ios - Horizontal Camera with Overlay -


i need have horizontal video camera input image overlays (that not recorded).

the problem that, when active, camera view rotated 90 degrees though else correctly oriented horizontally.

uiimagepicker cannot horizontal orientation, , i've had trouble using avcapture graphic overlays. so, use custom view , rotate that.

camera init

 if ([uiimagepickercontroller issourcetypeavailable:uiimagepickercontrollersourcetypecamera])  {     //custom view instead of uiimagepicker     _video_picker = [[vcimagepickercontroller alloc] init];      _video_picker.delegate = self;     _video_picker.allowsediting = yes;     _video_picker.sourcetype = uiimagepickercontrollersourcetypecamera;     _video_picker.cameradevice = uiimagepickercontrollercameradevicefront;     _video_picker.mediatypes = [[nsarray alloc] initwithobjects: (nsstring *) kuttypemovie, nil];     _video_picker.showscameracontrols = no;      //set orientation     _video_picker.modalpresentationstyle = uimodalpresentationcurrentcontext;      //display overlay graphics     _video_picker.cameraoverlayview = _overvw ;      [self.navigationcontroller presentviewcontroller:_video_picker animated:no completion:nil];

then in custom vcimagepickercontroller view, mask set:

- (bool)shouldautorotate {     return yes; }  -(uiinterfaceorientationmask)supportedinterfaceorientations {     return uiinterfaceorientationmasklandscape;   }  - (uiinterfaceorientation)preferredinterfaceorientationforpresentation {     return uiinterfaceorientationlandscaperight; }

when camera in horizontal mode, rendered view out of sync. mask appears, actual camera view incorrect. when move camera right, goes down, if orientation rotated. using iphone 6 ios 9.2.1.

if helps anyone, make horizontal uiimagepicker , must create entirely custom view.

ios - Realm over CoreData should I use NSFetchedResultController or a Dictionary? -
