I am trying to present popover with UIPopoverPresentationController class on the iPhone.
I need to present navigation controller inside the popover. So I do the following:
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
viewController.preferredContentSize = size;
navigationController.modalPresentationStyle = UIModalPresentationPopover;
self.currentPopoverController = navigationController.popoverPresentationController;
self.currentPopoverController.backgroundColor = [UIColor commonApplicationBgColor];//My common app blue color
self.view.alpha = 0.7;
[self presentViewController:navigationController animated:YES completion:nil];
It is working, but arrow colour is differ from the popover navigation bar background colour. I checked they use the same [UIColor commonApplicationBgColor], but it looks like arrow colour is darker. Tried setup alpha for self.currentPopoverController.backgroundColor, but it is still has wrong color.
Please check image:
if you don't want arrow then you can pass 0 to permittedarrowdirection like,
[popoverController presentPopoverFromRect:YOUR_RECT
inView:self.view
permittedArrowDirections:0
animated:YES];
Update :
you can set like,
popover = [[UIPopoverController alloc] initWithContentViewController:contentViewController];
popover.backgroundColor = contentViewController.view.backgroundColor;
set bacground color to popovercontroller.
Update 2 :
myPopoverViewController.modalPresentationStyle = UIModalPresentationPopover;
[self presentViewController:myPopoverViewController animated: YES completion: nil];
// Get the popover presentation controller and configure it.
UIPopoverPresentationController *presentationController =
[myPopoverViewController popoverPresentationController];
presentationController.permittedArrowDirections =
UIPopoverArrowDirectionLeft | UIPopoverArrowDirectionRight;
presentationController.sourceView = myView;
presentationController.sourceRect = sourceRect;
presentationController.backgroundColor = [UIColor grayColor]; //set your expacted color here.
Hope this will help

I am struggling to understand why the following views, one for CABTMIDILocalPeripheralViewController and the other for CABTMIDICentralViewController show different behaviour in my iOS app (written in Objective-C)
- (IBAction)configureCentral:(id)sender
{
CABTMIDICentralViewController *viewController = [CABTMIDICentralViewController new];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:viewController]; // this will present a view controller as a popover in iPad and modal VC on iPhone
viewController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self
action:#selector(doneAction:)];
navController.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popC = navController.popoverPresentationController;
popC.permittedArrowDirections = UIPopoverArrowDirectionAny;
popC.sourceRect = [sender frame];
viewController.preferredContentSize = CGSizeMake(320., 400.);
popC.backgroundColor = [UIColor darkGrayColor];
viewController.view.backgroundColor = [UIColor darkGrayColor];
UIButton *button = (UIButton *)sender;
popC.sourceView = button.superview;
[self presentViewController:navController animated:NO completion:nil];
}
Opens a popup view on an iOS device, which does not show any 'done' button to dismiss the view.
CABTMIDICentralViewController shows no button to close/dismiss the view
While on an iPad tapping outside the view will close it, on an iPhone the view takes the size of the screen and exiting/closing becomes impossible.
The same code used for the CABTMIDILocalPeripheralViewController works as expected.
- (IBAction)configureLocalPeripheral:(id)sender
{
CABTMIDILocalPeripheralViewController *vController = [[CABTMIDILocalPeripheralViewController alloc] init];
UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:vController];
vController.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemDone
target:self
action:#selector(doneWithPeripheral:)];
navController.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popC = navController.popoverPresentationController;
popC.permittedArrowDirections = UIPopoverArrowDirectionAny;
popC.sourceRect = [sender frame];
vController.preferredContentSize = CGSizeMake(320., 400.);
popC.backgroundColor = [UIColor grayColor];
vController.view.backgroundColor = [UIColor darkGrayColor];
UIButton *button = (UIButton *)sender;
popC.sourceView = button.superview;
[self presentViewController:navController animated:NO completion:nil];
}
CABTMIDILocalPeripheralViewController has a 'done' button
What is going wrong here? I have tested to make the views wider to see whether available space in the Navigation bar would have caused this.
Thanks.
