ios - capture image is not working properly.? -


hi new developing ios application please me. facing problem regarding capturing image using uiimagepicker. have integrated hip mob app in our application.

in window want show uibutton user click on uibutton should capture image. when click on button throwing message (whose view not in window hierarchy!).

i think happens due chat window. here code snippet.!

[[hmservice sharedservice] openchat:self withsetup:^(hmchatviewcontroller * controller) {  controller.chatdelegate = self;  controller.chatview.receivedmessagefont = [uifont systemfontofsize:20.0];  controller.navigationbarhidden = yes;  uiview * viewobjforvehicledetails = [[uiview alloc]init];  uibutton * btnforcaputrephoto = [[uibutton alloc]init];  [btnforcaputrephoto addtarget:self action:@selector(capturephotoimage) forcontrolevents:uicontroleventtouchupinside];   btnforcaputrephoto.frame = cgrectmake(55, 90, 103, 85);  [controller.chatview addsubview:viewobjforvehicledetails];  [viewobjforvehicledetails addsubview:btnforcaputrephoto];  [[controller.chatview table] registerclass:[chattableviewcell class] forcellreuseidentifier:@"reusechattableviewcell"];  }     -(void)capturephotoimage { uiimagepickercontroller *picker = [[uiimagepickercontroller alloc] init]; picker.delegate = self; picker.allowsediting = yes; picker.sourcetype = uiimagepickercontrollersourcetypecamera; [self presentviewcontroller:picker animated:no completion:nil];  }      - (void)imagepickercontroller:(uiimagepickercontroller *)picker didfinishpickingmediawithinfo:(nsdictionary *)info { [picker dismissviewcontrolleranimated:yes completion:null]; }

thanks in advance.!

first sure using following delegate in view controller

<uinavigationcontrollerdelegate, uiimagepickercontrollerdelegate>

secondly use line show imagepicker:-

[self presentmodalviewcontroller:picker animated:yes];

alternative way:-

[self.view addsubview:imagepicker.cameraoverlayview]

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.
