Seeing black bars at the top and bottom of the iPhone X Simulator
(11 answers)
Closed 5 years ago.
We updated today to xCode 9 and our Visual Studio for Xamarin Development.
I tested my apps on iPhone X and it has a spaces on upper and lower portion. Any idea and work around to update the app?
using Visual Studio Xamarin Forms.
You need to build against the iOS 11 SDK and have a launch storyboard or your app will run in compatibility mode on iPhone X, like you're seeing.
Enabling native resolution on the iPhone X may cause other issues that you'll need to work through. You should layout your views/constraints to the safe areas to solve those issues.

I just wanted to ask why my app is starting with a too small size on devices other than iPhone 4s on my simulator? Is there something wrong related to the constraints I set or general project difficulties?
You must set your launch images. At least set them for iphone 6 and you should solve the issue

Black bars on launch screen on iPhone5 (and iPhone6)
(2 answers)
Closed 7 years ago.
Just got an iPhone 6S and started adjusting my project to it.
Somehow, when compiled and debugged on my iPhone, the view seems much smaller (like 4s).
Xcode: 7.1.1
iOS: 9.0.1
IPHONE: 6S
Anyone knows that went wrong?
Thanks,
You need to include launch images for all the iPhone sizes if you want the app to use the native screen size. The easiest way to do this is to migrate your launch images into an asset catalog.

How to enable native resolution for apps on iPhone 6 and 6 Plus?

Closed 8 years ago.
When running one of my apps on the iPhone 6, I've noticed the nav bar height of my app is taller than the nav bar height of a system app (ex Settings). While looking at some third party apps, I've noticed some apps have the same nav bar height as system apps (Twitter), and some apps have the same problem I do (Instagram).
This makes me believe that some of the apps are explicitly optimizing for iPhone 6, and some apps are just being scaled by the platform. Is there a specific way to optimize for iPhone 6?
This isn't an iOS 8 problem, as I've ran my app on an iPhone 5 running iOS 8 and the nav bars matched.
You have to provide launch images for iPhone 6 and 6+ (or a launch xib file). See here: How to enable native resolution for apps on iPhone 6 and 6 Plus?

I am currently working on an iOS app and using new feature Use Size Classes in Xcode 6 with Swift language. Everything seems to work (elements are placed correctly for different screen sizes), but when I run my app on iPhone 5s(4 inch), the screen shown as 3.5 inch iPhone (The status bar would be placed where it would be on a 3.5 inch iPhone).
I have tried a lot to fix this by settings constraints even though it just keeps treating me the display as 3.5 inch display.
Extra info:
iPhone 5s device,
iOS 7,
Xcode 6 GM and
Single View application.
The issue happens even without making any changes to a fresh project.
Thanks for reading.

How to deal with iPhone 5 screen size?
The iPhone 5 has a bigger screen than all previous models (4 inches instead of 3.5). How will this affect current apps that were designed for the original screen when they're displayed on the iPhone 5?
I ask because I am withholding the launch of a new app of mine and am wondering if I need to make modifications for iPhone 5 screen-wise.
Existing apps will run in a compatibility mode, and will be presented in a "letterbox" format.