I am trying to present a popover controller but for some reason I can't get the width/height of the popover to set correctly. Here's the code I am using:
Here's my code:
UIStoryboard* myStoryboard = self.storyboard;
ScenarioPopOver* popOver = (ScenarioPopOver*)[myStoryboard instantiateViewControllerWithIdentifier:#"scenarioPopover"];
popOver.modalPresentationStyle = UIModalPresentationPopover;
[self presentViewController:popOver animated:YES completion:nil];
// configure the Popover presentation controller
UIPopoverPresentationController *popController = [popOver popoverPresentationController];
popController.permittedArrowDirections = UIPopoverArrowDirectionUp;
popController.delegate = self;
// in case we don't have a bar button as reference
popController.sourceView = self.view;
popController.sourceRect = CGRectMake(self.view.center.x - 25.0, 10.0, 50.0, 50.0);
But the popover keep coming out like this:
Just in case someone stumbles across this issue. I was trying to set the preferredContentSize on the UIPopoverPresentationController and not the UIViewController within it. Correct code is below:
UIStoryboard* myStoryboard = self.storyboard;
ScenarioPopOver* popOver = (ScenarioPopOver*)[myStoryboard instantiateViewControllerWithIdentifier:#"scenarioPopover"];
popOver.modalPresentationStyle = UIModalPresentationPopover;
[self presentViewController:popOver animated:YES completion:nil];
// configure the Popover presentation controller
UIPopoverPresentationController *popController = [popOver popoverPresentationController];
popController.permittedArrowDirections = UIPopoverArrowDirectionUp;
popController.delegate = self;
popOver.preferredContentSize = CGSizeMake(400.0, 300.0);
// in case we don't have a bar button as reference
popController.sourceView = self.view;
popController.sourceRect = CGRectMake(self.view.center.x - 150.0, 10.0, 0.0, 0.0);
I want present a UINavigationController like the image above, I use
nvc.modalPresentationStyle = UIModalPresentationFormSheet;
But I can't change the controller's size.
This is how I did:
UIViewController *vc = [[UIViewController alloc] init];
vc.view.backgroundColor = [UIColor grayColor];
UINavigationController *nvc = [[UINavigationController alloc] initWithRootViewController:vc];
nvc.modalPresentationStyle = UIModalPresentationFormSheet;
nvc.view.frame = CGRectInset(self.view.bounds, 20, 20);
[self presentViewController:nvc animated:YES completion:nil];
But the present viewController is still full screen.
May be you can use preferredContentSize as follows:
nvc.modalPresentationStyle = UIModalPresentationFormSheet;
nvc.preferredContentSize = CGSizeMake(width, height);
Like,
nvc.preferredContentSize = CGSizeMake(300, 600);
OR
In Presented viewController's viewDidLoad method write below code:
self.preferredContentSize = CGSizeMake(width, height);
Edit:
Select your viewController or xib and set size property to Freeform.
Enable user preferred explicit size in Content size in attributes inspector.

I'm writing iOS FFI methods for Kony application. In that, I'm presenting a viewcontroller with clear backgroundcolor. But, it's showing a white background view. I'm not using storyboars, I'm designing views in code only. In the newviewcontroller viewdidload, I set the self.view background color to clearcolor.
Here's what I have tried,
NewViewController *newVC = [[NewViewController alloc]init];
newVC.providesPresentationContextTransitionStyle = YES;
newVC.definesPresentationContext = YES;
self.modalPresentationStyle = UIModalPresentationCurrentContext;
[KonyUIContext onCurrentFormControllerPresentModalViewController:newVC animated:YES];
I'm new to KonyUIContext, how can I fix this?
Can anyone help me on this?
Try this code... It works perfectly for me....
MyViewController *modalViewController = [[MyViewController alloc] init];
modalViewController.modalPresentationStyle = UIModalPresentationOverCurrentContext;
[KonyUIContext presentViewController:modalViewController animated:YES completion:nil];
try this , You just need to set backgroundcolor to clear color of your viewcontroller's view .
NewViewController *newVC = [[NewViewController alloc]init];
newVC.view.backgroundColor = [UIColor clearColor];
newVC.providesPresentationContextTransitionStyle = YES;
newVC.definesPresentationContext = YES;
self.modalPresentationStyle = UIModalPresentationCurrentContext;
[KonyUIContext onCurrentFormControllerPresentModalViewController:newVC animated:YES];
Hope this Helps!
How do I make my flip animation transparent so the view behind it is shown through?
Here's some of my code:
EditInfoViewController *editController = [[EditInfoViewController alloc] initWithNibName:#"EditInfoViewController" bundle:nil];
editController.delegate = self;
UINavigationController *editNavController = [[UINavigationController alloc] initWithRootViewController:editController];
editNavController.modalPresentationStyle = UIModalPresentationCurrentContext;
editNavController.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal;
[self.navigationController presentModalViewController:editNavController animated:YES];
A picture is worth 1000 words (this was taken during the flip animation):
