ios - How do i loop an nsobject once saved to -

i using nsmutablearray store items in list form web service. how read data out of array display random quote.

as trying avoid hitting webservice twice or on complicating it?

nsinteger randomint = arc4random_uniform(3); nsstring *baseurl = @"http://movie-quotes.herokuapp.com/api/v1/quotes"; nsstring *webserviceurl= [nsstring stringwithformat:@"%@/%ld", baseurl,(long)randomint]; randomquotes = nil;  dispatch_queue_t queue = dispatch_get_global_queue(dispatch_queue_priority_default, 0); dispatch_async(queue, ^{     // load json string our web serivce (in background thread)     nsdictionary * dictionary = [jsonhelper loadjsondatafromurl:webserviceurl];      dispatch_async(dispatch_get_main_queue(), ^{          randomquotes = [nsmutablearray array];          // iterate through array of quotes records in dictionary         (nsdictionary * onequote in dictionary)         {             quotes* newquotes =[[quotes alloc] init];              // add our new customer record our nsmutablearray             newquotes.quote = [onequote objectforkey:@"content"];             newquotes.filmname = [onequote objectforkey:@"film"];             [randomquotes addobject:newquotes];         }     }); });

you can random object out of array this.

nsuinteger randomindex = arc4random_uniform(thearray.count); [thearray objectatindex: randomindex];

as long keep array of quotes around, won't need hit web service again.

-
i've been using 2 methods render data. the first one: function name($id,$name){ return '<div id="'.$id.'">'.$name.'</div>'; } echo implode($pdo->query("select id,name user")->fetchall(pdo::fetch_func,'name')); the second one: $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); foreach($users $user){ echo name($user->id,$user->name); } i don't understand how pdo::fetch_func works. tried figure out. however, not well-documented. could please explain fetch mode? , also, 1 performs better? thank you. both methods wrong , have learn how use templates , how separate business logic presentation logic. $users = $pdo->query("select id,name user")->fetchall(pdo::fetch_obj); tpl::assign('users', $users); is code business logic part. then in template <?php foreach $users $row): ?> <div id="<?=$...
