iPhone contains many useful features One of them is buildin camera and Camera application system for making photos It looks great but what about camera usage with native applications iPhone SDK provides the capability of using camera through UIImagePickerController class Thats great but there is a small disadvantage you cannot create a fullscreen persistent live camera view like the Camera application does Instead of that you should use UIImagePickerController only in modal mode show the popup modal view when you need a photo and close the view after the photo is made You have to reopen this view again to take the next one Moreover that modal view contains additional panels and controls that overlay the camera view Another disadvantage is you cannot take a photo in one touch you need to touch the Shoot button to take a picture and preview it and then you need to touch the Save button to get the photo for processing Probably its the best practice but I dont like it and I hope you think the same way What about using the UIImagePickerController as an ordinal nonmodal view controller under the navigation controller the same way as we use the other view controllers Try it and you will found that it works The camera view works and looks as it should You can assign a delegate and process UIImagePickerControllerDelegate events to get and save the photo Ok touch the Shoot button touch the Save button great youve got the photo But just look at this the Retake and Save buttons stay above the camera view and they dont work now when they are touched This is because you cannot reset the view to take another photo after taking one and touching the Save button the view is freezed and the buttons are disabled It seems you need to fully recreate the UIImagePickerController instance to take another photo Thats not so simple and not so good And you still need to use the panels and buttons that overlay the camera view Now I have an idea When we touch Shoot the view stops refreshing and displays single image from the camera then we have to touch Retake or Save button Can we get that image and save it without using the UIImagePickerControllerDelegate and then touch the Retake button programmatically to reset the view and get another photo Sure we can If you explore the camera views hierarchy after touching Shoot you will find that there is a hidden view of ImageView type This class is not described in the SDK but we can explore its methods using ObjectiveC capabilities We can see that the class contains a method called imageRef Lets try this Yes it returns CGImage object And the image size is x its definitely the camera picture Ok now we know we can get the photo without UIImagePickerControllerDelegate But in what moment should we do this Can we catch the user touches on the Shoot button to start processing Its possible but not so good Do you remember our main purpose creating the persistent fullscreen camera view like system Camera application does Its time to do it When we explored the views hierarchy weve found that there are number of views above the camera view We can try to hide these views and create our own button below the camera view to take the photo in one touch But how can we force the camera view to make the photo Its very simple we can get the corresponding selector from the Shoot button and call it from our action handler Ok weve forced getting the image But it takes us few seconds How can we detect that the image is ready It occurred when the Cancel and Shoot buttons are replaced by Retake and Save ones The simplest way to detect this is starting a timer with short interval and checking the buttons And then we can get and save the photo using the corresponding selector from the Retake button and calling it to reset the camera view and prepare it for making a new one Here is the code Shot button on the toolbar touched Make the photo voidshotActionidsender self enableInterfaceNO Simulate touch on the Image Pickers Shot button UIControl camBtn self getCamShutButton camBtn sendActionsForControlEventsUIControlEventTouchUpInside Set up timer to check the camera controls to detect when the image from the camera will be prepared Image Pickers Shot button is passed as userInfo to compare with current button NSTimer scheduledTimerWithTimeInterval targetself selectorselectorsavePhotoTimerFireMethod

buttons UIViewfindCamControlsLayerViewUIViewview Class cl view class NSString desc cl description if desc comparePLCropOverlay NSOrderedSame return view for NSUInteger i i Another important question is in what moment can we hide the overlaying camera views and controls and create our own button Trying the viewDidLoad Oops The camera view is still not created Trying the viewWillAppear The same thing Trying the viewDidAppear Yes the views have been created and can be hidden now Ok we hide that and create a toolbar with our Shoot button It works but the screen flicks we see how the standard views and buttons are shown and then hidden How can we prevent this I tried a number of ways and had found the best one we should hide the views before they are added to the camera view when the addSubview method of the camera view is called Its possible using ObjectiveC capability to replace the method dynamically at runtime Ok lets replace the addSubview by our own method In our method we can check that the passed view is one of the camera view subviews and set its hidden property to YES So we replace the addSubview in the viewWillAppear before the camera view is created And we create our toolbar and Shoot button in the viewDidAppear after the camera view is created Take a look at the code below Replace addSubview if called first time hide camera controls otherwise voidviewWillAppearBOOLanimated super viewWillAppearanimated if toolBar nil The view was already appeared we dont need to subclass UIView but need to hide extra camera controls UIView cameraView self findCamControlsLayerViewselfview if cameraView cameraView cameraViewsuperview int cnt cameraViewsubviews count if cnt for int i i The complete demo project here It was created as NavigationBased Application Please notice that all the implementation files were renamed from m to mm to make their ObjectiveC instead of ObjectiveC because I prefer C The technique described above was used in
