App Rejection due to private API call

Today i got an app rejection from apple. The cause was the use of a private API. Does anyone know a tool which test for private API calls.

Heres a part of the message from apple:

...Using private APIs can lead to a poor user experience should these APIs change in the future. The non-public API that is included in your application is descriptionWithCalendarFormat:timeZone:locale:.

codesign failed with exit code 1

While building the distribution version of my iphone app i had to struggle with the codesign-tool:
"codesign failed with exit code 1"


Finally i fixed the problem:


The problem was that there where different names entered in the following configuration fields:


- Project -> Edit Active Target -> Properties Tab -> Field "Executable"

- Project -> Edit Active Target -> Build Tab -> Field  "Product Name"
- in info.plist (or *.plist) the field  "executable file"


So make sure that these fields contain the same value.


The root of the problem that I  renamed the executable file in the .plist file cause the initial name of the xcode project was not the name of the final product.
