame = CGRectMake(touchPoint.x, touchPoint.y, 0, 0);
[self.popover presentPopoverFromRect:popeverFrame
                              inView:self.view
            permittedArrowDirections:UIPopoverArrowDirectionAny
                            animated:YES];

Hope this will help: Help with UIPopOverController size

回答16:

To make a pop over direction none and make it to appear in center of the view controller :

let PopSrnVar = popoverPresentationController
let ConRctVar = view.frame
PopSrnVar!.sourceRect = CGRectMake(ConRctVar.width/4, ConRctVar.height/4, ConRctVar.width/2, ConRctVar.height/2)
// To make arrows as none
PopSrnVar!.permittedArrowDirections = UIPopoverArrowDirection()

回答17:

A simple solution in SWIFT:

popover!.permittedArrowDirections = nil
