Objective-C
#import <CkoEmail.h>

// The AddHeaderField can be called to add any header field.
// If the header field already exists, AddHeaderField replaces it.
CkoEmail *email = [[CkoEmail alloc] init];
[email AddHeaderField: @"X-Priority" fieldValue: @"3 (Normal)"];

[email AddHeaderField: @"X-Priority" fieldValue: @"1 (High)"];

[email AddHeaderField: @"X-Priority" fieldValue: @"5 (Low)"];

// The X-Priority value ranges from 1 to 5, with 1 being 
// high priority, 3 is normal, and 5 is low.
// You may set X-Priority to the number alone:

[email AddHeaderField: @"X-Priority" fieldValue: @"1"];

// Including extra text, such as (High), should not 
// affect how the header is interpreted.
[email AddHeaderField: @"X-Priority" fieldValue: @"1 (High)"];
