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]);
