Automatic reference counting (ARC) was introduced in the iOS 5 sdk to free Objective-C programmers from having to handle memory management by making memory management the job of the compiler.
If you developer with Objective-C prior to the iOS 5 SDK or talked to Obj-C programmers then you are probably aware of how tedious task memory management could become. When using ARC there is no need for retain and release calls, and not only that in many cases ARC can provide a significant performance increase.
You can read many of the fine details about automatic reference counting in the official documents on the LLVM website here.
On this page you’ll find tutorials and guides giving a general overview of ARC and handling specific cases. If you’d like to submit an ARC related tutorial you can do so here.
Other iOS 5 SDK related tutorials can be found on the iOS 5 tutorial page.
