![]() ![]() ![]() If you call malloc or any routine that allocates memory, you must balance that call with a corresponding free. The malloc library can only reclaim the memory you tell it to reclaim. However, apps that mix the use of Objective-C objects and C-based structures must manage the ownership of objects more directly to ensure that the objects are not leaked. For apps that use only Objective-C objects, the compiler’s ARC feature deallocates objects for you and generally avoids the problem of memory leaks. Leaked memory eventually forces the system to allocate additional virtual memory pages for the application, the allocation of which could have been avoided by reclaiming the leaked memory.įor apps that use malloc, memory leaks are bugs and should always be fixed. Leaks waste space by filling up pages of memory with inaccessible data and waste time due to extra paging activity. Memory leaks are blocks of allocated memory that the program no longer references. ![]()
