Launch iOS app to launch

I am making an application that uses GCM, a background task and a keychain to save user information. I released the version using my development certification by adding the UDID of our device to the Apple developer account. But after a few days, I received feedback from users that a crash occurs every time they start. I am looking through the code but cannot find this error. I got these logs:

Please help me with this. Thank you all. I often revoke and create new certificates and profiling and use them for programming. This is normal?

I know you have a workaround, but I prefer to explain why this happens.

You need the right file for your project and enable APNS with development or distribution. Apple doc

 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>aps-environment</key> <string>development</string> </dic>

Your file may be similar to this, but it indicates distribution, so using development will cause it to fail.

Hope this helps

Although the stack is not very clear, it narrows your crash to a few things.

  • Your certificates do not look valid. Go to Keychain Access and check if you have a valid certificate and Keypair is attached to it.

  • Your Provisioning profile has become invalid. Go to developer.apple.com and verify that your security profile that you used is valid.

  • Permissions to use Facebook are revoked for any reason. Please check your Facebook app and make sure everything is in order.
