Universal iPhone/iPad Apps

In this talk, I covered how to create a universal iPad/iPhone applications. Most of the extra work in creating a universal application is due to the iPad and iPhone running different versions of iPhone OS. I covered how to gracefully support both versions of iPhone OS using various techniques as described in the iPad Programming Guide.

I showed an example application that shows a view controller as a modal on the iPhone or a popover on the iPad. You can download the example project's code from my GitHub.

4. I write software (and music)
5. What I made
7. 5.6MM+ unique users
8. So, universal apps
11. Let’s get along
12. But...
13. Dang you Apple
14. 3.2 3.1.3
15. So what does this mean?
16. Lots of annoying extra stuff
17. Have no fear, it’s not hard just annoying
18. The future is bright and far away
19. Let’s get started
20. The project
24. Conditional classes
25. UIPopoverController *popover = [[UIPopoverController alloc] initWithContentViewController:someViewController]; [popover presentPopoverFromRect:[sender frame] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; 1 2 3
26. Class popoverClass = NSClassFromString(@"UIPopoverController"); if (popoverClass) { UIPopoverController *popover = [[popoverClass alloc] initWithContentViewController:someViewController]; [popover presentPopoverFromRect:[sender frame] inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES]; } 1 2 3 4 5
27. User interface idiom
28. if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { // Do iPad stuff } else { // Do iPhone stuff } 1 2 3 4 5
29. Responds to selector
30. if ([self respondsToSelector:@selector(setContentSizeForViewInPopover:)]) { self.contentSizeForViewInPopover = CGSizeMake(320.0, 300.0); } 1 2 3
31. Demo
32. More work Don’t worry, it’s way easy
