Ios NSData AES触发器无法识别的选择器发送到实例错误

我的代码如下：

-七叶皂苷-

//错误

为什么会发生这种错误

--添加到NSMutableString

谢谢你的支持

我确实再次尝试了同样的答案，但我的代码仍然会触发相同的错误

再次帮助NSMutableString plz。

删除类别文件并再次添加它们检查目标。

您正在AESLib.m中进行导入吗？自从几年前我发布代码以来，我就没有碰过它。我会尽量抽出一些时间用最新的工具来测试它。

-(NSData *) encodeAES:(NSData *) argSource
{
    NSString APIV1_AES_KEY = @"//AAAAAAAAAAAAAAAAAAAAAA"; // 24 char
    NSString APIV1_AES_IV = @"//BBBBBBBBBBBBBB";  // 16 char
    NSData *key = [NSData dataWithBytes:APIV1_AES_KEY.UTF8String length:strlen(APIV1_AES_KEY.UTF8String)];
    NSData *iv = [NSData dataWithBytes:APIV1_AES_IV.UTF8String length:strlen(APIV1_AES_IV.UTF8String)];

    NSData *encData;
    @try {
        encData = [argSource encrypt:key withInitial:iv andPadding:kCCOptionPKCS7Padding];
        // Error Here
        return encData;
    }
    @catch (NSException *exception) {
        NSLog(@"Exception : %@", [exception reason]);
    }

    return nil;
}
