isEqualToArray: returning NO for equal arrays
isEqualToArray: returning NO for equal arrays

I've got two equal arrays that contain an array of dictionaries
containing two objects each (an NSDate and an NSString).
If I compare them with isEqualToArray:, they're marked as not equal.
However, if I iterate the arrays and compare the dictionaries with
isEqualToDictionary: none of them are considered to be unequal. I
don't get it.... Why is isEqualToArray: returning NO (the last 0
after the output of each array)?
NSLog(@"Stored Adobe Files (%@) versus actual adobe files (%@), %d",
storedFiles, newFiles, [newFiles isEqualToArray:storedFiles]);

On this iteration, mistmatch is never YES. They're always equal.
if (storedFiles and newFiles and [storedFiles count]==[newFiles
count] and ![newFiles isEqualToArray:storedFiles])
{
int i=0;
BOOL mismatch=NO;
for (i=0;i<[newFiles count];i++)
{
NSDictionary* storedDict=[storedFiles objectAtIndex:i];
NSDictionary* newDict=[newFiles objectAtIndex:i];
if (![storedDict isEqualToDictionary:newDict])
{
NSLog(@"%@ does not equal %@",
storedDict, newDict);
mismatch=YES;
break;
}
}
if (!mismatch)
equalArray=YES;
}
