I have been desperately trying to add my images into the App Icon set in Xcode but it does not only is allowing me to add in my 960x670 image, then it complains that it does not fit the size dimensions. It does not allow me to place my 120x120 image and others that fit the size dimensions.
By the way, my method of adding in the images is first dragging them into assets.xassets (the general images folder) and then opening the AppIcon set and trying to drag those images into slots in the Appicon Set.
Why is this happening? Thank you!
960x670 image is not allowed to set AppIcon, you can read doc following
https://developer.apple.com/library/ios/recipes/xcode_help-image_catalog-1.0/chapters/AddingLaunchImagestoanAssetCatalog.html
You need to have images of those separate specified sizes, and then you need to drag them into the place that is alotted for each size. You can either resize the icon manually or download software from the Mac app store to do it for you.
I have been reading through all the answers, but still can't figure out to what I'm doing wrong. I went to Project -> General -> Launch Image Source and set that field to LaunchImage, which is in my Assets.xcassets. I have left Launch Screen File field empty. I read at several places to delete LaunchScreen.xib file, but I don't have that in my Xcode project. I also have the right sizes of images that are required by apple for Launch Images. What should I do?
Select Project and go tab General. Make sure you have set image folder and remove lauchscreen.xib
Select arrow and go to folder. make sure you check:
Maybe it will help you.
But I strongly recommend you: use lauchscreen.xib or .storyboard. It is more better than using lauchImage. If you use lauchingScreen, you should use like this::
Drag image to xib , and set image to this imageview check option use as lauch screen on right side of xib file. It will work like a charm :)
Try adding the launchscreen image as the background image of you launchscreen.storyboard
You might want to try adding the retina images to your app. For me this did the trick. No launch image was shown on my simulator before adding them.
Please remember that you need portrait and landscape if your app does both.
LI retina 5.5 is size 1242x2208 retina 4.7 is 750x1334 (portrait) and opposite for landscape is true ie. retina 5.5 2208x1242 4.7 1334x750
Retina launch images are needed for ios 8/9
I am a newbie in iOS. I want to set Launch Image in my app. And I'm using Asset Catalog. And I know I have to drag and drop the image to the boxes that shows up when I'm using Asset Catalog. But a weird thing which is happening at that time is when I'm trying to drag-drop, it just comes back . As if Xcode is telling me NO PLACE HERE. Xcode doesn't let me set my Launch Images. I'm not able to DROP my images in those boxes. And I know the sizes of my images are quite correct. 640*960, 640*1136, 750*1334, 1242*2208.(And I don't want to use LaunchScreen because it only supports iOS 8 and later.)
It's even more weird that people are down voting without even telling the reason. (If you are not good enough to help at least don't discourage newbies)
Got the solution.
Just answering my question so that if anyone is having same problem then here is the solution. My problem was because by mistake I was using images of "jpg" format where in fact I should have used "png" . Now I'm using "png" and it works perfect.
Click on images.xcassets. You should see app icon in the list. At the bottom of that column there is a plus and minus button. Click the plus button.
Click on new Launch Image in the list. This covers iPad's and iPhone's from iOS 5-8 and covers portrait and landscape.
Launch screen can also be support for ios 8,
What you need to do set the Go to project->Media.xcassets on right side information tab you need to select iOS 7.0 and later sizes.
Then you set your launch screen inside the Launch images.
It will work definitely.
By apple provide the document Adding an iOS App Icon Set or Launch Image Set
Thanks
open Images.xcassets of your project
Drag file one by one on boxes as per its size.
See following image.
After doing all Remove LaunchScreen.xib file from your project
And remove Launch screen interface file base name from your plist file.
How do I set the images so that I can archive and validate my app? The screen looks like this now:
So the first one says 29pt, but then it also says 2x. So do I put a 29x29 image or a 58x58 image? And where do I put all of the other ones? (I know that there are more sizes than 29, 40, and 60).
Anyway, what I tried was I dragged a 29x29 png onto the first slot, a 40x40 onto the second, and a 60x60 onto the third and fourth. When I went to Product->Archive, I get
/Users/kendon/Documents/iPhone Apps/Sales Tool/Sales Tool/Images.xcassets: The app icon set named "AppIcon" did not have any applicable content.
I recently found this App called Icon Set Creator in the App Store which is free, without ads, updated on new changes, straight forward and works just fine for every possible icon size in OSX, iOS and WatchOS:
In Icon Set Creator:
Drag your image into the view
Choose your target platform
Export the Icon Set folder
In XCode:
Navigate to the Assets.xcassets Folder
Delete the pre existing AppIcon
Right click -> Import your created Icon-Set as AppIcon and you're done
Update: Unless you love resizing icons one by one, check out Schmoudi's answer. It's just a lot easier.
Icon sizes
Above image from Designing for iOS 9. They are the same for iOS 10.
How to Set the App Icon
Click Assets.xcassets in the Project navigator and then choose AppIcon.
This will give you an empty app icon set.
Now just drag the right sized image (in .png format) from Finder onto every blank in the app set. The app icon should be all set up now.
How to create the right sized images
The image at the very top tells the pixels sizes for for each point size that is required in iOS 9. However, even if I don't get this answer updated for future versions of iOS, you can still figure out the correct pixel sizes using the method below.
Look at how many points (pt) each blank on the empty image set is. If the image is 1x then the pixels are the same as the points. For 2x double the points and 3x triple the points. So, for example, in the first blank above (29pt 2x) you would need a 58x58 pixel image.
