UIImagePickerController inside UIPopoverController doesn't show Cancel button on iOS7 - ios

Question

I'm using UIImagePickerController inside a UIPopoverController to select image just from photo albums. When I launch app on device running iOS 8, the Cancel button on the top right of the pop over appeared normally like this:
But when I launch the app on device running iOS 7, the Cancel button disappeared:
The code I used to show the picker:
UIImagePickerController *pickerController = [[UIImagePickerController alloc] init];
[pickerController setSourceType:UIImagePickerControllerSourceTypePhotoLibrary];
pickerController.delegate = self;
_popOver = [[UIPopoverController alloc] initWithContentViewController:pickerController];
_popOver.delegate = self;
pickerController.navigationBar.tintColor = [UIColor redColor];//Cancel button text color
[pickerController.navigationBar setTitleTextAttributes:#{NSForegroundColorAttributeName: [UIColor blackColor]}];// title color
if (isImage) {
[pickerController setMediaTypes:#[(NSString*)kUTTypeImage]];
} else
[pickerController setMediaTypes:#[(NSString*)kUTTypeMovie]];
[_popOver presentPopoverFromRect:CGRectMake(1024/2, 768/2, 1, 1) inView:self.view permittedArrowDirections:0 animated:YES];
What can I do to show that Cancel button on iOS7? My app design doesn't allow user to dismiss the popover by tapping anywhere outside the popover view.
Thank you.

#JozoL Write the Below Code this works
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated {
UINavigationItem *pickerNavBarTopItem;
// add done button to right side of nav bar
UIBarButtonItem *doneButton = [[UIBarButtonItem alloc] initWithTitle:#"Cancel"
style:UIBarButtonItemStylePlain
target:self
action:#selector(doSomething)];
UINavigationBar *bar = navigationController.navigationBar;
[bar setHidden:NO];
pickerNavBarTopItem = bar.topItem;
pickerNavBarTopItem.rightBarButtonItem = doneButton;
}
-(void)doSomething{
}

For swift2.x you can try below code, Its work for me
pickerController.navigationBar.tintColor = UIColor.blueColor()

Answer 3

In my case, UIImagePickerController was not showing its cancel button
. So I tried adding this line to code:
pickerController.navigationBar.barStyle = UIBarStyleDefault;
And this worked for me.Try setting color of Cancel button like this
pickerController.navigationBar.tintColor = [UIColor blackColor];
Try using this code and let me know if it helps you.
