ios - using storyboards -


i trying tutorial using story board ray. using tab bar controller connecting tableview embedded navigation controller, , table view named players , view controller connecting tab bar controller named gestures. displaying players game, name , rating in players tableview storing details in object. have created new file player base object store them properties have store properties in array of view controller called player view controller , have make array , test player objects in app delegate , assign playersviewcontroller’s players property using instance variable.so in appdelegate.m, imported player , player view controller.h headers , add new instance variable named _players. code in app delegate.m below error subscript requires size of interface 'nsarray' not constant in non-fragile abi @ line viewcontrollers[0]. 

#import "appdelegate.h" #import "player view controller.h" #import "player.h"  @implementation appdelegate {    nsmutablearray *_players; }  @synthesize window = _window;  - (bool)application:(uiapplication *)application didfinishlaunchingwithoptions:(nsdictionary *)launchoptions {    _players=[nsmutablearray arraywithcapacity:20];    player *player1=[[player alloc]init];    player1.name=@"name";    player1.game=@"cricket";    player1.rating=3;    [_players addobject:player1];    player1=[[player alloc]init];    player1.name=@"name";    player1.game=@"football";    player1.rating=3.5;    [_players addobject:player1];    player1=[[player alloc]init];    player1.name=@"tony";    player1.game=@"handball";    player1.rating=4;    [_players addobject:player1];    uitabbarcontroller *tabbarcontroller = (uitabbarcontroller *)self.window.rootviewcontroller;    uinavigationcontroller *navigationcontroller = [tabbarcontroller viewcontrollers][0];    uinavigationcontroller *navigationcontroller = [tabbarcontroller viewcontrollers][0]; /*at point error  [error: subscript requires size of interface 'ns array' not constant in non-fragile abi] */    player view controller *playersviewcontroller = [navigationcontroller viewcontrollers][0];      playersviewcontroller.players = _players;     return yes;

you can use below code

uinavigationcontroller *navigationcontroller =      [tabbarcontroller.viewcontrollers objectatindex:0];

refer below links..regarding error , explanation..!

what non-fragile abi?

subscript requires size of interface 'nsarray', not constant in non-stable abi

hope helps you...!

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.
