Answer 2

It looks like you may not have terminated an array declaration with nil. Without the nil you may have some memory weirdness as the runtime won't know where the array ends and the next bit of memory starts.

Answer 3

In Xcode if you are coding in objective-c and you are using some methods which take variable parameter list, you need to add nil object at the end of the list.

For example:

N**SArray names = [NSArray arrayWithObjects: @"Name1", @"Name2"];* //will result in the warning mentioned above

However, NSArray *names = [NSArray arrayWithObjects: @"Name1", @"Name2", nil]; //Correct

Hope this will help!
