Installation - Via Cocoapods

Follow the instructions below to properly integrate GoogleDriveBrowser into your project.

 pod ‘GoogleDriveBrowser’

Google Configuration (Both Objective C and Swift)

1. Configure Google Drive (Follow the Step 1)Turn on the Drive API and setup your app. Follow the Step 1

2. Drag and drop downloaded Credentials.plist file into your project

3. Open the Credentials.plist file, and look for the REVERSED_CLIENT_ID key. Copy the value of that key, and paste it into the URL Schemes box on the configuration view.

Setup in Obj C

1. Add in AppDelegate.h file

    #import <Google/SignIn.h> 
   

2. In Appdelegate.m file add the following lines of code . Replace YOUR_CLIENT_ID with your CLIENT_ID from credentials.plist file.

    - (BOOL)application:(UIApplication *)application
    didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // Initialize Google sign-in.
    
    #warning relpace the string with your CLIENT_ID from credentials.plist
    [GIDSignIn sharedInstance].clientID = @"<YOUR_CLIENT_ID>";
    
    return YES;
    }
    
    - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation {
    return [[GIDSignIn sharedInstance] handleURL:url sourceApplication:sourceApplication annotation:annotation];
    }
   

3. in your desired class in .h file add following code

      #import "SDGDTableViewController.h"
   

Implement the
SDGDTableViewControllerDelegate Once implemented, you'll recieve calls when a file is downloaded or fails to download or progressValue. Like

      @interface YourClassName : UIViewController <SDGDTableViewControllerDelegate>

4. in your desired class in .m file add this line of code

   UIStoryboard* storyboard = [UIStoryboard storyboardWithName:@"SDGD"
                                                    bundle:nil];
   SDGDTableViewController *obj=
       [storyboard instantiateViewControllerWithIdentifier:@"SDGDTableViewController"];
   
   obj.delegate = self;
   UINavigationController *nav = [[UINavigationController alloc]initWithRootViewController:obj];
   [self presentViewController:nav animated:YES completion:nil];
   

Setup in Swift

Follow the Steps in Google Configuration (Both Objective C and Swift)

1. Add the following line into your into your Bridging header file

   #import  <GoogleDriveBrowser/SDGDTableViewController.h>
   

2. Add the following line into your into your AppDelegate.swift file

   import Google
   

3. Add the following line into your into your applicationDidFinishLaunching function in AppDelegate.swift file .Replace YOUR_CLIENT_ID with your CLIENT_ID from credentials.plist file.

   GIDSignIn.sharedInstance().clientID = "<YOUR_CLIENT_ID>"
   

4. Add the following functions into your into your AppDelegate.swift file

   func application(_ application: UIApplication, open url: URL, sourceApplication: String?, annotation: Any) -> Bool {
   return GIDSignIn.sharedInstance().handle(url,
                                           sourceApplication: sourceApplication,
                                           annotation: annotation)
   }
   
   @available(iOS 9.0, *)
   func application(_ app: UIApplication, open url: URL,
               options: [UIApplicationOpenURLOptionsKey : Any]) -> Bool {
   let sourceApplication = options[UIApplicationOpenURLOptionsKey.sourceApplication] as? String
   let annotation = options[UIApplicationOpenURLOptionsKey.annotation]
   return GIDSignIn.sharedInstance().handle(url,
                                           sourceApplication: sourceApplication,
                                           annotation: annotation)
   

}

5. Add the following lines of code In your desired class

   var  obj = SDGDTableViewController() ;
   let storyboard : UIStoryboard = UIStoryboard(name: "SDGD", bundle: nil)
   obj = storyboard.instantiateViewController(withIdentifier: "SDGDTableViewController") as! SDGDTableViewController
   obj.delegate = self
   let nav = UINavigationController.init(rootViewController: obj)
   self.present(nav, animated: true, completion: {
   })
   

By Default library image will load on google file view . You may change those images
