The documentation for Cocoa's NSFetchRequest fetchLimit property says:
The fetch limit specifies the maximum number of objects that a request should return when executed.
If you set a fetch limit, the framework makes a best effort to improve efficiency, but does not guarantee it.
However, it doesn't tell you how to unlimit the maximum number of objects that a request should return if the fetch limit has already been set.
How can I return an unlimited number of matching objects after the previously limiting the number of objects with fetchLimit on my NSFetchRequest?
