I'd like to create a sort of popup view that is displayed in a main controller through custom transitions.
I create the popup viewcontroller into a storyboard and I set its view as freeform, then I resize the view.
My problem is that when I load the view controller using instantiateViewControllerWithIdentifier the view bounds are always reset to full screen.
Here is the code that I'm using, the popUp size should be 100x100, but from this code I get 320X480.
self.popUp = (PopUpViewController*)[storyBoard instantiateViewControllerWithIdentifier:#"Popup"];
NSLog(#"%#",NSStringFromCGRect(self.popUp.view.bounds));
How can I setup a freeform view controller and load it programmatically with the right size?
Solution at Wrong frame value while accessing the view from storyboard in IOS worked for me.
Uncheck the "Resize View From Nib" box in the inspector. That should
give you the correct size for a freeform view controller.

can anybody tell me how to make a viewcontroller like this in the picture, taller x3 than normal view controller. And how does it show the next view controller if you enable the switch button not a segue!
Use the Size Inspector in your storyboard. Set the simulated size to Freeform and change the height as needed:
I am displaying a UIViewController(In NotificationContentExtension) with a child view controller. The parent controller is just adding to its view the view of child controller as subview.
The subview is all built with autolayout and constraints, which renders fine when not embedded in a view controller.
Currently, the parent notification is displayed as big as the parent view controller's view is configured to be in the extension's Info.plist file.
If I provide a height to the childcontroller's view in the parent view it renders as big as the parent but in case I don't initialise its frame, it doesn't render the child controller's view elements.
What I am seeking is to open the controller as big as the child view container's dynamic height make it to be.
To clarify, I believe what you're trying to achieve is a Modal "popup" View Controller than is smaller (in some way) than the View Controller that calls it, similar to the functionality of an Alert View Controller...
Go to your Storyboard and click on the child view controller with the custom height, then open the right pane to view the Size Inspector. I'm assuming here your Simulated Size = "Freeform" with your height and width. This will allow you to actually resize the View Controller in the Storyboard but the view controller will show up fullscreen.
Now click on the Attributes Inspector and in the 4th grouping down, check the box for Content Size "Use Preferred Explicit Size" and type in your simulated size. This will allow your Modal view controller to show up at the exact size you're asking.
To do this programmatically, try this in the calling ViewController's prepare for segue implementation:
destinationVC.preferredContentSize = CGSize(width: 300.0, height: 400.0)
Cheers :)
As I understand and tried, if I change the simulated size of the ViewController in the storyboard it will still stretch its main "view" property to the whole screen.
So my question is when and why should I change this "Freeform" property?
Whenever I needed to make some overlay, I just make the main "view" transparent and create another view on top of that with my content, then I present it I do it as a container.
As I see there is no need for it, And I couldn't find anywhere in Apple documentation about it.
This property is only for simulating a different size.
ViewControllers do not always have to be fullscreen containers, for example View Controller containment, or the new iOS 7 View Controller transitions may lead to a View Controller that's size covers some partial area of the screen.
You would use the 'freeform' mode to change the size in interface builder, so you can simulate what the end size would be, whilst you work with it.
This was answered in the Q UIViewController Freeform size issue: uncheck "Resize View From NIB" in your View Controller's Attributes Inspector and your freeform view controller's view will indeed be decoded at the size you designed in your storyboard.
You are not quite on the right track. If you use Freeform for the size of the view controller, you can specify the desired size of your controller.
Also it's really important how you use the controller, how you set the springs & struts or layout constraints. If you set the springs or constraints to stretch your controller's view to "match" the parent size then the view will be stretched, if not it will keep the size you mentioned but not in all cases. For example if you present the view controller modally and you specify a different explicit size in IB then the view will have this size.
Usually you use the freeform property when you add the view controller as a child to another view controller programatically and you really want to have that fixed size.
If you push the view controller or you present it as modal view controller (and you use the modal presentation styles) then there is no need to use freeform.
Also another use of the freeform property is to preview the actual size of your view controller when is presented as a modal view controller using existent presentation styles.
Another wrongly implementation that I seen before regarding the size of the view controller's view is to check the size in viewDidLoad. Always check the size in viewWillAppear|| viewDidAppear.
I'm presenting a ViewController which has UINavigationController. Is it possible to change the size of whole NavigationViewController just like when showing UINavigationViewController in UIPopOver and the size can be handled with setContentSizeInPopOver. Right now I'm not using UIPopover but I want to change the size of pushed view controller. Setting the frame of UINavigationController of pushed controller in viewDidload isn't helping.
For changing the size of view controller that is to be presented u could use this one
How to present a modal view controller with custom size in center?
Not tested.
Try changing the frame of the view controller view's superview to desired frame just before presenting the navigation controller. Remove all the auto re-sizing masks of the view.
I have created an iPad app containing a popover view embedded in a navigation controller. I like using Storyboard as much as possible, and setting the "Use Explicit Size" in Xcode give me the correct size of my popover on the iPad. But it does not resize the UINavigationController view and its embedded UIViewControllers when viewing the storyboard in Xcode.
This is quite annoying as the size of my view in Xcode does not correspond to the actual size of the popover.
So, my problem is not setting the correct size of the popover (i also know i can do that with code), but I want the views in storyboard to show the actual size of my views.
What is the correct way to create viewControllers embedded in a navigation controller using storyboard?
For the views embedded in the navigation controller, you can change their size in the storyboard by doing the following:
Select the View Controller.
Go to the Attributes Inspector under Simulated Metrics and select Size: Freeform.
Select the View Controller's view.
Go to the Size Inspector and change the width and height.
After that, the view should be sized correctly in the storyboard.
Unfortunately I do not know how to change the size of the navigation controller.
