Decode from Binary Encoding and Append String

Demonstrates how to decode from a binary encoding (base64, hex, url, etc.) and then append the decoded string to a Chilkat StringBuilder object.

Note: This example uses the new DecodeAndAppend method added in Chilkat v9.5.0.87.

Objective-C

#import <NSString.h>
#import <CkoStringBuilder.h>

BOOL success = NO;

//  We have the string "MÆRSK" in two forms:

//  This is the URL encoding of the windows-1252 representation.
NSString *nameWindows1252UrlEncoded = @"M%C6RSK";

//  This is the URL encoding of the utf-8 representation.
NSString *nameUtf8UrlEncoded = @"M%C3%86RSK";

//  Note that the result of loading a string into a string object 
//  is the same if we correctly specify the underlying charset encoding.
//  In the above example, we have the same string, but in different charset encodings
//  subsequently URL encoded.
CkoStringBuilder *sb1 = [[CkoStringBuilder alloc] init];
success = [sb1 DecodeAndAppend: nameWindows1252UrlEncoded encoding: @"url" charset: @"windows-1252"];

CkoStringBuilder *sb2 = [[CkoStringBuilder alloc] init];
success = [sb2 DecodeAndAppend: nameUtf8UrlEncoded encoding: @"url" charset: @"utf-8"];

//  sb1 and sb2 both hold the same string.
BOOL bEqual = [sb1 ContentsEqualSb: sb2 caseSensitive: YES];
NSLog(@"%@%d",@"bEqual = ",bEqual);

//  We can see the string is "MÆRSK" in both cases.
NSLog(@"%@",[sb1 GetAsString]);
NSLog(@"%@",[sb2 GetAsString]);
