Question

我使用CoreData从sqlite数据库中获取数据，并获得了NSString值：

"SxzYEWe6vE2ggLy5k9XV0Q24QJoOfvrHt9jCpq8CgCkGvfdgghjPIhDH0qZkNXjSHQJEw0cbGzFEoqZSIpImoqcuc8iA57oRne31fxgigPLWiAyAjjNnam68Z25hArGzDXudEA1AXoSM1TmlLMSV6c3XfDZM/IPPR245K5+DawOH5M8ZdUnbDyqVKRsi6KvqKou7mVA8DoZWrPBgN5YbvVC/da0F9QHCcq8Di8dNQ2/sf/oVs/A+ThHnglkscKyFuQ3FH+HNjENG2ZHtyWe1fQ=="

它似乎是一个base64编码的字符串。我尝试了很多方法来解码字符串：

NSData *dataString = [[NSData alloc] initWithBase64EncodedString:data.desc options:0];
NSString *textMeaning = [[NSString alloc] initWithData:dataString encoding:NSUTF8StringEncoding];
// textMeaning return (null).

以前有人看过这个编码过的字符串并知道如何解码吗？

尝试使用此base64方法进行解码，

NSString *decodeString = @"Apple";

    //Encode String

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


    //Decode String

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