About

This project is about managing permissions with customizable visual effects. Simple pod saves your hours of development. You can start using this project with just two lines of code and easy customization! You can watch how I design UI for this pod on YouTube.

Preview GIF is loading 4mb. Please wait.

I have a store where I sell applications and modules for Xcode projects. You can find source codes of applications or custom animations / UI. I regularly update the code. Visit my website to see all items for sale: xcode-shop.com. On the website you can find previews and, for some items, links to AppStore.

Requirements

Swift 4.2. Ready for use on iOS 10+

Integration

Put Source/SPPermission folder in your Xcode project. Make sure to enable Copy items if needed and Create groups.

Or via CocoaPods:

pod 'SPPermission'

How to use

Call SPPermission and use func request(). Also, pass the controller on which the dialog should present:

import UIKit
import SPPermission

class ViewController: UIViewController {

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        SPPermission.Dialog.request(with: [.camera, .microphone, .notification], on: self)
    }
}

If you want to know if permission is allowed, you need to call the function:

let isAllowedCamera = SPPermission.isAllowed(.camera)

If you want to know if permission is denied, you need to call the function:

let isDeniedMicrophone = SPPermission.isDenied(.microphone)

To learn how to customize titles and images you can read section DataSource & Customization

Permissions

If you want to request notification (or other permissions) without dialog, use the function:

SPPermission.request(.notification, with: {
    // Callback
})

If you want new permission added, create new issue here

Delegate

To track events of hiding & allowing permissions associated with SPPermission, implement protocol SPPermissionDialogDelegate:

@objc public protocol SPPermissionDialogDelegate: class {

    @objc optional func didHide()
    @objc optional func didAllow(permission: SPPermissionType)
    @objc optional func didDenied(permission: SPPermissionType)
}

And pass the delegate to the function:

SPPermission.Dialog.request(
    with: [.calendar, .microphone],
    on: self,
    delegate: self
)

DataSource & Customization

If you want to change the text, you need to implement SPPermissionDialogDataSource protocol. Override needed parameters to see the changes:

@objc public protocol SPPermissionDialogDataSource: class {

    @objc optional var dialogTitle: String { get }
    @objc optional var dialogSubtitle: String { get }
    @objc optional var dialogComment: String { get }
    @objc optional var allowTitle: String { get }
    @objc optional var allowedTitle: String { get }
    @objc optional var bottomComment: String { get }
    @objc optional var showCloseButton: Bool { get }
    @objc optional var dragEnabled: Bool { get }
    @objc optional func name(for permission: SPPermissionType) -> String?
    @objc optional func description(for permission: SPPermissionType) -> String?
    @objc optional func image(for permission: SPPermissionType) -> UIImage?
    @objc optional func deniedTitle(for permission: SPPermissionType) -> String?
    @objc optional func deniedSubtitle(for permission: SPPermissionType) -> String?
    @objc optional var cancelTitle: String { get }
    @objc optional var settingsTitle: String { get }
}

And pass the object to the function:

SPPermission.Dialog.request(
    with: [.photoLibrary, .contacts],
    on: self,
    delegate: self,
    dataSource: self
)

If you want to inhibite drag gesture to discard the dialog view you need to override dragEnabled parameter, and if you want to add or remove the close button (without the button you’ll have to swipe the dialog to close it), you need to override parameter showCloseButton. To see what it looks like, see the picture below:

In the project you can find an example of usage of SPPermissionDialogDataSource

Colors

If you want to change the color scheme, you need to implement the protocol SPPermissionDialogColorSource. It is not necessary to override all parameters, you can only change those that are necessary:

@objc public protocol SPPermissionDialogColorSource: class {
    
    @objc optional var whiteColor: UIColor { get }
    @objc optional var blackColor: UIColor { get }
    @objc optional var baseColor: UIColor { get }
    @objc optional var grayColor: UIColor { get }
    @objc optional var lightGrayColor: UIColor { get }
    
    @objc optional var iconWhiteColor: UIColor { get }
    @objc optional var iconLightColor: UIColor { get }
    @objc optional var iconMediumColor: UIColor { get }
    @objc optional var iconDarkColor: UIColor { get }
}

Will auto check SPPermissionDialogDataSource also implement SPPermissionDialogColorSource. You need pass for dataSource object, which implements two protocols.

Purpose String in Info.plist

SPPermission uses many permissions in one library; you need to add some strings to the Info.plist file with description. List of keys:

  • NSContactsUsageDescription
  • NSCalendarsUsageDescription
  • NSMicrophoneUsageDescription
  • NSAppleMusicUsageDescription
  • NSSpeechRecognitionUsageDescription
  • NSMotionUsageDescription

If I forgot to mention some, please let me know and create issue or pull request.

YouTube Video

I have YouTube channel where I publish videos about Xcode and Design. You can see how I develop native design for SPPermission dialog view:

My projects

Here I would like to offer you my other projects.

SPStorkController

I created SPStorkController. It is a modal controller like in Mail or Apple Music application. Similar animation and transition. You can see an example of using controller in app in AppStore.

You can buy source code of this app on xcode-shop.com. Price: $200.

SparrowKit

SPPermission was formerly a part of SparrowKit library. In the library you can find many useful extensions & classes. To install via CocoaPods use:

pod 'SparrowKit'
