NSString * success = [NSString stringWithFormat:@"%@%@",BASE_URL,CALLBACKSUCCESS];

NSData* successOriginalData = [successdataUsingEncoding:NSUTF8StringEncoding];

NSString * successBase64String = [successOriginalData base64EncodedStringWithOptions:NSDataBase64Encoding64CharacterLineLength];

successBase64String = [successBase64StringstringByReplacingOccurrencesOfString:@"/"withString:@"_"];

successBase64String = [successBase64StringstringByReplacingOccurrencesOfString:@"+"withString:@"-"];

successBase64String = [successBase64StringstringByReplacingOccurrencesOfString:@"\n"withString:@""];

successBase64String = [successBase64StringstringByReplacingOccurrencesOfString:@"\r"withString:@""];

普通的base64

NSString * success = [CALLBACKSUCCESS stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLQueryAllowedCharacterSet]];
