2.5 Memory Management

Here, we explain the concept of “object lifespans” and walk through managing memory in a Cocoa app. We’ll also introduce the Instruments application and the Clang Static Analyzer, which are two awesomely powerful debugging tools that ship with Xcode. Finally, we’ll hit some smaller topics such as typedefined primitive values like NSInteger and CGFloat that you’ll see commonly in Mac apps.
