Are you sure your tempArray is properly initialized and is in fact a NSMutableArray (NSArrays are immutable and don't support addObject:/removeAllObjects/etc)?

Hm. Try adding a [tempArray count] check before the removeAllObjects in both functions.

The problem is with your tempArray object (retains & releases). Is tempArray a property ? How did you declared it ?

did you initialize tempArray before you removeAllObjects method? check this is null or not.
