iOS开发 调用程序内部代码

//程序正常调用
EESigning *signer =  [EESigning signerWithCertificate:p12Provision privateKey:@"1"];



//越狱调用+
EESigning *signer =  [NSClassFromString(@"EESigning") signerWithCertificate:p12Provision privateKey:@"1"];


//越狱调用-
EESigning *signer =  [[NSClassFromString(@"EESigning") init] signerWithCertificate:p12Provision privateKey:@"1"];
