NSMutableArray *array = [NSMutableArray arrayWithObjects: @"one", @"two", @"three", @"four", nil];
NSArray *newAdditions = [NSArray arrayWithObjects: @"a", @"b", nil];
NSMutableIndexSet *indexes = [NSMutableIndexSet indexSetWithIndex:1];
[indexes addIndex:3];    
[array insertObjects:newAdditions atIndexes:indexes];
