I have tried to change it's size manually (by dragging) and still not working.
You can set its Content size to whatever you want.
On iOS 13 a "Modal" segue will show the presenting controller that way by default.
If you want the view controller to occupy the whole screen, set "Full Screen" on the "presentation" setting of any segue entering that controller.
Segue Settings
If your view presents programmatically (not via storyBoard), have this in mind:
From XCode 11 and up, when you build for iPad you have to add "modalPresentationStyle = .fullScreen" to get full screen views, not square ones. As follows:
let vc = UIViewController()
vc.modalPresentationStyle = .fullScreen
self.present(vc, animated: true, completion: nil)
If you want transparency on the new viewController, you can write ".overFullScreen", as follows:
let vc = UIViewController()
vc.modalPresentationStyle = .overFullScreen
self.present(vc, animated: true, completion: nil)

I'm a beginner developing iOS apps using swift in Xcode.
[embarrassment]
I would like to know how to display tabBar on the screen after the transition by button.
If you press the button in FistViewController in the image below, you will go to nextViewController on the right side. I would like to know how to display the tabBar in nextViewController as well. (If you press the button to transition through the screen, the nextViewController will not display the tabBar.)
When you present a view controller modally, its presentation style will be "Full Screen" by default.What you need to do is change your modalPresentationStyle
guard let VC = self.storyboard?.instantiateViewController(withIdentifier: "yourVCName") else {
return
}
self.definesPresentationContext = true
VC.modalPresentationStyle = .overCurrentContext
self.present(VC, animated: true, completion: nil)
I am trying to change the transition animation in navigation controller to load a new UIView controller from bottom to top, using Segue. I believe it will not be too hard to implement but may be I am not able to understand it.
My first attempt was to use Hero library but it does not work for some reason.
The answers found so far were only in Objective-C
You can try this solution to present your new controller modally.
let storyboard = UIStoryboard(name: "Storyboard Name", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "Controller Name
")
self.present(controller, animated: true, completion: nil)
I created UITabBarController programmatically in AppDelegate with 4 view controllers(using .xib). When user tap some button on ViewController (VC-A) it present another VC (VC-B) and covered tabbar. So I want to VC-B has a tabbar on the button.
I tried to add VC-B as a child of tabbarcontroller. I tried to .present(vc) and .show(vc) on both: VC-A and VC-A.TabBarController
Creating controllers in AppDelegate:
let controllers = [tabViewController1,tabViewController2,tabViewController3,tabViewController4]
tabBarController.viewControllers = controllers
window?.rootViewController = tabBarController
presenting in VC-A
self.tabBarController?.present(controller, animated: false, completion: nil)
right click and drag from tabbar controller in storyboard to VC-B. that should create a tab on the bottom of your VC-A and VC-B to go back and forth without having to implement any backend code unless you want to animate
The solution is to embed every VC in navigationController and then add to TabBarController.
let vc1 = ViewController1()
let navController1 = UINavigationController(rootViewController: vc1)
navController.isNavigationBarHidden = true
let controllers = [navController1, navController2, navController3, navController4]
tabBarController.viewControllers = controllers
window?.rootViewController = tabBarController
Then call
self.navigationController?.pushViewController(controller, animated:
true)
To diplay VC with tabbar
I will press the red login button at the bottom of the picture and try to log in.
login button => "로그인"
After that, log in.
let moreVC = self.storyboard?.instantiateViewController(withIdentifier: "MoreViewController") as! MoreViewController
moreVC.definesPresentationContext = true
moreVC.modalPresentationStyle = .fullScreen
let navController = UINavigationController(rootViewController: moreVC)
self.present(navController, animated: true, completion: nil)
If the login proceeds without error, the above code will be called to display the screen when the login is completed.
If the flow proceeds as the code above, this screen appears.
The screen shown is not fullscreen, and the tabbar at the bottom is gone. The screen I want is the screen below.
How can I present a tab bar when presenting the screen?
I am having an issue with using the .overCurrentContext modalPresentationStyle on a tvOS view controller:
let vc = UIStoryboard(name: "", bundle: Bundle.main).instantiateInitialViewController() //representative of actually presented VC
vc.modalPresentationStyle = .overCurrentContext
present(vc, animated: true, completion: nil)
On the presented view controller, pressing the menu button ceases to return to the presenting view controller. This also occurs when setting it to .overFullScreen and .blurOverFullScreen. However, I am having no such problem when setting it to .currentContext or .fullScreen. Is there anything particular that needs to be used when using certain UIModalPresentationStyle's?
let vc = UIStoryboard(name: "", bundle: Bundle.main).instantiateInitialViewController() //representative of actually presented VC
vc.modalPresentationStyle = .overCurrentContext
self.definesPresentationContext = true //*** adding this line should solve your issue ***
self.present(vc, animated: true, completion: nil)
So what's going on here? The definesPresentationContext property was added in iOS 8, and the documentation states the following:
When a view controller is presented, iOS starts with the presenting view controller and asks it if it wants to provide the presentation context. If the presenting view controller does not provide a context, then iOS asks the presenting view controller's parent view controller. iOS searches up through the view controller hierarchy until a view controller provides a presentation context. If no view controller offers to provide a context, the window's root view controller provides the presentation context.
If a view controller returns YES, then it provides a presentation context. The portion of the window covered by the view controller's view determines the size of the presented view controller's view. The default value for this property is NO.
By setting definesPresentationContext to YES you ensure that the controller to be presented is presented within the bounds of the original view controller.
I simply want to present a small option dialog over an existing main UIViewController/UIView , so that on an IPad I would see a small Dialog and in the Background I will see the Main View.
I managed to show a UIViewController/UIView in a modal view style as follow:
func showoptions(){
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewControllerWithIdentifier("Options") as! UIViewController
controller.modalPresentationStyle = UIModalPresentationStyle.Popover
let popoverPresentationController = controller.popoverPresentationController
// result is an optional (but should not be nil if modalPresentationStyle is popover)
if let _popoverPresentationController = popoverPresentationController {
// set the view from which to pop up
_popoverPresentationController.sourceView = self.view;
//_popoverPresentationController.sourceRect = CGRectMake(60, 100, 500, 500)
//_popoverPresentationController. .setPopoverContentSize(CGSizeMake(550, 600), animated: true)
//_popoverPresentationController.sourceView.sizeToFit();
// present (id iPhone it is a modal automatic full screen)
self.presentViewController(controller, animated: true, completion: nil)
}
}
But I have still some issues:
1. Howto get rid of the arrow shown at the border.
2. Howto size this modal view. It is shown to small and I would like to fit it to the largest controls in the UIControllerView/UIView.
any help ?
Try changing _popoverPresentationController.permittedArrowDirections to empty option set
Change controller.preferredContentSize to match your desired size
I needed something similar and ended up presenting a view controller as a modal with a transparent background over the current context. There I made a smaller opaque UIView with what I wanted.
