  我希望它对你有所帮助

  NSString *decodeString = @"Raja";
  

  编码字符串

  NSData *encodeData = [decodeString dataUsingEncoding:NSUTF8StringEncoding];
  NSString *base64String = [encodeData base64EncodedStringWithOptions:0];
  NSLog(@"Encode String Value: %@", base64String);
  

  解码字符串

  NSData *decodedData = [[NSData alloc] initWithBase64EncodedString:base64String options:0];
  NSString *decodedString = [[NSString alloc] initWithData:decodedData encoding:NSUTF8StringEncoding];
  NSLog(@"Decode String Value: %@", decodedString);

  尝试使用这样的..首先你需要得到这个base64库

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

  然后导入此文件

  #import "NSData+Base64.h"
  
  NSData *data = [NSData dataFromBase64String:baseString];
  
  NSString *convertedString = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding];
  

  我希望它有所帮助 .
