Question

Congratulations! You have mastered one of the most important parts of developing apps for the iPhone: Navigation using tables. In addition, you saw how to integrate tables with data stored in Core Data. Like so many other aspects of iOS development, it is crucial to know which methods to override to make the built-in functionality work to do what you want it to do. Change the cell layout to use the other two styles. Expand the settings screen to allow for specifying two sort fields. Then have the sorti be done by first one and then the other field. Choose different fields from the Contact class to display in the table. Change the display in the table to be on this form: Main label: Superman from Metropolis. Detail Label: Born on: April 18, 1938. Find a way to have the picker for the sort field display the fields with uppercase won and the name as Contact Name, rather than contactName.
