NSArray becoming invalid after assignment

Thi开发者_StackOverflow中文版s is a strange problem, but two of my NSArrays are becoming invalid right after assignment. I went into debug and verified this during assignment. The screenshot shows it all. I must be missing a silly error somewhere - can someone please help!

Thank You!

You need to send the -retain message to the array on assignment, like this:

ivar = [[NSArray arrayWithObjects:@"a", @"b", @"c", nil] retain];

The reason why they are going out of scope is because -arrayWithObjects: returns an autoreleased object. It is for this reason that you must send it the -retain message.

Also, don't forget to -release these objects in your -dealloc method.

Use -retain- dude. This will solve your problem.
