Create a C array of retained pointers under ARC (Obj-C)

ky_create_c_array_of_retained_pointers_under_arc.m

// Note calloc() to get zero-filled memory.
__strong SomeClass **dynamicArray = (__strong SomeClass **)calloc(sizeof(SomeClass *), entries);
for (int i = 0; i < entries; ++i)
  dynamicArray[i] = [[SomeClass alloc] init];
 
// When you're done, set each entry to nil to tell ARC to release the object.
for (int i = 0; i < entries; ++i)
  dynamicArray[i] = nil;
 
free(dynamicArray);
 
 
/*
There are a number of aspects to note:
 
You will need to write __strong SomeClass ** in some cases, because the default is __autoreleasing SomeClass **.
The allocated memory must be zero-filled.
You must set each element to nil before freeing the array (memset or bzero will not work).
You should avoid memcpy or realloc.
