Question

I try to add object to my NSMutable array in my method, but keep getting error. It works, if I add the object in init. It doesn’t say that anything is wrong until I try to execute the code.

This is below the #import stuff where I declare two arrays:

NSMutableArray *actions1, *actions2;

This is in init:

actions1 = [NSMutableArray array];

Here I try to add 1 to the array:

- (void) storeAction:(int) action {
[actions1 addObject:@"1"];
}

The same code works in int as I said earlier.

I also would like it to store the int value declared “action”, but this didn’t seem to work either.

[addObject:@"%d", action];

[NSMutableArray array]; is returning an autoreleased object, by the time you try to access it, it is most likely deallocated already. Try [[NSMutableArray alloc] init]; instead. And than you should urgently check the memory management rules.
