Proposer

Proposer provides a simple API to request permission for access Camera, Photos, Microphone, Contacts, Location.

Requirements

Swift 1.2, iOS 8.0

Example

Only one single API:

proposeToAccess(_:agreed:rejected:)

In real world:

import Proposer

@IBAction func choosePhoto() {

    let photos: PrivateResource = .Photos

    proposeToAccess(photos, agreed: {
        if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.SavedPhotosAlbum) {
            let imagePicker = UIImagePickerController()
            imagePicker.sourceType = .SavedPhotosAlbum

            self.presentViewController(imagePicker, animated: true, completion: nil)
        }

    }, rejected: {
        self.alertNoPermissionToAccess(photos)
    })
}

When you want to get user's location, thanks to Swift's enum, you can even choose the usage mode:

@IBAction func shareLocation() {

    let location: PrivateResource = .Location(.WhenInUse)
    
    proposeToAccess(location, agreed: {
        print("I can access Location. :]\n")
        
    }, rejected: {
        self.alertNoPermissionToAccess(location)
    })
}

Depending on your needs, you must add a NSLocationWhenInUseUsageDescription or NSLocationAlwaysUsageDescription to your Info.plist

See the demo for more information.

I recommend you add a UIViewController+Proposer.swift file (like the demo) for show localized alert before the first proposal or when propose failed.

Installation

Feel free to drag Proposer.swift to your iOS Project. But it's recommended to use CocoaPods or Carthage.

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

CocoaPods 0.36 adds supports for Swift and embedded frameworks. You can install it with the following command:

$ [sudo] gem install cocoapods

To integrate Proposer into your Xcode project using CocoaPods, specify it in your Podfile:

source 'https://github.com/CocoaPods/Specs.git'
platform :ios, '8.0'
use_frameworks!

pod 'Proposer', '~> 0.6.2'

Then, run the following command:

$ pod install

You should open the {Project}.xcworkspace instead of the {Project}.xcodeproj after you installed anything from CocoaPods.

For more information about how to use CocoaPods, I suggest this tutorial.

Carthage

Carthage is a decentralized dependency manager for Cocoa application. To install the carthage tool, you can use Homebrew.

$ brew update
$ brew install carthage

To integrate Proposer into your Xcode project using Carthage, specify it in your Cartfile:

github "nixzhu/Proposer" >= 0.6.2

Then, run the following command to build the Proposer framework:

$ carthage update

At last, you need to set up your Xcode project manually to add the Proposer framework.

On your application targets’ “General” settings tab, in the “Linked Frameworks and Libraries” section, drag and drop each framework you want to use from the Carthage/Build folder on disk.

On your application targets’ “Build Phases” settings tab, click the “+” icon and choose “New Run Script Phase”. Create a Run Script with the following content:

/usr/local/bin/carthage copy-frameworks

and add the paths to the frameworks you want to use under “Input Files”:

$(SRCROOT)/Carthage/Build/iOS/Proposer.framework

For more information about how to use Carthage, please see its project page.
