I want to present a UIViewController in iPhone and iPad both as same as we present in iPad using UIModalPresentationFormSheet but i also want to give good amount of curve on the edges like cornerRadius. I can do it using UIView and animate it from bottom to top but i want to do using UIViewController
It is not possible using the built-in frameworks.
Docs:
In a horizontally compact environment, this option behaves the same as
UIModalPresentationFullScreen.
You'll have to write custom code to show a view modally that doesn't fully obscure the underlying view.

How do I allow one subview of my view controller to autorotate on an orientation change, but keep the others static. I'm trying to get an effect similar to the native camera app where the capture and switch cameras buttons (along with all the others) stay in their locations and just rotate accordingly. The SnapChat app also does this where the UI layer that pops up after you take a photo autorotates but the other views do not.
I seemed to be able to get close following the answers here: Disable autorotate on a single subview in iOS8, however, while this prevents them from rotating, it jumbles up their positions.
I think you have to use
(i) autolayout to set constraints on view by fixing its position or width height.
for setting orientation for portrait and landscape you have to use size classes
(ii) Another trick is you can use UIViewController to fix orientation using its mask orientation delegate. then add it add child of other UIViewController
When device turn to landscape, some controls go out of viewController, and I can't drag it to viewController.
Like you can see on your screenshot you have invalid constraints, this can be a problem. If you are using storyboard or xib simple use sizeclass to define specific constraints for portirat and landscape mode. Go and checkout Apple guidelines for adaptive UI https://developer.apple.com/design/adaptivity/
If you are using Storyboard with Autolayouts(constraints),Check once your constraints,Or if you are implementing via coding, You can change frame when device is rotating.
I have a custom view which needs to be displayed on all the iPhone devices(4, 4S, 5, 5S, 6 and 6 Plus). When creating the custom view XIB, I have mentioned it as "Inferred" but it is not resizing for iPhone 6 and iPhone 6 Plus devices. I am not able to figure out the issue. I am confused on what would be actual differences between "Inferred" and "Freeform". Can someone please explain the differences?
Inferred resizes the scene according to its parent scene. For example if you have a scene that is the size of an iPad and then you add a new scene to your storyboard and create a segue to it, it will automatically resize to the same size as the iPad scene (where the segue originates from).
Freeform ignores the above rule and you're able to size it as you see fit, in the utility pane on the right.
Both of these however have nothing to do with how the view is displayed and sized on actual devices. For that you need to use auto layout and constraints. Or springs and struts. Some even do it in code if they need more flexibility.
“Inferred” is the default setting for storyboards and it means the scene will show a navigation bar when it’s inside of a navigation controller, a tab bar when it’s inside of a tab bar controller, and so on. You could override these settings if you wanted to, but keep in mind they are here only to help you design your screens. The Simulated Metrics aren’t used during runtime, they’re just a visual design aid that shows what your screen will end up looking like.
"FreeForm" Usually you use the freeform property when you add the view controller as a child to another view controller programmatically 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.
I have an app in which its my intention to change screen orientation as the user rotates the iPad. In my app I have several popovers.
The potential issue I'm concerned about is one of my popovers covers most the screen so if rotation changes, I'd want the popover to change view dimensions. Is it possible whilst a view is open or will i have to close it and reopen it.
Thanks
If your using a UIPopoverController the standard behaviour it does is to hide the popover when you rotate. It try's to then reposition it for you, this tends not to work so you want to use popoverController:willRepositionPopoverToRect:inView to set your new position and resize as needed.
If you use setPopoverContentSize:animated: it will re size for you, If your using autolayout you'll want to use preferredContentSize in the content viewController.
Apple Doc:
If the user rotates the device while a popover is visible, the popover
controller hides the popover and then shows it again at the end of the
rotation. The popover controller attempts to position the popover
appropriately for you but you can also implement the
popoverController:willRepositionPopoverToRect:inView: method in the
popover delegate to specify a new position.
In the below image, what is the UI control used to create the "Other Network" dialog? We need to create a similar non-full-screen popup.
I think what you're looking for is a UIModalPresentationFormSheet.
From Apple's UIViewController documentation reference
UIModalPresentationFormSheet
The width and height of the presented view are smaller than those of the screen and the view is centered on the screen. If the device is in a landscape orientation and the keyboard is visible, the position of the view is adjusted upward so that the view remains visible. All uncovered areas are dimmed to prevent the user from interacting with them.
Available in iOS 3.2 and later.
Declared in UIViewController.h.
See this article for an example Display a view using modalPresentationStyle
It should be a view controller presented modally using UIModalPresentationFormSheet as its modalPresentationStyle.
