IPA installation file after xcode jailbreak is created

Under normal circumstances, it is a little troublesome to publish a test version to the user to ask the device ID of the other party and add it to the developer certificate. If it is a jailbroken machine, you can use xcode to create an IPA file, and directly synchronize it with iTunes, which is much more convenient.

1. Select iOS device as the running target.
2. Edit scheme-> Select Run [app name]-> select release in the build configuration drop-down box.
3. Generate the compilation file, product-> build
4. Create a payload directory anywhere
5. Go to the compilation directory, and find xcode> preferences> locations> derived data.
6. Find the release-iphoneos directory and copy [app name]. app to the payload directory created in step 1.
7. Compress the payload directory and change it to. IPA.
8. Double-click to add to iTunes
9. Connect the device and synchronize it.

This article uses the helloworld project as an example to teach you how to use the developer signature to package an IPA that can be installed on a jailbroken iOS device.

1. Create helloworld. app

1. Select the developer signature for build settings in the project.
   
2. Confirm that scheme selects the iOS device. If you connect to the device, remove it.
   
3. Click product> build.
   
4. After the build is complete, retrieve helloworld. App. You can find helloworld. app through the tree structure products on the left side of xcode,
   
5. Right-click show in finder.

Copy code

2 generate Hellworld. IPA

1. Create the payload folder, copy helloworld. app, and
   
2. Copy the itunesartwork file and itunesmetadata file to the same directory as the payload folder.
   
3. (Itunesartwork and itunesmetadata can be extracted from the IPA published to the appstore,
   
4. This ensures that the packaged IPA information is consistent with the application information published to the appstore .)
   
5. Select the itunesartwork, itunesmetadata, and payload folders, and right-click "compress 3 items"
   
6. Change the compressed file archive. Zip to helloworld. IPA.

Copy code

The generated helloworld. IPA can be installed on the jailbreaking device.
