Objective-C

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

BOOL success = NO;

CkoJws *jws = [[CkoJws alloc] init];

//  Load the JWS compact serialization.
NSString *jwsCompact = @"eyJhbGciOiJIUzI1NiJ9.VGhpcyBpcyB0aGUgY29udGVudCB0byBzaWduLg.<signature>";
success = [jws LoadJws: jwsCompact];
if (success == NO) {
    NSLog(@"%@",jws.LastErrorText);
    return;
}

//  Get the JWS payload as text into a StringBuilder, decoded using the given charset.
CkoStringBuilder *sbPayload = [[CkoStringBuilder alloc] init];
success = [jws GetPayloadSb: @"utf-8" sbPayload: sbPayload];
if (success == NO) {
    NSLog(@"%@",jws.LastErrorText);
    return;
}

NSLog(@"%@",[sbPayload GetAsString]);
