sprite kit - SKSpriteNode removeFromParent in touchesEnded -

-

i have issue removing skspritenode it's parent when touch detected on skspritenode. here code:

-(void)touchesended:(nsset *)touches withevent:(uievent *)event {     (uitouch *touch in touches) {          cgpoint scenelocation = [touch locationinnode:self];         if ([_tabledonebutton containspoint:scenelocation]) {             nslog(@"here");             [self removeitemsfromview];             _headernode.portlabel.text = [ipgamemanager sharedgamedata].world.player.port.name;             [_portnode show];         }          sknode *nodeinport = [_portnode nodeatpoint:[touch locationinnode:_portnode]];         if ([nodeinport.name isequaltostring:@"marketbutton"]) {             [self showmarket];         }     } }

in showmarket function, 'done' skspritenode added user can leave market when he/she wants to. can see above, if _tabledonebutton contains touch location, should call removeitemsfromview function contains [_tabledonebutton removefromparent];. have special when removing nodes way?

another issue: seems removed ~1 second later. happens when run [node removefromparent]? if set skspritenode nil after call [self removeitemsfromview] works fine. shouldn't have that?

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