NSString *base64String = [encodeData base64EncodedStringWithOptions:0];
NSLog(@"Encode String Value: %@", base64String);

Decode String

NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:base64String options:0];

Try to use like this..First you need to get this base64 library

尝试使用这样的..首先你需要得到这个base64库

https://github.com/l4u/NSData-Base64

And then import this file

然后导入此文件

   #import "NSData+Base64.h"

NSData *data = [NSData dataFromBase64String:baseString];

NSString *convertedString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];

I hope it helps.
