Here is an explanation of when and why to use @autoreleasepool in Objective-C:
Using @autoreleasepool in Objective-C
In Objective-C, objects are typically allocated on the heap and must be manually managed to avoid memory leaks. The @autoreleasepool construct helps manage the lifecycle of objects that are added to the autorelease pool.
When to Use @autoreleasepool
You should use @autoreleasepool in the following conditions:
1. Long-running loops
If you have a long-running loop that creates many temporary objects, wrapping the loop in an @autoreleasepool block can help reduce memory usage by releasing objects as the loop progresses, rather than waiting for the loop to complete.
2. Recursive methods
Recursive methods can quickly consume a lot of memory if they create temporary objects on each call. Using @autoreleasepool can help manage the memory usage.
