Append Part to MIME

See more MIME Examples

Demonstrates the AppendPart method for adding sub-parts to MIME. Objective-C

#import <CkoMime.h>

BOOL success = NO;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  Create a text/plain part.
CkoMime *ptMime = [[CkoMime alloc] init];
[ptMime SetBodyFromPlainText: @"This is the plain text body"];
NSLog(@"%@",[ptMime GetMime]);
NSLog(@"%@",@"****");

//  The ptMime contains:
//  ---------------------------------------
//  	Content-Type: text/plain
//  	Content-Transfer-Encoding: 7bit
//  
//  	This is the plain text body
//  ---------------------------------------

//  Start with an empty MIME object...
CkoMime *topLevelMime = [[CkoMime alloc] init];

//  Initialize it to a multipart Content-Type.  We'll use multipart/mixed.
[topLevelMime NewMultipartMixed];

//  Append the ptMime as a child.
[topLevelMime AppendPart: ptMime];
NSLog(@"%@",[topLevelMime GetMime]);
NSLog(@"%@",@"****");

//  The topLevelMime contains:
//  --------------------------
//  	Content-Type: multipart/mixed; boundary="------------010907090104040508040404"
//  
//  	--------------010907090104040508040404
//  	Content-Type: text/plain
//  	Content-Transfer-Encoding: 7bit
//  
//  	This is the plain text body
//  	--------------010907090104040508040404--
//  

//  IMPORTANT: A copy of the MIME passed in AppendPart is appended.
//  Therefore, in this case, changing ptMime does not change the text/plain sub-part in topLevelMime.
//  For example:
[ptMime SetBody: @"this is the new plain text body."];
//  topLevelMime is unchanged.
NSLog(@"%@",[topLevelMime GetMime]);
NSLog(@"%@",@"****");

//  To change the content in topLevelMime, we must get the text/plain part.
//  For example:

CkoMime *ptMime2 = [[CkoMime alloc] init];
[topLevelMime PartAt: [NSNumber numberWithInt: 0] subPart: ptMime2];

[ptMime2 SetBody: @"this is the new plain text body."];
//  Now topLevelMime is changed.
NSLog(@"%@",[topLevelMime GetMime]);
