If I develop my app with an SDK(binary) that other person developped and then the SDK certificate has expired,Can I submit my app to app store? Or should I get a new SDK with updating certificate?
SDK certificate
Can I submit my app to app store?
Yes. The code you submit to the App Store must be signed by you — this reflects the fact that you are ultimately responsible for its behaviour — so the expiration date on the original certificate is irrelevant.
Note that the App Store re-signs your code again as part of its distribution process. I talk about this in some detail in TN3161 Inside Code Signing: Certificates.
