copy NSArray inside an empty NSArray
I have a first NSArray firstArray
and I do
[firstArray remo开发者_C百科veAllObjects];
after I want fill it with the content of an other array secondArray
is it right write in this way?
firstArray = secondArray;
No, firstArray = secondArray
will reassign the pointers, this is not the behavior you want. You want [firstArray addObjectsFromArray:secondArray]
Since the firstArray is an NSArray, you will want to do this instead:
firstArray = [NSArray arrayWithArray:secondArray];
