16. iOS

17. Für iOS entwickeln Web-Apps „verpackte“ Web-Apps (PhoneGap) „Crossplatform-Tool-Apps“ (Titanium Mobile) „crosscompiled Apps“ (XMLVM) „native Apps“ (iOS SDK)

18. iOS SDK

19. iOS SDK Objective-C Cocoa Touch UIKit, MapKit, Event Kit UI, Game Kit, iAd, ... Media Core Graphics, Core Animation, Core Text, Open GL ES, Core Audio, AV Foundation, ... Core Services Core Foundation, Foundation, CFNetwork, Core Data, Core Location, Event Kit, ... C Core OS

20. Objective-C = C + Smalltalk ObjC C

21. Eigenschaften von Objectiv-C objektorientiert basiert auf Message Passing Dynamic Binding / Dynamic Typing Introspection Einfach-Vererbung und Protocols Erweiterungen durch Categories Properties (ab 2.0)

22. iOS und Memory Management Objective-C 2.0 bietet Garbage Collection. Aber leider nicht für iOS.  

23. Memory Management ohne GarbageCollection? Durch Reference Counting:

24. Die gute Nachricht: Ab iOS 5 gibt‘s AutomaticReference Counting. 

25. #import <Foundation/Foundation.h> @interfaceNewsItem : NSObject { NSString* title; NSString* subtitle; BOOL unread; } @property (copy) NSString* title; @property (copy) NSString* subtitle; @property (assign) BOOL unread; - (id)initWithTitle:(NSString*)aTitle andSubtitle:(NSString*)aSubtitle; @end NewsItem.h

26. #import "NewsItem.h" @implementationNewsItem @synthesizetitle, subtitle, unread; - (id)initWithTitle:(NSString *)aTitle andSubtitle:(NSString *)aSubtitle{ self = [super init]; if (self) { title = [aTitle copy]; subtitle = [aSubtitle copy]; unread = YES; } return self; } ... NewsItem.m

27. ... - (void)dealloc { [title release]; [subtitle release]; [super dealloc]; } @end NewsItem.m (cont.)

28. NewsItem* i1 = [[NewsItemalloc] initWithTitle:@"News Item 1" andSubtitle:@"Subtitle 1"]; NewsItem* i2 = [[NewsItemalloc] initWithTitle:@"News Item 2" andSubtitle:@"Subtitle 2"]; NSMutableArray* items = [[NSMutableArrayalloc] initWithObjects: i1, i2, nil]; News Items benutzen
