my class has bool property needs set class, trying use pointer. i'm declaring property this: @interface someclass : superclass { bool *_shared; } @property(nonatomic) bool *shared; is correct way this? i'd set , access value this: *self.shared = yes; or proper way set retainable property? no, not want send pointer instance variable other class can set instance variable. doing fragile , breaks encapsulation. awful design pattern. it unnecessary. if instance can "send pointer" instance b, instance can send reference instance b. there, instance b can [instancea setshared:yes]; . @interface b:uiviewcontroller @property(strong) *controllera; @end @interface a:uiviewcontroller @property bool dogdoorenabled; @end @implementation ... - (void) dosomething { b *b = .... instance of b ...; [b setcontrollera: self]; } @end @implementation b ... - (void) dosomethingelse { bool ischeeseonfire = ... calculate whether cheese burnin...

i have site users can share link homepage such http://example.com/user . currently, using php function filter_var($_post['url'], filter_validate_url) validate url before adding database using prepared statement. however, realize php filter function accepts input such http://example.com/<script>alert('xss');</script> used cross-site scripting. counter that, use htmlspecialchars on url within <a> tag , rawurlencode on href attribute of tag. but rawurlencode causes / in url converted %2f , makes url unrecognizable. thinking of doing preg_replace %2f / . way sanitize url display link? this outdated : i using php function filter_var($_post['url'], filter_validate_url) validate url before adding database using prepared statement. instead of filter_validate_url you can use following trick : $url = "your url" $validation = "/^(http|https|ftp):\/\/([a-z0-9][a-z0-9_-]*(?:\.[a-z0-9][a-z0-9_-]*)+):?...

generally detect collisions in canvas games use like: function collides(a, b) { return a.x < b.x + b.width && a.x + a.width > b.x && a.y < b.y + b.height && a.y + a.height > b.y; } but detects collisions if objects touching @ time frame processed. if have sprite speed (in pixels/frame) greater width of obstacle in path, pass through obstacle without collision being detected. how go checking what's in between sprite , destination? that's hard problem , high-quality solution box 2d library useful. a quick , dirty solution (that gives false positives on diagonally moving objects) — check collision between bounding boxes cover position of object in current and previous frame. instead of a.x use min(a.x, a.x - a.velocity_x) , instead of a.x + a.width use max(a.x + a.width, a.x + a.width - a.velocity_x) , etc. if object moving fast small (a bullet), test collision between line (from origin origin + velo...

i need return data (todays) table. i'm using query job not fast like. current query where (calldetail.dnis='456456') , calldetail.connecteddatetimegmt > cast(floor(cast(getdate() float))as datetime) another query use returns past weeks worth of data in matter of seconds. where (calldetail.localname='name') , (calldetail.connecteddate between dateadd(wk,-1,getdate()) , getdate()) is there more effective query can use return data today? instead of casting 2 times return date part getdate() slows down query where (calldetail.dnis='456456') , calldetail.connecteddatetimegmt > cast(floor(cast(getdate() float))as datetime) use faster way return date part getdate() where (calldetail.dnis='456456') , calldetail.connecteddatetimegmt > dateadd(dd, 0, datediff(dd, 0, getdate()))
