How to delete the Popover arrow of the iPad and its frame border

- (void) viewWillAppear: (BOOL) animated
{
 [super viewWillAppear: animated];

 UIView* v = self.view .superview;
 NSLog( @"%@", NSStringFromClass( [v class]) ); // this should print UIView

 v = v.superview;
 NSLog( @"%@", NSStringFromClass( [v class]) ); // this should print UIPopoverView

 [[v.layer.sublayers objectAtIndex:0] removeFromSuperlayer];
} 
I think you can try to add your own layer to render the background/border the way you want.
 

Basically these are two problems :

>Is there a way to delete the black border of the popover?

If it is not possible, can you suggest a way to display a UIView (popover) on the top of the screen without arrows and borders (maybe a light transparent border) on the iPad, please? Thank you very much.

And I think ModalView is not a suitable option because it cannot be resized and cannot be dismissed by clicking the external modal view.

AFIK has no built-in way to specify "no arrow", or popup without borders.

This is a hack, but it is basically effective. It is managed by the popup controller In the context of the view controller, during viewWillAppear:, get the pop-up window and delete the first layer, which is the content of the arrow and border:

- (void ) viewWillAppear: (BOOL) animated
{
 [super viewWillAppear: animated];

 UIView* v = self.view.superview;
 NSLog( @"% @", NSStringFromClass( [v class]) ); // this should print UIView

 v = v.superview;
 NSLog( @"%@", NSStringFromClass( [v class] ) ); // this should print UIPopoverView

 [[v.layer.sublayers objectAtIndex:0] removeFromSuperlayer];
}

I think you can try to add you Your own layer, render the background/border the way you want.
