objective c - Random number generator method -

-

so have method returns letter (from a-z) creating random number between 1-26 , indexing string array pull out letter. problem not generate new letter when method called. how can generate new letter every time method called, in while loop. here code:

-(nsstring *)alphagenerator{     nsuinteger randomletterinteger = arc4random_uniform(26);     nsarray *alphabet = @[@"a",@"b",@"c",@"d",@"e",@"f",@"g",@"h",@"i",@"j",@"k",@"l",@"m",@"n",@"o",@"p",@"q",@"r",@"s",@"t",@"u",@"v",@"w",@"x",@"y",@"z"];     nsstring *alpha = alphabet[randomletterinteger];     return alpha; }

also, how convert number returned count method number can plug arc4random_uniform method? receive 'incompatible integer pointer inversion initializing...' error. have this:

-(nsuinteger)numofdictions{     nsstring *alpha = [self alphagenerator];     nsuinteger numb = [cuisines[alpha] count];     nsuinteger *randomnumofdictions = arc4random_uniform(numb);     return *randomnumofdictions; }

these 2 lines:

nsuinteger *randomnumofdictions = arc4random_uniform(numb); return *randomnumofdictions;

should be:

nsuinteger randomnumofdictions = arc4random_uniform(numb); return randomnumofdictions;

nsinteger not object type. it's primitive type.

php - render data via PDO::FETCH_FUNC vs loop -

-
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 $row): ?> <div id="<?=$...
