I have put all my icons and launch images under a folder called “Resources“, and I have added all the files into XCode.
When I select the launch images in the XCode by select the file under this folder, it said..
a file with name "Default.png" already exists. Do you want to replace it?
When I selected yes, and the file “Default.png” is being duplicated and place in the project root folder, so now I have two “Default.png“
Is it possible to use the file that already in the Resources folder?
iPhone-only applications:
Note: If your app is not running on an iPhone 4, and you provided both Default.png and Default@2x.png, iOS will automatically pick up Default.png as the launch image.
Solution : remove one Default.png place in the project root folder for launch Image
For ICON: Refer this link
