I've got a UITableView with separator set to Single Line.
On iPhones <= 5s everything looks fine, but on 6 and 6 Plus (device as well as simulator) the separators have a different thickness. It's even worse as they're flickering while scrolling which looks pretty bad. I don't set the height manually, so I have no idea what's causing this.
As you can see, the first two lines are a little bit thicker than the next two. Now if I scroll, they change from thick to thin and back, so it looks like flickering...
The problem is that your app doesn't support native resolution for the iPhone 6 and iPhone 6 Plus. Therefore it gets scaled up which results in the flickering.
You can enable native resolution by adding iOS8 launch images. Then your app will run in the right resolution and this problem will be fixed.
Add
Renders with edge antialiasing: YES
In you .plist file
Aqua is right, the thickness and flickering problems go away if you add iOS8 launch images.
But you don't need to make actual launch images if you are using storyboards. In Xcode, select your overall project and your app target, then under the General tab find App Icons and Launch Images, then in the Launch Screen File popup, just select your storyboard and the thickness/flickering problems go away.

When I run my game on the simulator, specifically on iPhone 6 and iPad Pro, it shows black bar on top of the screen. I have looked the answer up online and have literally tried every single thing and have went through all the answers, but none have worked. My deployment is set to 7.0 and have tried running with setting just set to LaunchImage from asset folder and LaunchImage & LaunchScreen.xib combined. I also do have the right size pictures required in asset including iPhone Retina 4, as well, and that doesn't fix the problem either. Is this just a glitch on the simulator or there is a way around this?
I got it working. For some reason my 2x images were short for the screen size, and had to extend them more. Even though height wise, my images had more length than the screen size.
Hope this helps people. I came across several people who had done everthing right, but still couldn't get it working. I believe it is because image isn't large enough to cover the whole screen
Stretched mode?
Are you providing Default screens in all sizes as suggested in:
Dealing with iPhone 6/6+ startup images
How to Update Your Apps for the 4-Inch iPhone 5 Display
Restoring integrity in Startup screens
Images clipped?
If not running in stretched mode, pick a View Mode best suited for your images, such as Aspect Fill and Scale to Fill, both of which will cover your UIImageView in LaunchScreen.storyboard.
Add Default-568h#2x.png Image with resolution 640x1136.
Make sure 'App Icons and Launch Images' look like below image:
it worked in simulator with iOS 9.
I've come accros a problem with iOS 8 on the iPhone6 and simulator, when you have a UITableViewController with visible separators there seems to be some render problem. Now I could post some code but really if you make just a simple UITableViewController you would have the same problem, just look at eBay and Kijiji they all have this issue.
Normally you wouldn't see this small difference if it only happened once in a blue moon but if you scroll none stop you will see it flash. (less on Ebay since their separators are too close to white but Kijiji is pretty apparent)
Sorry I wanted to post a screenshot but sadly I don't yet have the reputation to do so therefore you will have to try it out yourself's.
Any help would be appreciated
Thanks
The reason why the separators flash is because the app is not designed for the larger displays, and the phone is upscaling the app to fill the larger screen. Since the separator height becomes fractional, the separator line crosses pixel boundaries and becomes antialiased, making it appear wider, lighter, and/or darker than normal.
The answer is to (wait for the developer to) update the app to support the native resolutions of the iPhone 6 and 6 Plus.
You can enable native resolution in your own app by adding launch images or a launch screen file.
Launch images
iPhone 6 requires a portrait launch image of 750x1334.
iPhone 6 Plus requires both portrait (1242 x 2208) and landscape (2208 x 1242) launch images, since it can launch apps in landscape as well as portrait.
Launch screen file (iOS 8)
You can add a launch screen storyboard or nib through Xcode.
In Xcode 6, open the File menu and choose New > File... > iOS > User Interface > Launch Screen.
In the General tab for your project's settings, look for the App Icons and Launch Images section. Set the Launch Screen File to the name of the file you created. This will set the UILaunchStoryboardName key in your Info plist.
Add Renders with edge antialiasing in your plist file, fixed the problem for me.
Remove the Clips Subviews on my custom cell did fix the issue for me.
I have just installed Xcode 4.6.3 to test my OpenGL game (which was developed in Xcode 3) on Retina 4" simulator, and I have got two black bars on the screen's top and bottom.
I have added a Default-568h#2x.png image file with dimension of 640x1136 to my project, when I am testing on the iphone simulator, the Default image is displayed correctly with no bars at all, but once the game starts, the top bar is moved to the bottom of the screen, now I have a sum of two bars at the bottom and no bar at all at the top.
I have done some google search but it seems no one had the same problem before, I am getting this result on the iPhone simulator and have got no iphone5 to confirm this would happen in real device...
I would really appreciate someone could help on this.
Thank you.
I was having a similar problem and the solution I found was to stop using the asset catalog for the Launch Images. That allowed it to revert to using the properly named files it was looking for.
Most of my apps scale up when run on an iPhone 6, but for some reason one of my apps looks like this:
What would cause it to not just scale up and fill the screen?
EDIT: Here are some repro steps:
Create a new project (Single View). Turn off size classes and just use iPhone.
Make the background orange.
Add a yellow UIView subview at (20,20,280,200).
In Xcode you get this:
Now simulate on iPhone 6. You get this:
Why doesn't it just scale up and look normal?
Not sure why this is getting downvoted. It's a legitimate question. And here's the legitimate answer:
Remove the "Launch Screen File" in Projects > General. Xcode 5 did not have this so older apps scale up automatically. Apps created with Xcode 6 get a default Launch Screen file created.
Removing it will make your app scale up on iPhone 6.
I have got the same problem and I managed to solve it by adding constraints to my ViewController in the storyboard.
Make sure that you clicked the ViewController of your scene. They yellow button in the this screenshot.
Click Editor-> Resolve Auto Layout issues -> Add Missing Constraints
Now you will find that the background image is scaled up to fill iPhone 6 or iPhone 6 plus.
Note that this solution works for me even if I did not provide any launch screen file.
I had the same issue. Searching for an answer, most of them mention the launch image. To me, what did the trick, was that I first enabled launch image for iOS8.0 and later in Xcode, which requires the native resolution sizes for 4.7" and 5.5". Adding these sizes didn't help, but when I re-disabled them, it started working!
If you do have any launch image, you will need launch images for all appropriate sizes. I was doing a minor update to an app, and it was not showing correctly on the iPhone 6 simulator. I created four launch images (.png files). Since the app should still run on iOS 7, I apparently could not use an asset catalog. I gave the images the correct names, and all is good.
Image sizes and names may be found here:
Sizes and Naming of Launch Image for iPhone app in iOS8
My views in Xcode (Xcode 6) are all oddly sized (some tall, some short) and are looking very out of place when I run them in the emu. Ill show you some pictures as I'm not doing a very good job at explaining it.
As you can see, theres a white part at the bottom which is un-fillable and the content (which should be under the nav-bar) is being shown perfectly in the emu.
Any ideas as to what is causing this?
Is it a bug in Xcode 6?
Incorrect or missing launch images will cause this behavior. Remove your existing launch images or add the correctly sized launch image for iPhone 5S.
