[iOS] Base64 編碼解碼 (Base64 Encoding Decoding)
先前已經研究果Base64編碼的原理，現在以iOS來實作看看⋯⋯
/**
Theme: Base64 Encoding Decoding
IDE: Xcode 7
Language: Objective C
Date: 104/10/16
Author: HappyMan
Blog: https://cg2010studio.wordpress.com/
*/
NSString *plainString = @"HappyMan";
// Encoding
NSData *plainData = [plainString dataUsingEncoding:NSUTF8StringEncoding];
NSString *base64String = [plainData base64EncodedStringWithOptions:0];
NSLog(@"%@", base64String); // SGFwcHlNYW4=
// Decoding
NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:base64String options:0];
NSString *decodedString = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding];
NSLog(@"%@", decodedString); // HappyMan
原來這麼簡單ＸＤ～
