ios - How to disable multi click on button? -


i have uitableview:

cell 1: button 1->push view controller a

cell 2: button 2->push view controller b

it works fine. however, when try hold , press 2 buttons @ same time, app receives following warning:

nested push animation can result in corrupted navigation bar. finishing navigation transition in unexpected state. navigation bar subview tree might corrupted.

how should disable multi click button on cell ?

you need disable button while pushing view controller. can create category ofuinavigationcontroller pushing view controller. make sure enable button before coming current viewcontroller

@interface uinavigationcontroller (completionhandler)  - (void)pushviewcontroller:(uiviewcontroller *)viewcontroller               animated:(bool)animated             completion:(void (^)(void))completion;  @end     @implementation uinavigationcontroller (completionhandler) - (void)pushviewcontroller:(uiviewcontroller *)viewcontroller animated:(bool)animated completion:(void (^)(void))completion { [catransaction begin]; [catransaction setcompletionblock:completion]; [self pushviewcontroller:viewcontroller animated:animated]; [catransaction commit]; }   @end

call below code pushing viewcontroller

[self.navigationcontroller pushviewcontroller:controllerobj animated:yes completion:^{         btn.userinteractionenabled = no; // button object         nslog(@"completed");     }];

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.
