SUMMARY
In this chapter, you have seen how to port an existing iPhone application to support both the iPhone and the iPad. In general, the Universal application approach is the recommended one, as it enables you to maintain just one code base that can target multiple platforms.
EXERCISES
- What function enables you to determine the device platform on which your application is currently running?
- What are the different values available for the Targeted Device Family setting in your Xcode project?
Answers to the exercises can be found in Appendix D.
