Q: How to set the application icon that will be shown on the iPhone?
Ans: To set icon first one needs to create 57×57 image (type: png). You have a choice of apps that can do this your you so feel free to use any of them that you like (Photoshop, GIMP, Paint, etc). Once image has been created please add it into your Resources folder of your project. Next, one needs to edit Info.plist in your project (under Resources section of your project in Xcode). Find the Info.plist file and open it. It should display you a table with keys/values in the columns. Please change the Value for Key “Icon file” to be the same name as the name of your image file. And that is it. If you compile your application it should now show the icon on your iPhone (or your simulator).