You can start with a 1024x1024 pixel image and then downsize it to the correct sizes. You can do it yourself or there are also websites and scripts for getting the right sizes. Do a search for "ios app icon generator" or something similar.
I don't think the names matter as long as you get the dimensions right, but the general naming convention is as follows:
Icon-29.png // 29x29 pixels
Icon-29#2x.png // 58x58 pixels
Icon-29#3x.png // 87x87 pixels
Launch Image
Although you can use an image for the launch screen, consider using a launch screen storyboard file. This will conveniently resize for every size and orientation. Check out this SO answer or the following documentation for help with this.
Useful documentation
App Icon
Launch Screen
The Xcode images in this post were created with Xcode 7.
To save a bit time:
1) You can mark your app icon images all in finder and drag them into your Assets catalog all at once by dragging into one of the empty slots of the app icon imageset. When you hold your drag over the slot, several of the other slots look selected and when you drop those all will be filled up at once. Note that this works in XCode 8 (I haven't tried XCode 7), but in XCode 9 beta not yet.
2) The "Technical Q&A QA1686" apple documentation site has the sizes per app icon slot already calculated for you in a nice image and also contains the correct image names conventions.
I've tried most of the above and a few others and have found https://appicon.co to be the easiest, fastest, and provides the most comprehensive set.
Drag your image onto the screen
Click Generate
Open the file just downloaded to your Downloads folder
Here, you may be able to drag this entire folder into Xcode. If not:
Double-click the Assets.xcassets folder
Select all files
Drag them to Assets.xcassets
Rename it to AppIcon
The correct sizes are as following:
1)58x58
2)80x80
3)120x120
4)180x180
I use a tool called Prepo to produce all the right image sizes. You simply feed the app you image file and it will spit out each necessary file with an appropriate name.
Once you do this, you can then drag in the appropriate files or simply point to your Prepo exported folder.
Now a days is really easy to set app-icon, just go to
https://makeappicon.com/ add your image, they will send you all size of App-icon (Also for watch & itunes as well), now Click Assets.xcassets in the Project navigator and then choose AppIcon. Now you just have to drag n drop the icon as required.
I found App called Iconizer. You can find repository on github. Iconizer can generate app icons for OS X, iPad, iPhone, CarPlay and Apple Watch with just one image.
Simply Drag and Drop your icon onto Iconizer, select the platforms you need and whether or not you want all platforms generated into one asset catalog, then hit export.
After that just replace (delete and import) your AppIcon in the Assets.xcassets
In the left list, right click on "AppIcon" and click on "Open in finder"
A folder with name "AppIcon.appiconset" will open.
Paste all the graphics with required resolution there.
Once done, all those images will be visible in this same screen(one in your screen shot). then drag them to appropriate box.
App icons have been added.
Same process for Launch images.
Launch images through this process are added for iOS 7 and below.
For iOS 8 separate LaunchScreen.xib file is made by default.
I quite like this app made by Jordi Bruin called Bakery
It allows emoji and SFSymbols for quick prototyping (not for the App Store in this case!)
It is as easy as drag and drop your design to the app and then again drag and drop to the asset catalog without having to fill in all the sizes by hand.
This is a very frustrating part of XCode. Like many, I wasted hours on this when I switched to a newer version of xcode (version 8). The solution for me was to open the properties for my project and under the "App Icons and Launch Images" choose the "migrate" option for the icons. This made absolutely no sense to me as I already had all my icons there, but it worked! Unfortunately I now seem to have two copies of my launcher icons in the project though.
As per updated version(Xcode 8.3.3) I saw that below resolution are required for all fields of AppIcon sets.
40x40
58x58
60x60
80x80
87x87
120x120
180x180
It comes with hdpi, xhdpi, xxhdpi etc.
Hope it will helps others.
Edited to 120x120
You can easily do it without resizing yourself or doing anything, just choose your icon at an app store icon generator website
https://getappscreenshots.com/app-icon-generator and it'll generate all required files and all icon sizes so you can just copy the files and paste in your project's folder!
You can get away with just adding a single image of size 1024*1024px.
Just add the image in like so
and select single size in the menu to the right.
Every thing is going fine. Just one issue with Launch Images in iOS7 with XCode 5 by using Asset Catalogue.
In my iPad App, i have splash images of all the sizes.
When i am selecting Portrait Non-Retina [768x1024], its added successfully; after that when i select Portrait Retina [1536x2048], then Non-Retina [768x1024] image removed and giving this error "No image with correct dimensions found". Vise Versa is also applying.
Same behavior is for Landscape Retina and Non-Retina images.
Please suggest any solution. Thanks in Advance.
Delete the image from the asset catalogue and copy it back again. Perform and Clean and then build. It should work.
I have investigated, how we can use Asset Catalog; Now it seems to be easy for me. I want to show you steps to add icons and splash in asset catalog.
Note: No need to make any entry in info.plist file :) And no any other configuration.
In below image, at right side, you will see highlighted area, where you can mention which icons you need. In case of mine, i have selected first four checkboxes; As its for my app requirements. You can select choices according to your requirements.
Now, see below image. As you will select any App icon then you will see its detail at right side selected area. It will help you to upload correct resolution icon.
If Correct resolution image will not be added then following warning will come. Just upload the image with correct resolution.
After uploading all required dimensions, you shouldn't get any warning.
You need to actually use asset catalog by clicking the asset catalog button. Then you will get templates specifying every size you need, and you can drag and drop or import you PNGs and see where you're missing images or the size is wrong. In asset catalog, clicking on the properties pane for an image will show you the size of the image it expects, and teh size you gave it, so you can easily see any discrepancies.
