iphone - iOS UI - how to tell user that there are no data in table view? -

-

this situation:

a user filters database selecting keywords list, presses "search". pushes instance of uitableviewcontroller subclass onto navigation stack.

in viewwillappear: method, data fetched core data , stored in ivar, ready table view's data source , delegate methods.

so far good.

the ui problem arises when there no results.

this simple architecture means empty result set yields empty table view no explanations.

it ui tell user "your search gave no results, please try fewer keywords".

my question this:

what best way provide relevant feedback user, without having change architecture much?

i thinking using table header, esteemed colleagues here think?

using table header not bad option. can go that. can try other options showing info in simple label or perhaps alert. wouldnt recommend alert.

-
i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines.
