"2x" Button reduces clarity - ios

I have an iPhone app that looks good on retina iphones but when it's on an iPad and someone taps the "2x" button in the corner, the app is expanded and thus the quality is reduced.
What's the best way to handle this? Can I use higher quality images somehow?

When you create an app, there are two options, You create a separate interface for the iPad, or you don't.
If you create a separate interface, it will load up, and there will be no 2x option.
If your app does not have an iPad interface, the iPad will display the iPhone screen, and 2x will just stretch the pixels.
So if you want a clear iPad app, you will have to create a iPad interface -
Separate storyboard - If you have used storyboard.
Separate Xib - If you have used XIB
Different frames etc - If you have used code to create the UI.
Hope it helps.

As far as I know, there is nothing you can do in this situation. The 2x button takes the retina iPhone screen and simply scales it up.

iOS: How to use LaunchScreen.storyboard for multiple screen sizes?

I use to have a launch screen image for every screen size, and the image differs from iPhone to iPad.
The image also is optimized to look perfect on any screen, because the launch screen USED TO have the possibility to put image for each size.
But Now that it is deprecated. We have to use LaunchScreen.storyboard and I don't know how to achieve the same thing with it!
How can I use this "good for nothing" storyboard to show different image for every device out there (iPhone, iPad, Portrait, Landscape). And why isn't this documented at Apple's ?
Thank you.

Add second Splash Screen for iPad

My app is available for both iPhone and iPad. But in LaunchScreen storyBoard I'm able to enter only one picture(for example for iPhone), this picture looks ridiculous on iPad.
But we also can't create custom class for this screen to display different pictures for different devices, how is it possible to show 2 different pictures in LaunchingScreen in one app for both iPhone and iPad?
Start by adding an image set. Then use this image set from you storyboard.
I think your answer is in iOS Human Interface Guidelines take
different size of images in image assets.

Do I need iPhone/iPad specific button images in my case?

Here is my situation: I have a simple app with some buttons that are images. I have the image set in xcode using the menu on the right (i simply click the button and pick the image I want from the dropdown). I created them using a simple image program so they look somewhat glossy and nice, but nothing crazy. I also sized them for an iphone screen.
Using some auto layout, I've been able to ensure the layout stays the same and the buttons change size with the size of the iphone. I would like this to be the case with the iPad as well, but I'm worried if they size too big, I'll lose image quality with the button images. I'm very new to layout and coding and have only been doing this development stuff for a little while. What are my options? I figure they are...(and these might not even be possible, throwing them out there):
1) Create two version of the app, one only for iPad and one only for iPhone with different size/quality images for each.
2) Code swift to identify the device and assign the different image accordingly
3) Pick a resolution for the iphone image that when expanded on iPad won't lose much quality
4) I'm overreacting and this isn't a big deal whatsoever since it's just a basic glossy button with some shadowing.
Thank you! Advice/links appreciated.
The better option to add images for both iPhone(retina/non-retina) and iPad(retina/non-retina). Put the high-resolution and original versions of your image in the same location in your application bundle.
Ones you added images same as the below naming format in to your application resources, the application will automatically pick the right one for you.
MyImage.png - Default version of an image resource.
MyImage#2x.png - High-resolution version of an image resource for devices with Retina displays.
MyImage~iphone.png - Version of an image for iPhone and iPod touch.
MyImage#2x~iphone.png - High-resolution version of an image for iPhone and iPod touch devices with Retina displays.
MyImage~ipad.png - Version of an image for iPad.
MyImage#2x~ipad.png - High-resolution version of an image for iPad devices with Retina displays.

How/whether to make a universal storyboard in Xcode

When creating a storyboard file in Xcode, you must select if it is for iPhone or iPad. This implies one should always put iPhone and iPad UIs into separate storyboards. Is this true?
My app has multiple storyboards. While the Main.storyboard files largely differ between iPhone and iPad, other storyboards are nearly identical. The only difference might be segue being a push on iPhone vs popover on iPad, which can be handled programmatically. It seems awfully silly and redundant to make two storyboards.
So if making one "universal" storyboard, should iPhone or iPad be selected in Xcode? Does it matter?
As of Xcode 6, we can create a single unified storyboard for all the devices.
For more info - Documentation
iOS 8 makes dealing with screen size and orientation much more
versatile. It is easier than ever to create a single interface for
your app that works well on both iPad and iPhone, adjusting to
orientation changes and different screen sizes as needed. Design apps
with a common interface and then customize them for different size
classes. Adapt your user interface to the strengths of each form
factor. You no longer need to create a specific iPad storyboard;
instead target the appropriate size classes and tune your interface
for the best experience.
There are two types of size classes in iOS 8: regular and compact. A
regular size class denotes either a large amount of screen space, such
as on an iPad, or a commonly adopted paradigm that provides the
illusion of a large amount of screen space, such as scrolling on an
iPhone. Every device is defined by a size class, both vertically and
horizontally. iPad size classes shows the native size classes for the
iPad. With the amount of screen space available, the iPad has a
regular size class in the vertical and horizontal directions in both
portrait and landscape orientations.
Edit:
It only supports iOS 8(backward compatible applies only for iOS 7) and later.
You've got to create to separate storyboards for each kind of device. If you would delete the iPad storyboard, than your app would use the iPhone's one. You'll realize it when you'll see the 2x button at the bottom of the screen. Everything will be scaled to fit the larger screen - and the graphics would be really bad.
The only suitable workaround is to copy-paste everything from your iPhone Storyboard to iPad storyboard. Just follow the next steps:
Open iPhone.storyboard,
Press CMD+A,
Press CMD+C,
Switch to iPad.storyboard,
Press CMD+V,
You'll see, that all the screens, segues, properties and actions are transferred to your new storyboard. All that you have to do is to fix the frames of all your elements so that they'll suit new screen sizes.
And don't forget, that a good iPad application shouldn't be the same as the iPhone version. There are a lot of cool things which you can do with iPad!

converting story board from iphone to ipad

I have a storyboard for my iphone version of my app and I want to have the same storyboard for my ipad version (only bigger). My story board only has text and buttons is there anyway I can just convert the whole thing and increase the size by 2, or do have to resize everything manually?
You really need to do more than just resize you know. iPad users don't generally enjoy running iPhone apps at double size on the iPad and it sounds like that's what you're proposing to do.
In your storyboard you can drag and drop from your iPhone screens to iPad to get all of the elements into the iPad storyboard. Then maybe you will tweak a bit to make it more iPad friendly.
As far as I know, you will need to create a new storyboard and set that as the storyboard for iPad (app settings). You will then need to create the content manually (you can copy and paste the objects and use the existing controller classes though (will need to wire up the objects).
