unidbg iOS 如何补方法

把unidbg-iOS/test/resources/app 下的ipa包换成自己的ipa包。 同时,把IpaLoaderTest也改成自己的xxxx.ipa包。

public void testLoader() throws Exception {
    long start = System.[i]currentTimeMillis();
    File ipa = new File("unidbg-ios/src/test/resources/app/xxxx.ipa");
    if (!ipa.canRead()) {
        ipa = new File("src/test/resources/app/xxxx.ipa");
    }

运行IpaLoaderTest。会报错 +[NSProcessInfo instancesRespondToSelector:]: unrecognized selector sent to class。

报错如下: NSForwarding: warning: selector (0x10d9499c2) for message ‘instancesRespondToSelector:’ does not match selector known to Objective C runtime (0x10c97eba0)-- abort

看报错是某个方法没有实现导致的, 如果我需要补方法,如何实现呢?
