ios - iPhone Camera App - how to stay in Camera view? -

i've implemented camera inside of app default showscameracontrols = yes, , issue having when user confirms image keeper, dismisses camera [self.delegate didfinishwithcamera]. remain in camera view until user done taking photos. without [self.delegate didfinishwithcamera], app hangs after user confirms want keep photo , never returns live camera feed. how remain in camera view? appreciated!

@implementation phfphotooverlayvc  - (id)initwithnibname:(nsstring *)nibnameornil bundle:(nsbundle *)nibbundleornil {     self = [super initwithnibname:nibnameornil bundle:nibbundleornil];     if (self) {         self.imagepickercontroller = [[uiimagepickercontroller alloc] init];         self.imagepickercontroller.delegate = self;     }     return self; }  - (void)setupimagepicker:(uiimagepickercontrollersourcetype)sourcetype {     self.imagepickercontroller.sourcetype = sourcetype;      if (sourcetype == uiimagepickercontrollersourcetypecamera)     {         self.imagepickercontroller.mediatypes =             [nsarray arraywithobjects:(nsstring *) kuttypeimage, nil];         self.imagepickercontroller.showscameracontrols = yes;  #if false         if ([[self.imagepickercontroller.cameraoverlayview subviews] count] == 0)         {             cgrect overlayviewframe = self.imagepickercontroller.cameraoverlayview.frame;             cgrect newframe = cgrectmake(0.0,                                          cgrectgetheight(overlayviewframe) -                                          self.view.frame.size.height - 10.0,                                          cgrectgetwidth(overlayviewframe),                                          self.view.frame.size.height + 10.0);             self.view.frame = newframe;             [self.imagepickercontroller.cameraoverlayview addsubview:self.view];         } #endif     } }   #pragma mark - #pragma mark uiimagepickercontrollerdelegate  - (void)    imagepickercontroller:(uiimagepickercontroller *)picker     didfinishpickingmediawithinfo:(nsdictionary *)info {     self.imagepickercontroller.mediatypes =         [nsarray arraywithobjects:(nsstring *) kuttypeimage, nil];     self.imagepickercontroller.showscameracontrols = yes;       uiimage *image = [info valueforkey:uiimagepickercontrolleroriginalimage];     if (self.delegate)         [self.delegate didtakepicture:image];      [self.delegate didfinishwithcamera]; }  - (void)imagepickercontrollerdidcancel:(uiimagepickercontroller *)picker {     [self.delegate didfinishwithcamera]; }  @end 

in order achieve this, have implement own method taking picture, since default button causes view dismiss itself.

obviously, can setting showscameracontrols=no, you'd have recreate other functionality still want.

i've never done this, should possible leave showscameracontrols=yes , use cameraoverlayview layer identical "take picture" button on existing one. if that, need have button call method -takepicture instance of uiimagepickerviewcontroller.

hopefully that's enough, feel free comment , ask clarification.
