Getting Finished Running <myapp> on phone, but no app launches

Question

Using an iPhone 4 running ios6.1, and xcode 4.6.3, with valid provisioning profiles, the app will not launch. The status bar just says it finished. I have tried: It works in the simulator fine. The app is a Utility Application. Rebooting (Everything) Product -> Clean Create new project, and move the code there.

The things is, I created a new project and just slapped a button on it, and it worked fine.

Found something new: I created a blank Utility Application and tried to run that on the phone, it did the same thing. Then I created a new blank application and tried to run it on the phone, it worked

Answer 1

If you are seeing and empty black screen in the simulator than you should check your rootViewController.

Possibly you are using a navigation controller and the rootViewController is not set. So the app is not aware that it should go to a specific view controller that you want to.

Answer 2

Do you have other device without JB? I've told sometimes JB can do unpredictable things to you device, not launching app seems like it.

Answer 3

Awful number of times this happens with my Xcode4.6 and I resolved most of the times with below few checks.

• Do a quick check if your not compiling any static library by mistake.
• Reset and relaunch the simulator/Power off your device & restart.
• Still if this continues - Quit and relaunch the Xcode.

Answer 4

Happens most of the times if you already have an app on the device/simulator installed with the same app id (bundle id)
