In this lesson, we will register as a new Parse developer and add our app to Parse.

We download the Parse framework then add the it to our project. We will also add all the required dependencies.

We test the Parse framework by saving few objects into the cloud.

We learn how to write a basic query to get objects from Parse cloud. Then we display the result with a table view

We learn to use the table view controller called PFQueryTableViewController from Parse to automatically retrieve and display objects from Parse cloud.

We create basic login and sign up controllers and their views. We also connect all the necessary IBActions and IBOutlets.

Learn how to sign up and login new users with Parse

In this video, we sign up as a new Facebook developer and register our app with Facebook.

We learn how to integrate Facebook Login with Parse login. We will be using a login view controller called PFLoginViewController to achieve this.

In this lesson, we implement the necessary login view controller delegate methods for the login to work

We use facebook API to retrieve user information from Facebook and then save the information to Parse

We create a camera view controller and add UIImagePickerViewController for obtaining images from camera or photo library.

We setup photo upload screen in Storyboard where the user can add a title and preview the photo.

We will implement the image picker delegate methods that are responsible for the scenarios when the user has successfully taken a photo and when the user has cancelled taking a photo.

In this lesson, we write the code for wrapping the image data into a PFFile object, a file object provided by Parse, then upload the file to Parse cloud.

In this lesson, we will create the views for section header cell and photo cell inside storyboard

There are a lot of datasource and delegate methods waiting to be implemented. A template file is provided here with all the methods we are going to talk about in the next few lessons.

We are going to implement the section header cell for displaying user profile image, username, image title, and follw button.

We are going to implement the photo cell for displaying large photos from Parse.

Due to the complexity of our app, we can no longer rely on PFQueryTableViewController for automatically retrieving data for us. We need to write a custom query to the photos along with their corresponding user profile information.

Due to the way we display our photos in sections rather than rows, the pagination feature is broken. In this lesson, we will fix this issue.

In order for our users to follow each other, we need to add a new Activity class to store the relationship information among users. In this lesson we will look at what key value pairs we need to store inside Activity class.

We will create a custom follow button, a subclass of UIButton, for follow/unfollow other users.

We will implement the follow button delegate method inside home view controller. We will create queries for adding and removing relationships from the Activity class

The follow button must be updated dynamically to reflect the changes when user follow or unfollow another user. We will write a query to get the current state of the database and update the follow buttons accordingly.

The profile view is very similar to the home view controller we implemented in the previous section. We can reuse the code we wrote for home view controller when building the profile view controller

The biggest addition inside profile view is the user status view. In this lesson, we create several queries for retrieving the user status information from Parse.

The profile screen contains a timeline just like the home screen. However, this timeline will only display the photos from the current user and the people the current user is following. We will write a query to obtain these photos.

We have finished coding all the logic behind the app. In this lesson, we will start to apply the UI design and polish our app. First, we need to import all the icons into our project.

In this lesson, we add fonts, colors and icons to the login screen.

In this lesson, we add fonts, colors and icons to the home screen.

In this lesson, we add fonts, colors and icons to the camera screen.

In this lesson, we add fonts, colors and icons to the profile screen.

In this lesson, we will change the color of the status bar to white and add tab bar icons to the tab bar
