Methods to flush the HTML5 Application Cache on iOS. In a UIWebView Webkit uses an sqlite database to store the resources associated to a cache manifest, as there is no API yet to flush the Application Cache you can use this method which delete entries directly from the database. However, this approach could break anytime if the implementation o…
static NSString *cacheDatabaseName = @"ApplicationCache.db";
static NSString *cacheGroupTable = @"CacheGroups";
static NSString *cacheGroupTableManifestURLColums = @"manifestURL";
static NSString *cacheTable = @"Caches";
static NSString *cacheTableCacheGroupId = @"cacheGroup";
/**
Clears the cached resources associated to a cache group.
@param manifestURLs An array of `NSString` containing the URLs of the cache manifests for which you want to clear the resources.

A category method for NSArray that facilitates enumeration with regular draining of the autorelease pool. Useful for those long, memory accumulating loops.

Ground Control additions, see description.md file below

Ground Control by @mattt is a great iOS library to remotely configure your iOS app by sending plists from a server to your app and then updating the user defaults values.

I wanted to extend this a bit with the following ideas in mind:

  • Define the values in a JSON file, instead of uploading an updated plist file to the server
  • Define values independently for given bundle identifiers, bundle version and language combination, so I can modify e.g. beta and debug versions independently from released apps
  • Values can be defined in a default language for a bundle version and overwritte on language specific entries like en. You can also only use default or only use specific languages
  • Return an empty plist for all unknown bundle identifiers or bundle versions
  • Don't check for config updates on every startup or every time the app becomes active, but only once a day or a remotely configurable amount of days
  • Right now the server side ph
