(Objective-C) Create MIME Containing Plain-Text

Calls SetBodyFromPlainText to load plain-text into the MIME body. Also sets the Content-Type header to "text/plain", and the Content-Transfer-Encoding to an appropriate transfer encoding based on the characters found in the text.

CkoMime *mime = [[CkoMime alloc] init];

// Add a few header fields:
BOOL success = [mime AddHeaderField: @"Description" value: @"this is a test"];
success = [mime AddHeaderField: @"MyId" value: @"123"];

NSString *textBody = @"This is the plain-text body";

success = [mime SetBodyFromPlainText: textBody];

NSLog(@"%@",[mime GetMime]);

// The MIME should look like this:

// Description: this is a test
// MyId: 123
// Content-Type: text/plain; 
// Content-Transfer-Encoding: 7bit
// 
// This is the plain-text body

// Note: The Content-Transfer-Encoding may be changed.
// For example, to use "base64", do this:
mime.Encoding = @"base64";

// Show the MIME again, this time using the base64 
// transfer encoding:
NSLog(@"%@",[mime GetMime]);

// It should look like this:

// Description: this is a test
// MyId: 123
// Content-Type: text/plain
// Content-Transfer-Encoding: base64
