Ios Memory Allocation

Memory partition:

1) stack: the stack zone is automatically allocated and released by the compiler, and stores the parameter values of functions and the values of local variables. The operation method is similar to the stack in the data structure.
2) heap-generally assigned and released by the programmer. If the programmer does not release the heap, it may be recycled by the OS at the end of the program. (In ios, alloc is stored in the heap)
3) Global (static)-the storage of global and static variables is placed in one area, and the initialized global and static variables are in one area, uninitialized global variables and uninitialized static variables are in another adjacent area. -The system is released after the program ends. Note: Global zones can be divided into uninitialized global zones:. bss segments and initialized global zones: data segments.
4). The constant zone-constant string is placed here. The program is released by the System
5). Code area-stores the binary code of the function body.
