objective-c - 这会造成任何泄漏吗？

Question

我在 mutableCopy 中有包含 Store 类型对象的数组。我释放数组，我释放数组之前释放所有对象吗？

NSMutableArray *stores=[[NSMutableArray alloc]init];
[stores addObject:[store1 mutableCopy]];
[stores addObject:[store2 mutableCopy]];
[stores addObject:[store3 mutableCopy]];
...
[stores release];

Answer 1

If you don't use ARC, then you need to release your objects at some point, since the - mutableCopy method creates a new object with a retain count of +1. To avoid leaks, you should write:

[stores addObject:[[store1 mutableCopy] autorelease];

Now, there is no reason not to use ARC. If you use ARC, you're fine and you don't call - release on anything.

Answer 2

是的。

你应该使用：

[stores addObject:[[store1 mutableCopy] autorelease]];
