Scott Reed Brain Hz Software [email protected] (760) 845-3320

Things you need • An Intel based Mac – running 10.5 or 10.6 • iPhone SDK (3.0 or higher) • Mono for OSX • MonoTouch • MonoDevelop (2.2 RC)

How to get a Mac • Buy a Macintosh • Build a Hackintosh • Virtualize a Hackintosh

Buying a Macintosh • Already have a monitor? – Mac Mini (from $600-$800) • Desktop – iMac (from $1200 - $2000) • Laptop – MacBook ($1000) – MacBook Pro ($1200-$2500) •

Prices as of Deember 1st 2009 as stated on Apples website

Building a Hackintosh (HW) • From $300 - $2000 – but about half of what the equivalent Mac costs

• Intel based PC – Asus or Gigabyte motherboards most common

– http://www.insanelymac.com/foru m/index.php?showtopic=114834 • SATA AHCI supported hard drive

Building a Hackintosh (SW) • Darwin kernel Boot CD allows Mac OS X install – such as boot-132 from above link

• Bootloader (such as Chameleon) enables boot without CD • A good guide – http://lifehacker.com/5351485/ho w-to-build-a-hackintosh-withsnow-leopard-start-to-finish

Virtualize a Hackintosh • VMWare Workstation • Mac OSX Guest package instructions – http://www.insanelymac.com/forum/ index.php?showtopic=172474

iPhone SDK (History) • • • •

Originally announced March 2008 2.0 released July 2008 3.0 released June 2009 3.1.2 release October 2009

• $99 annual fee to deploy to AppStore

iPhone SDK (Content) • • • •

Core OS CoreServices Media CocoaTouch

• In Objective C (language) • Using XCode (the IDE) • and Interface Builder (?like Blend?)

Objective C • Combination of Smalltalk and C • Messaging syntax obj->method(parameter); // in C++ [obj method: parameter]; // in Objective C

• Named parameters -(returnType) method1: (paramType1)paramName1; -(returnType)method2WithParam:(paramType1)paramName1 andOtherParam:(paramType2)paramName2; [obj method2WithParam:p1 andOtherParam:p2];

• Header files and implementation files (.h and .m)

Other Objective C differences • Allows nil messaging • BOOL is YES and NO • Reference counting Person * person = [[Person alloc] init] [person release] – also a retain and dealloc

Mono Open Source .NET implementation Started July 2001 1.0 released June 2004 Current version 2.4.2, June 2009 Contains 2.0 and partial support for 3.0 (no WPF) • Also contains LINQ to Objects and XML • • • • •

MonoTouch • Wraps the iPhone CocoaTouch APIs with .NET • Current Version 1.2 • Free evaluation edition – Simulator only

• $399 personal edition – your phone or App Store

• $999 enterprise edition – phone, App Store, enterprise phones

MonoDevelop • IDE that targets .NET based languages • VisualStudio like • Supports refactoring, snippets, and intellisense

Caveats • Can’t simply port existing WinForms, WPF, or Silverlight apps over • Have to learn the iPhone way • All documentation for iPhone in Objective-C • MonoTouch documentation autogenerated at best
