ParseUI is a set of user interface components built on top of the Parse framework, which simplifies the process of creating beautiful and functional apps. With ParseUI, you can effortlessly integrate user authentication, data storage, and other features into your iOS or Android applications. This documentation aims to provide you with comprehensive guidance and examples on how to make the most of ParseUI.
## Installation
To start using ParseUI, you must first install it in your project. Follow the steps below to get started:
1. Open your project in Xcode or Android Studio.
2. Ensure that you have installed the Parse framework ([official Parse framework documentation](https://docs.parseplatform.org/ios/guide/)).
3. Add the ParseUI library to your project by including it in your Podfile (iOS) or Gradle file (Android).
“`
// For iOS:
pod ‘ParseUI’
// For Android:
implementation ‘com.parse:parseui:latest-version’
“`
4. Run the appropriate command to update your project dependencies. For iOS, use `pod install`. For Android, click on the “Sync Now” prompt.
## Authentication
ParseUI simplifies the process of authenticating users in your app, allowing you to focus on creating a delightful user experience. This section details the authentication options available within ParseUI:
### Logging In
To enable user login functionality, follow these steps:
1. Import the necessary classes in your file:
“`swift
import Parse
import ParseUI
“`
2. Set up a login view controller by subclassing `PFLogInViewController` and implementing the appropriate delegate methods. For example:
“`swift
class CustomLogInViewController: PFLogInViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Customize the login view here
}
}
“`
3. Present the login view controller to the user when required. For example:
“`swift
let loginController = CustomLogInViewController()
self.present(loginController, animated: true, completion: nil)
“`
### Signing Up
To allow users to sign up for your app, follow these steps:
1. Import the necessary classes in your file:
“`swift
import Parse
import ParseUI
“`
2. Set up a sign-up view controller by subclassing `PFSignUpViewController` and implementing the appropriate delegate methods. For example:
“`swift
class CustomSignUpViewController: PFSignUpViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Customize the signup view here
}
}
“`
3. Present the sign-up view controller to the user when required. For example:
“`swift
let signUpController = CustomSignUpViewController()
self.present(signUpController, animated: true, completion: nil)
“`
### User Management
ParseUI provides several methods to manage user accounts efficiently. Here are some common functionalities:
1. Retrieving the current user:
“`swift
if let user = PFUser.current() {
// Do something with the user
}
“`
2. Logging out the current user:
“`swift
PFUser.logOutInBackground { (error: Error?) in
if error == nil {
// User successfully logged out
} else {
// An error occurred while logging out
}
}
“`
3. Resetting a forgotten password:
“`swift
PFUser.requestPasswordResetForEmail(inBackground: “user@example.com”) { (success: Bool, error: Error?) in
if success {
// Password reset email sent successfully
} else {
// An error occurred while sending the password reset email
}
}
“`
Remember to handle errors appropriately when implementing user management tasks.
## Data Storage
ParseUI simplifies data storage by providing intuitive user interface components. Here are the options available for data storage:
### Object Querying
To query object data from Parse, you can use the provided `PFQueryTableViewController`:
1. Import the necessary classes in your file:
“`swift
import Parse
import ParseUI
“`
2. Create a subclass of `PFQueryTableViewController`:
“`swift
class CustomQueryTableViewController: PFQueryTableViewController {
override func queryForTable() -> PFQuery
// Return your custom query for object retrieval
}
}
“`
3. Customize the table view appearance if needed using delegate methods.
### Object Creation
To create new objects and save them to Parse, follow these steps:
1. Import the necessary classes in your file:
“`swift
import Parse
import ParseUI
“`
2. Set up an object creation view controller by subclassing `PFSignUpViewController` and implementing the appropriate delegate methods. For example:
“`swift
class CustomObjectCreationViewController: PFSignUpViewController {
override func viewDidLoad() {
super.viewDidLoad()
// Customize the object creation view here
}
}
“`
3. Present the object creation view controller to the user when required. For example:
“`swift
let objectCreationController = CustomObjectCreationViewController()
self.present(objectCreationController, animated: true, completion: nil)
“`
## Other Features
ParseUI offers additional features to enhance your app:
### Push Notifications
To enable push notifications using ParseUI, follow these steps:
1. Set up push notifications for your app by following the official [Parse push notifications documentation](https://docs.parseplatform.org/ios/guide/#push-notifications).
2. Customize push notifications appearance with the provided classes from ParseUI.
### Cloud Functions
ParseUI allows you to call cloud functions effortlessly for server-side processing. To utilize cloud functions, follow these steps:
1. Import the necessary classes in your file:
“`swift
import Parse
import ParseUI
“`
2. Invoke a cloud function with the desired parameters. For example:
“`swift
PFCloud.callFunction(inBackground: “myFunction”, withParameters: [“key”: value]) { (result: Any?, error: Error?) in
if error == nil {
// Function executed successfully
} else {
// An error occurred while executing the function
}
}
“`
