Example text

As a program executes it allocates objects in memory that it needs to continue. Periodically another process runs that looks for objects that are no longer reachable, meaning they have no references left to them in any code that is executing. This type of system works very well; though contrary to popular belief your code can still leak memory by creating objects and keeping a reference to them but never using them again. This system also has a bit of overhead associated with it. The system needs to continue executing the program being used while running the garbage collection process in parallel.

Its conceivable that the memory is still there and your code would execute just fine even though the memory has been marked for reuse. Listing 2-22 demonstrates how a zombie object could occur. secondInt = 5; int sum = [simpleClass sum]; } warning The NSObject class has a property called retainCount. You should never trust this value nor should you ever use it. It may be tempting to look at this value to try and determine when an object will be released or to find a memory leak. You should instead use the debugging instruments included in Xcode, in this case the Leaks instrument.

A solid threading model with proper locks also creates the same guarantee, so the use of atomic properties is limited. Most often you declare your properties as nonatomic to avoid the extra overhead. indd 31 31-01-2014 17:20:27 32 ❘ CHAPTER 2 Introduction to Objective-C The other attribute, strong and weak, are much more important to understand. As you learned earlier in this chapter, an object that has a retain count of zero will be deallocated. The concept of strong and weak with properties is similar.
