I found this in a category in a (very) old project of mine. You could easily
speed it up by using arrays, but this version worked well enough for my needs.
- (NSIndexPath*) indexPathByAddingIndexPath:(NSIndexPath*) indexPath {
NSIndexPath* path = [self copy];
for (NSUInteger i = 0; i < indexPath.length ; i++) {
path = [path indexPathByAddingIndex:[indexPath indexAtPosition:i]];
}
return path;
}
- (NSIndexPath *)indexPathByAddingIndexInFront:(NSUInteger)index {
NSIndexPath* indexPath = [NSIndexPath indexPathWithIndex:index];
return [indexPath indexPathByAddingIndexPath:self];
}
Thanks,
Jon
