Objective C Array and Object Release
- by david
Hi, I have a newbie question regarding when to release the elements of a NSArray. See following pseudo code:
NSMutalbeArray *2DArray = [[NSMutableArray alloc] initWithCapacity:10];
for (int i=0;i<10;i++) {
NSMutableArray *array = [[MSMutableArray alloc] initWithCapacity:5];
for (int j=0;j<5;j++) {
MyObject *obj = [[MyObject alloc] init];
[array addObject:obj];
[obj release];
}
[2DArray addObject:array];
[array release];
}
// use 2DArray to do something
[2DArray release]
My question here is, when I release 2DArray, do I need to explicitly release each of its element (array) first? Also, before I release the "array" object, do I need to release each of its element (MyObject) first?
I am new to Objective C. Please help. thanks.
