many posts seem advise against notifications when trying synchronize functions, there other posts caution against closure callbacks because of potential inadvertently retain objects , cause memory issues. assume inside custom view controller function, foo , uses bar class data server. class customviewcontroller : uiviewcontroller { function foo() { // other stuff // use bar data server bar.getserverdata() } } option 1: define getserverdata accept callback. define callback closure inside customviewcontroller . option 2: use nsnotifications instead of callback. inside of getserverdata , post nsnotification when server returns data, , ensure customviewcontroller registered notification. option 1 seems desirable reasons people caution against nsnotification (e.g., compiler checks, traceability), doesn't using callback create potential issue customviewcontroller unnecessarily retained , therefore potentially creating memory issues?

i have seen in few mvc frameworks class hotel{ function add(addrequest $post){ $this->save($post->all()); } } i create own type hinting using php class bellow , know there 2 ways it. with class: public function myfunction(someclass $instance) with interface: public function myfunction(someinterface $instance) i couldn't find article it.can explain briefly on how create our own type hinting , advantages doing so. the first benefit of using type hinting validation , self-documentation comes i.e. if come code haven't seen in while or working on else's code able see straight away must passed instance of specific. second being, if not pass required instance throw error. (this without code) furthermore, use of interfaces allows different implementations of class passed through code allow because interface should declare required methods (think different db drivers). i've not used yii before don't know it. laravel, on other hand, work
