How to check if the user gave permission to use the camera?

Question

Trying to write this:

if usergavepermissiontousercamera     opencamera else    showmycustompermissionview 

Couldn't find a current way to do this simple task.
Note: Should also work iOS7 even if it requires a different method

Answer 1

You can use the following code for doing the same:

if AVCaptureDevice.authorizationStatusForMediaType(AVMediaTypeVideo) ==  AVAuthorizationStatus.Authorized {     // Already Authorized } else {     AVCaptureDevice.requestAccessForMediaType(AVMediaTypeVideo, completionHandler: { (granted: Bool) -> Void in        if granted == true {            // User granted        } else {            // User rejected        }    }) } 

NOTE:

1. Make sure that you add the AVFoundation Framework in the Link Binary section of build phases
2. You should write import AVFoundation on your class for importing AVFoundation

SWIFT 3

if AVCaptureDevice.authorizationStatus(forMediaType: AVMediaTypeVideo) ==  AVAuthorizationStatus.authorized {    // Already Authorized } else {    AVCaptureDevice.requestAccess(forMediaType: AVMediaTypeVideo, completionHandler: { (granted: Bool) -> Void in       if granted == true {          // User granted       } else {          // User Rejected       }    }) } 

Swift 4

if AVCaptureDevice.authorizationStatus(for: .video) ==  .authorized {     //already authorized } else {     AVCaptureDevice.requestAccess(for: .video, completionHandler: { (granted: Bool) in         if granted {             //access allowed         } else {             //access denied         }     }) }
