Ad-Hoc distribution - The application "<application name>" was not install on the iPhone "<iPhone name>" because the signer is not valid

what does it really mean when itunes complains that??

The application "" was not install on the iPhone "" because the signer is not valid.

we have got this error when we use "Build and Archive" or even with "Ad-hoc" distribution method with the targeted iPhone's UUID registered with Provisioning portal and generated new provisioning profile before we build the binaries...

then we will ship the binaries via email to our tester... they will try to ins开发者_如何学编程tall the application and this error always appear.

any idea what happened?

@Yit Ming:

There can be three issues:

1) It may be the case your provisioning profile either has expired.

2) It may be your app is not code signed with a proper provisioning profile.

3) It may be the case that your device ID may not be added to the provisioning profile.

Hope this helps

i have already found a solution to my problem.

as i mentioned previously, even if i use the method "Build and Archive" to compile a binary (in .IPA) to be installed in my tester's device, occasionally i will still get the error

The application "" was not install on the iPhone "" because the signer is not valid.

This is because the provisioning profile is not being installed properly to the device... (you can verify whether your provisioning profile is being installed by Settings -> General -> Profiles)

What i have done to resolve this issue is, i will copy my provisioning profile and .ipa file to my tester.

Then my tester will drag both of the files into his iTunes.

This will ensure that the provisioning profile is being installed to the device. then woalla!
