Full Screen Custom Popover issue in iOS7 and iOS8 - ios

Question

I am developing an app for iPad only. In which in for one functionality i want to display FullCustom Popover.
For that my code is as below:-
DuplicateViewController *viewControllerForPopover =
[self.storyboard instantiateViewControllerWithIdentifier:#"DuplicatePopoverVC"];
viewControllerForPopover.arr_studentDetail = self.arrStudentDetail;
viewControllerForPopover.dictSelectedProg = dictSelectedProgram;
self.popover = [[UIPopoverController alloc]
initWithContentViewController:viewControllerForPopover];
[self.popover setPopoverContentSize:CGSizeMake(self.view.frame.size.width, self.view.frame.size.height)];
viewControllerForPopover.modalPresentationStyle = UIModalPresentationFullScreen;
[self.popover setBackgroundColor:[[UIColor darkGrayColor] colorWithAlphaComponent:0.4]];
[self.popover presentPopoverFromRect:self.view.bounds inView:self.view permittedArrowDirections:0 animated:YES];
I set popover size and tried with other option but can't make it full screen.
ViewDidLoad -> DuplicateViewController
[view_main.layer setBorderWidth:5.0f];
[view_main.layer setCornerRadius:25.0f];
[view_main.layer setBorderColor:[UIColor colorWithRed:(29.0f/255.0f) green:134.0f/255.0f blue:140.0f/255.0f alpha:1.0f].CGColor];
But while running App, It display as below:-
Please help me to display full screen Popover. Thank you so much in advance.

Answer 1

create two classes
the first one should inherit UIPopoverController
the second one should inherit UIPopoverBackgroundView
for example:
CustomUIPopoverController.h
#interface CustomUIPopoverController : UIPopoverController
CustomUIPopoverController.m
#implementation CustomUIPopoverController
- (id)initWithContentViewController:(UIViewController *)viewController {
self = [super initWithContentViewController:viewController];
if (self) {
self.popoverBackgroundViewClass = [CustomUIClearPopoverBackgroundView class];
[self setPopoverContentSize:viewController.view.frame.size];
}
return self;
}
#end
CustomUIClearPopoverBackgroundView.h
#interface CustomUIClearPopoverBackgroundView : UIPopoverBackgroundView
CustomUIClearPopoverBackgroundView.m
#import "CustomUIClearPopoverBackgroundView.h"
#implementation CustomUIClearPopoverBackgroundView
#pragma mark - no arrow
+ (CGFloat)arrowHeight {
return 0;
}
+ (CGFloat)arrowBase {
return 0;
}
- (CGFloat)arrowOffset {
return 0;
}
- (void)setArrowOffset:(CGFloat)arrowOffset {
}
- (UIPopoverArrowDirection)arrowDirection {
return 0;
}
- (void)setArrowDirection:(UIPopoverArrowDirection)arrowDirection {
}
#pragma mark - no margins
+ (UIEdgeInsets)contentViewInsets {
return UIEdgeInsetsZero;
}
#pragma mark - fully transparent (default is 0.15)
+(BOOL)wantsDefaultContentAppearance {
return NO;
}
- (void)willMoveToWindow:(UIWindow *)newWindow {
[super willMoveToWindow:newWindow];
// hide shadow image view
[self.superview.subviews[0] setHidden:YES];
}
#end
I used this but I don't like it very much.
the second option is to create a container view and hide/show it as you like.
this way it's a pure view controller and you don't need to mess with popup stuff
to create the transparency, make your container view background = clear, the view controller view background color = clear, and add a semi-transparent button in the size of the view controller for the semi-transparent black background. on click of the button close the window (= same effect as tapping the popup background)
