I am taking picture using UIImagePickerController with custom overlay view. I have a requirement to enable native editing mode of UIImagePickerController when photo is taken and user taps "Edit" button which is on my custom overlay view.
I have set:
imagePickerController.showsCameraControls = NO;
How is this possible to achieve?
Thanks,
You might be trying using UIImagePickerController. But I know this one solution to your problem. You can do it easily using AVCamCaptureManager and AVCamRecorder classes. Apple has a demo program build on its developer site here. It is named AVCam. In simple words what it does is when you click to open the camera, it calls the classes and methods which are responsible for opening the iPhone's camera and record video or capture audio. It calls the same classes which are called by UIImagePickerController. So your camera will open and start taking input.
Now, if you open the xib file of that AVCam project, you'll find a small UIView object. This view is responsible for displaying the camera's feed. You can resize that view as per the size you want and the camera's input will be displayed in that much area. You can also put the frame image around it as per your choice.
It worked for me when I wanted to resize the camera's input feed and capture photos. I hope it works for you as well.

I am developing an app that has an internal gallery with some images.
What I want to achieve is exactly a result that behaves and looks like the Apple Photo app image viewer.
With a collection view I implemented the gallery images with thumbnails and now I would like to show the image on fullscreen on press.
The image viewer should have exactly the Apple's Photo behavior:
Full screen on single tap,
Delete, Share button etc...
Pinch to zoom, double tap zoom...
My question is. Is that really possible that such a common feature is not already given by iOS? Is there maybe a view controller already build in that we can use but I am not aware of?
I know there are some libraries around that make such thing, but I'm wondering if there's already something given.
I'm wondering how I can add the default Library picker button that can be found on an iPhone's default Camera app(can also be accessed via dashboard). The button looks like this, though this is an app custom implementation:
So I know that it can be done, but how? It's the library image picker that you can see the taxi car in. I'm using a completely customized UIImagePickerController through the use of the imagePickerController's property customOverlay view and I need to add this very same button to my overlayView. If someone could guide me towards a solution that'd be of great help, thanks!
I can imagine using UIImagePickerControllerSourceTypePhotoLibrary for the button and simply setting the button's imageView property to the first picture in the camera roll, but how would I go about doing this?
Also, is this somehow controllable by iOS default UIImagePickerController
I am looking for a way to add a custom button on camera preview and don't know where to go. Just like the iOS native camera, on the left of the capture button, you can click on it and access photo library. How can we add a button to the camera preview view? Would anyone be kind enough to give some directions? Thanks in advance.
Take a look at UIImagePickerController's cameraOverlayView. This lets you lay your own interface on top of the default camera interface.
Check out this sample project. It shows the preview of the camera in a custom UIView and uses AVCaptureSession for the management of the video preview. You can add whatever you want in the custom UIView as you like.
I want my camera ui will have the regular Camera Roll button. The one that you have when you open the camera app. Is there a simple way doing that or I'll have to use a custom layer? Tried searching in the documentation without success.
There is not an easy way to do it. You should implement your own custom toolbar to replicate the camera app behavior. You should use the overlay view property of the imagePicker. Have a look at this link for a possible implementation
I'd like to avoid the use/retry view after the picture is taken without disabling the default Apple camera controls that let me take the picture.
Doing this:
imagePicker.showsCameraControls = NO;
Causes ALL the camera controls to disappear. Is there any other method?
Unfortunately there is no proper way to do this provided by Apple. So here are you options:
showCameraControls = NO and adding your own controls.
go hardcore and use AVFoundation - but again you'll need your own controls - probably not what you're looking to do but if you're interested I have a sample app of this here:
https://github.com/Shein/CameraFeedUnderlay
Hack around it - place YOUR OWN button on top of camera control play button and override the action to take the picture as you would without camera controls and directly dismiss the UIImagePickerController.
There's a sort-of example of this solution here:
iPhone SDK - How to disable the picture preview in UIImagePickerController?
Perhaps this helps. You can use imagePicker.showsCameraControls = YES; in collaboration with NSNotificationCenter listening to #"_UIImagePickerControllerUserDidCaptureItem" and #"_UIImagePickerControllerUserDidRejectItem".
When entering the #"_UIImagePickerControllerUserDidCaptureItem" state, you could then dismiss the UIImagePickerController.
I had a similar problem, hiding a overlay when entering the preview view. I could solve the problem with this approach.
You can customize an image picker controller to manage user interactions yourself. To do this, provide an overlay view containing the controls you want to display, and use the methods described in “Capturing Still Images or Movies.” You can display your custom overlay view in addition to, or instead of, the default controls. Custom overlay views for the UIImagePickerController class are available in iOS 3.1 and later by way of the cameraOverlayView property. For a code example, see the PhotoPicker sample code project.
from this you can create your own customCameraView to show your own controls that you need to show
