IOS Base64编码/解码

对一长串NSString数据进行Base64编码/解码，无非围绕着NSString与NSData之间进行转换。

Base64Util.h

#import <UIKit/UIKit.h>

/**
 * Base64工具类
 */
@interface Base64Util : NSObject

/**
 * Base64编码
 */
+(NSString *)base64Encode:(NSString *)data;

/**
 * Base64解码
 */
+(NSString *)base64Dencode:(NSString *)data;

@end

Base64Util.m

#import <Foundation/Foundation.h>
#import "Base64Util.h"

@implementation Base64Util

+ (NSString *)base64Encode:(NSString *)data{
    if (!data) {
        return nil;
    }
    NSData *sData = [data dataUsingEncoding:NSUTF8StringEncoding];
    NSData *base64Data = [sData base64EncodedDataWithOptions:0];
    NSString *baseString = [[NSString alloc]initWithData:base64Data encoding:NSUTF8StringEncoding];
    return baseString;
}

+ (NSString *)base64Dencode:(NSString *)data{
    if (!data) {
        return nil;
    }
    NSData *sData = [[NSData alloc]initWithBase64EncodedString:data options:NSDataBase64DecodingIgnoreUnknownCharacters];
    NSString *dataString = [[NSString alloc]initWithData:sData encoding:NSUTF8StringEncoding];
    return dataString;
}

@end
