Storage permission on iOS

[sido420]

How difficult is it to add storage permission support on iOS?

I have never done native app development but can try.

[sido420]

Here https://github.com/NathanaelA/nativescript-permissions/issues/12, its been claimed that (as of Aug 2016) those are the only iOS permissions.

Can we get inspiration from @roblav96's code?

@sido420 I found this in an old project, might help get you started.

permissions.extension.ios.ts

import { Application, Device } from '@nativescript/core'

const _contactStore: CNContactStore = CNContactStore.alloc().init()

function _getContactsAuthorization(): CNAuthorizationStatus {
    return CNContactStore.authorizationStatusForEntityType(CNEntityType.Contacts)
}

export function isContactsAuthorized(): boolean {
    return _getContactsAuthorization() == CNAuthorizationStatus.Authorized
}

export function isContactsDenied(): boolean {
    let status: CNAuthorizationStatus = _getContactsAuthorization()
    let denied: boolean =
        status == CNAuthorizationStatus.Denied || status == CNAuthorizationStatus.Restricted
    return denied
}

export function requestContactsAuthorization(): Promise<boolean> {
    if (_getContactsAuthorization() == CNAuthorizationStatus.Authorized) {
        return Promise.resolve(true)
    } else {
        return new Promise((resolve) => {
            _contactStore.requestAccessForEntityTypeCompletionHandler(
                CNEntityType.Contacts,
                function completionHandler(result: boolean, error: NSError): void {
                    if (error) {
                        console.error('requestAccessForEntityTypeCompletionHandler > error', error)
                        resolve(false)
                    } else {
                        resolve(result)
                    }
                },
            )
        })
    }
}

export function isPhotosAuthorized(): boolean {
    return PHPhotoLibrary.authorizationStatus() == PHAuthorizationStatus.Authorized
}

export function isPhotosDenied(): boolean {
    let status: PHAuthorizationStatus = PHPhotoLibrary.authorizationStatus()
    let denied: boolean =
        status == PHAuthorizationStatus.Denied || status == PHAuthorizationStatus.Restricted
    return denied
}

export function requestPhotosAuthorization(): Promise<boolean> {
    return new Promise(function (resolve) {
        PHPhotoLibrary.requestAuthorization(function (status: number): void {
            let authed: boolean = status == PHAuthorizationStatus.Authorized
            resolve(authed)
        })
    })
}

export function isNotificationsAuthorized(): boolean {
    let nativeApp: UIApplication = Application.ios.nativeApp
    let version = parseFloat(Device.osVersion)
    if (version >= 8) {
        let enabled = nativeApp.registeredForRemoteNotifications
        let types = nativeApp.currentUserNotificationSettings.types
        return enabled && types != UIUserNotificationType.None
    }
    let types = nativeApp.enabledRemoteNotificationTypes()
    return types != UIRemoteNotificationType.None
}

Will look at it. Also this plugin is a direct port of the react native one. Need to see if they added since then.

@sido420 are we talking about ios13 external storage permissions? Do you have example native code?

[sido420]

Thanks for looking into it.

I was referring to iOS external storage in general. From the chart in this module, it appears storage permission for iOS is not supported, hence I wanted to request adding support for that. I don't know version differences in iOS and not sure if permission is even required for iOS.

I'm afraid, I don't have native code available, since I am still learning NS development. However, there is some discussion on storage at https://cordova.apache.org/docs/en/latest/reference/cordova-plugin-file/index.html#ios-quirks.

@sido420 ok. So i dont think it is needed , thus the graph here.

[sido420]

Just to clarify: Everything in https://github.com/nativescript-community/nativescript-perms#supported-permissions-types that has cross with it means it does not require a permission by the platform. Please confirm.

[farfromrefug]

Yes that s it. And you can "request" permission still. It will return "true" if not needed by the platform
