ios - EKEventEditViewController freezes app and loads after long time -


i have following code in swift: 

    var eventcontroller = ekeventeditviewcontroller()     eventcontroller.editviewdelegate = self     var store = ekeventstore()     eventcontroller.eventstore = store      var event = ekevent(eventstore: store)     event.title = viewmodel.rolename     event.location = viewmodel.location     event.startdate = viewmodel.startdate     event.enddate = viewmodel.enddate     eventcontroller.event = event      var status = ekeventstore.authorizationstatusforentitytype(ekentitytypeevent)     switch status {     case .authorized:         self.setnavbarappearancestandard()                     dispatch_async(dispatch_get_main_queue(), { () -> void in             self.presentviewcontroller(eventcontroller, animated: true, completion: nil)         })     case .notdetermined:         store.requestaccesstoentitytype(ekentitytypeevent, completion: { (granted, error) -> void in             if granted == true {                 self.setnavbarappearancestandard()                 dispatch_async(dispatch_get_main_queue(), { () -> void in                     self.presentviewcontroller(eventcontroller, animated: true, completion: nil)                 })             }         })     case .denied, .restricted:         uialertview(title: "access denied", message: "permission needed access calendar. go settings > privacy > calendars allow access collective app.", delegate: nil, cancelbuttontitle: "ok").show()         return     }

it's pretty straight forward. works on simulator. when try run code on device, whole ui freezes , after 1 minute edit event view controller comes up, , not @ all.

please help.

after bit of digging i've manager figure out eventstore (ekeventstore) variable must instance variable or global var in singleton class. if local var take forever present view controller. optimisation issues on sdk.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
