问题
I developed an app and created a .Ipa file and sync it with my iPad1 but the problem is, I am trying to sync the same app in to my other iPad2 using iTunes.
But it is not syncing and showing an error that the App can't be installed and installation failed!!!.
回答1:
There are several reasons for failed to instal in device.
1.check your provisioning profile contains device UDID of ipad2 added or not.
2.check your ipa file created properly or not.if you feel you created properly then delete the app from your first device which is having same app and instal the ipa again and check once.Then you come to know your ipa creation is correct.
3.one more reason might have take place is ipa may break accidentally.
回答2:
you can check these steps:-
Make sure that your iPad2 device ID is added to your provision profile you have created in developer portal.
Make sure that your bundle id in your plist is match with the your provisioning profile bundle ID you have choose to build your project.
Second thing you can check if the provision profile is installed on your device on not.
Thanks, Sandeep
