2 An Objective-C Primer

Declaring Objective-C Types Sending Messages Understanding Selectors Declaring Classes Using Protocols Adding Methods to a Class Using Informal Protocols Synthesizing Methods with Declared Properties Understanding self, _cmd, super Understanding the isa Pointer Initializing Classes Reading Type Encodings Using Blocks

3 Memory Management

Retaining and Releasing Assigning to Instance Variables Automatic Reference Counting Returning Objects via Pointer Arguments Avoiding Retain Cycles Migrating to ARC Autorelease Pools Using Autoreleased Constructors Autoreleasing Objects in Accessors Supporting Automatic Garbage Collection Interoperating with C Understanding Object Destruction Using Weak References Allocating Scanned Memory

Supporting Two-Stage Creation Copying Objects Archiving Objects Creating Designated Initalizers Enforcing the Singleton Pattern Delegation Providing Façades Creating Class Clusters Using Run Loops

5 Numbers

Storing Numbers in Collections Performing Decimal Arithmetic Converting Between Strings and Numbers Reading Numbers from Strings

6 Manipulating Strings

Creating Constant Strings Comparing Strings Processing a String One Character at a Time Converting String Encodings Trimming Strings Splitting Strings Copying Strings Creating Strings from Templates Matching Patterns in Strings Storing Rich Text

7 Working with Collections

Using Arrays Manipulating Indexes Storing Unordered Groups of Objects Creating a Dictionary Iterating Over a Collection Finding an Object in a Collection Subclassing Collections Storing Objects in C++ Collections
