App dies on startup but not crash report

2019-03-26 16:55发布

I've given an ad hoc version of my app to some users. Two of them have the app die on start up while one user has no issues. I can also install the ad hoc without issue...but that is always the case for me. One user sent the info below from the Xcode Organizer Console. They didn't find any crash logs. I don't know what to make of the info below. The one thing that stands out is "Permission denied".

I place the provisioning and myapp.app files in a dropbox folder. The user then retrieves the files from the same location. I've run codesign against the .app file in the dropbox and get valid output:

codesign -vvvv myapp.app
myapp.app: valid on disk
myapp.app: satisfies its Designated Requirement

Any one have some ideas how I can figure out why the app doesn't work for this user?

Here is the Console output from one user. They couldn't find any associated crash logs:

Dropbox for me as well, zipped and it worked fine.

Ensure the executable has the same name in the updated version. I found if these don't match up, I get the exact same error messages as the asker. This is defined in the info.plist.

My team was trying to simulate the user upgrading an old version of our app to a new one. The new version was very different and we'd created a whole new project with new target and everything. Unfortunately this changed the executable name. Changing this back to the original made the upgrade work perfectly.

Try using the iPhone Configuration Utility, a free download from Apple. I had the same problem, uninstalled and installed using the iPCU and now it works perfectly.

It's somewhat unintuitive to use, try googling for provisioning profile iCPU. I found detailed instructions on a "redfin's developper blog".

The key word I think you have used is the word 'dropbox'. I've just spent the last 2 weeks trying to work out my app would not work on other machines and I have worked out that is because I have been distributing the app via DropBox with out zipping it.

Try putting the app in a zip file before uploading to DropBox. Instruct the users to download the zip file, unzip it and install the app.

My guess is that DropBox is stuffing up some of the files in the app package.

I've been fighting this for some time, and in my case it was a result of our build system using a different zip routine which did not respect OSX's resource forks. I don't know much about them, but in short they are an HFS construct for storing extra metadata about a file/dir which is hidden from most tools. Compressing with finder seems to work, as well as ditto. More info here: http://xahlee.org/UnixResource_dir/macosx.html

Yep, we had the same issue with DropBox... zip the file first.
