Usage

Permission

Permission.swift PermissionStatus.swift

let permission: Permission = .Contacts

print(permission.status) // PermissionStatus.NotDetermined

permission.request { status in
    switch status {
    case .Authorized:    print("authorized")
    case .Denied:        print("denied")
    case .Disabled:      print("disabled")
    case .NotDetermined: print("not determined")
    }
}

Supported permissions:

PermissionType.swift PermissionTypes/

• Bluetooth
• Camera
• Contacts
• Events
• Motion
• Microphone
• Notifications
• Photos
• Reminders
• LocationAlways
• LocationWhenInUse

PermissionAlert

PermissionAlert.swift

When you first request a permission, a system alert is presented to the user. If you request a permission that was denied/disabled, a PermissionAlert will be presented. You might want to change the default title, message, cancel and settings text:

let alert = permission.deniedAlert // or permission.disabledAlert

alert.title    = "Please allow access to your contacts"
alert.message  = nil
alert.cancel   = "Cancel"
alert.settings = "Settings"

PermissionSet

PermissionSet.swift

Use a PermissionSet to check the status of a group of Permission and to react a permission is requested.

let permissionSet = PermissionSet(.Contacts, .Camera, .Microphone, .Photos)
permissionSet.delegate = self

print(permissionSet.status) // PermissionStatus.NotDetermined

// ...

func permissionSet(permissionSet: PermissionSet, willRequestPermission permission: Permission) {
    print("Will request \(permission)")
}

func permissionSet(permissionSet: PermissionSet, didRequestPermission permission: Permission) {
    switch permissionSet.status {
    case .Authorized:    print("all the permissions are granted")
    case .Denied:        print("at least one permission is denied")
    case .Disabled:      print("at least one permission is disabled")
    case .NotDetermined: print("at least one permission is not determined")
    }
}

PermissionButton

PermissionButton

A PermissionButton requests the permission when tapped and updates itself when its underlying permission status changes.

let button = PermissionButton(.Photos)

PermissionButton is a subclass of UIButton. All the getters and setters of UIButton have their equivalent in PermissionButton.

button.setTitles([
    .Authorized:    "Authorized",
    .Denied:        "Denied",
    .Disabled:      "Disabled",
    .NotDetermined: "Not determined"
])

// button.setAttributedTitles
// button.setTitleColors
// button.setTitleShadowColors
// button.setImages
// button.setBackgroundImages
// etc.

Example

class PermissionsViewController: UIViewController, PermissionSetDelegate {

    let label = UILabel()

    override func viewDidLoad() {
        let contacts   = PermissionButton(.Contacts)
        let camera     = PermissionButton(.Camera)
        let microphone = PermissionButton(.Microphone)
        let photos     = PermissionButton(.Photos)

        // ...

        let permissionSet = PermissionSet(contacts, camera, microphone, photos)

        permissionSet.delegate = self

        label.text = String(permissionSet.status)
    }

    func permissionSet(permissionSet: PermissionSet, didRequestPermission permission: Permission) {
        label.text = String(permissionSet.status)
    }
}
