I have an array of NSStrings that in some circumstances, I'd like to go
through using fast enumeration starting with the second element in the array.
After a bit of fooling around, I came up with the following, which seems to
work:
NSEnumerator *myEnumerator = [arrayOfLabels objectEnumerator];
NSString *aString = [myEnumerator nextObject]; // gets us past the
first element
NSLog(@"the label is %@", aString); // just to check;
doesn't get used
NSArray *arrayOfLabels = [myEnumerator allObjects];
for (aString in arrayOfLabels) {
// these are the strings that I'm interested in and will use
NSLog(@"the label from enumeration is %@", aString);
}
But I worry that in my inexperience with fast enumeration I may have committed
a sin that is likely to bite me later, or that what I've done is really less
effective than using an old-fashioned loop. Perhaps some of you have run
bench-marks or come up with a more elegant way of doing this sort of thing.
Many thanks for your insights,
Boyd
