The Definitive Guide to Injecting Dylibs into IPA Files: Modification, Tweaking, and Sideloading
Q: Can I inject multiple dylibs into an IPA? A: Yes, it is possible to inject multiple dylibs into an IPA, but this can increase the risk of stability issues or conflicts between the injected dylibs.
Several projects automate the entire injection process: Inject Dylib Into Ipa
Now use optool to add the LC_LOAD_DYLIB command to the app's main executable:
Tap on the imported app, select "Signature" from the available options, then tap "More Settings". The Definitive Guide to Injecting Dylibs into IPA
Modifying the binary breaks the original digital signature. iOS security will block the app from launching unless it is cleanly re-signed. cd extracted_app zip -r ../modded_app.ipa Payload/ Use code with caution. Re-sign the IPA:
Key concepts
Using a terminal on macOS is the most reliable way to inject dylibs manually. 1. Install insert_dylib
Once injection is complete, recompress the modified app back into an IPA: Modifying the binary breaks the original digital signature
