Join Todd Perkins for an in-depth discussion in this video Applying an app icon, part of Building a Note-Taking App for iOS 8.
- Now let's set an icon for our application.…In the navigator, I have my project selected.…So that's Plain Ol' Notes and in the center area,…I can see my Bundle Identifier, the Version…number, and other settings for my project.…If I scroll down, I can find the section…called App Icons and Launch Images.…Through here, after App Icon Source, I can…click the arrow button and see the icons for my application.…Note that you can also get here through the project…navigator by single clicking Images.xcassets.…
So in here, I'm going to make sure to select AppIcon…and then I see all of these dotted lines,…which are empty squares indicating…that I don't have any icons set yet.…Now, I'm going to hide the utilities…area to get a little bit more space here.…So what we need to do is drag the appropiate…size of icons onto these squares from Finder.…The way that we know what size the icons need to be is by…multiplying the point value by the numbers next to the x's.…
So you can think of the point value as sort…of the base size, or the 1x version.…
Each of these courses helps you build a complete mobile app from scratch; this installment uses the iOS SDK and Xcode to get the job done. Author Todd Perkins shows you how to create an Xcode project, lay out apps visually, connect UI elements to code, and save data to persistent storage. Start here with iOS 8, and compare your results with the Android and Windows Phone courses to learn about the differences and similarities of these mobile platforms.
