Question

Say you have class Block

Class Block : NSObject

Now, you want to create array in C-style

Block *blocks[5]; // or calling malloc()
Block *aBlock = [[Block alloc] init];
blocks[0] = aBlock; 
// at this point, aBlock will be hand over to array blocks slot.
// not like NSArray, object of 'Block' will not retain by @property(retain)
// or should I call retain before hand over the value into its array and release afterward?
// should I still call below code to release object ?
// [aBlock release];

Can someone explain to me should I still need to release the aBlock object afterward?

Answer 1

No because the primitive array won’t be retaining each Block object. So if you release it, all Block objects will be cleaned up the moment the function exits scope
