Get MessageSet IDs as a Comma-Separated String

Demonstrates the Chilkat MessageSet.ToCommaSeparatedStr method, which returns the unique identifiers as a comma-separated string in ascending numeric order. It takes no arguments; an empty set returns an empty string. This example inserts a few ids and prints them.

Background: This is the fully expanded, human-readable form — every identifier listed explicitly, such as 1,2,3,5. It is handy for logging or display. When you need the terse form that collapses consecutive runs into ranges (for example 1:3,5), use ToCompactString instead. Like the compact form, the returned string contains only the numeric values and not the HasUids setting.

CkoMessageSet *msgSet = [[CkoMessageSet alloc] init];

//  Build a set by inserting individual identifiers.  The insertion order does not matter;
//  the identifiers are kept in ascending order and duplicates are ignored.
[msgSet InsertId: 3];
[msgSet InsertId: 1];
[msgSet InsertId: 2];
[msgSet InsertId: 5];

//  Get the identifiers as a comma-separated string.
NSString *csv = [msgSet ToCommaSeparatedStr];
NSLog(@"%@",csv);
//  Output: 1,2,3,5
