When creating a custom iOS application using the Strategy Mobile SDK framework, it may be desireable or required to clear all or some device caches. There are preferences in the Mobile Server that allow you to delete caches when you perform certain actions like closing the app. However, to have more control when the caches should be deleted, you'll need to do it programmatically.
If using Strategy Mobile 9.3.0, follow KB44809 . However, this API is no longer available for the most recent release. With 9.4.1 Update 5, use the following code:
To delete all caches:
[[MSICacheManager manager] deleteAllCaches];
To delete the caches of one document/report only:
[[MSICacheManager manager] deleteCachesForObjectId: objectid projectInfo: pi];
To delete the caches that were created before a specific date:
[[MSICacheManager manager] deleteAllCachesBeforeDate:date];
A use case for this API would be to ensure that a prompted report does not save the prompt answers previously executed. With this code in place
