Automatic Reference Counting

Guides | Tutorial By 4 years ago

Automatic Reference Counting (ARC) has been around since iOS 5, however it has been an optional tick box when beginning a new project, and if not selected, Manual Reference Counting (MRC) is used. As of Xcode 5, the ARC tick box is missing, and all new projects start with ARC. While you can still disable ARC manually in the project's config file, this is probably a good sign that ARC is the way to go for new projects.

Copy vs. Retain, Immutable vs Mutable

Guides | Tutorial By 5 years ago

In the Foundation framework for iOS and Mac the main container classes (NSString, NSArray, NSDictionary, and some others) have two states; Immutable and Mutable. If a class is immutable, it cannot be changed and is treated as ready only. When a class if mutable it can be modified after creation. It may seem that when passing one of these around it may be faster to retain it rather than copy it, because new memory does not need to be allocated. While this is true it can leave instabilities, see this example.

Xcode’s Analyzer (and how to prevent it)

Xcode’s “Analyzer” is normally a great way to determine where most memory leaks will occur in your project without actually running it. If you follow Apple’s Memory Management Guidelines the Analyzer is pretty accurate. By no means is it a replacement for the Profiler, but offers some quick checks.

Retain Loops and Delegates

Guides | Tutorial By 6 years ago

When using delegates in an object in Objective-C it is important that the delegate is only assigned within your object, and never retained. The reason for this is to prevent a retain loop, where two objects retain each other; they will never be released. The fix is simple, but can catch you off guard if you want to create an array or dictionary of delegates (using an NSDictionary or NSArray).
