Hi,
As I understand it, @property (retain) synthesizes something like this:
- (void)setMyProp:(NSString*)value
{
[value retain];
[_myProp release];
_myProp = value;
}
It is not however clear, and I haven't found it in the guide, whether
it's still my responsibility to call [_myProp release

There are varying opinions on how you go about it, but yes, you still
need to make sure _myProp is released in dealloc. I prefer

You can't customise the tab view that way (unless you subclass it and
do it yourself), but there's a much easier way.
Just set the tab view to tab

How are you determining which call fails? Is there a back trace?
Your code compiles and runs fine here (10.6).
It will help if you provide some additional details, e.g. version,
backtrace, some additional context around the failure.
