Hi,
In some calls to Cocoa API subroutines we do:

UIView *myView = [[UIView alloc] init];
[window addSubView:myView];
[myView release];

but sometimes you cannot release the temporarily allocated object, e.g. :


UIDatePicler *picker;

... (picker was initialised somewhere)


NSDate *date = [[NSDate alloc] init];
[picker setDate:date];
[date release]; // Opps! immediate release of 'date' causes program crash.


So is there a rule of thumb, like when should we release immediately after
passing the object to some Cocoa API calls?

Thanks.

Regards,
DairyKnight
