Simple IOS Project about loading music to simulator

IOS-Pratice-MusicLover

This project finishing the basic IOS Tutorial.

The Music Model:

Properties:

• var name: String
• var photo: UIImage?
• var rating: Int
• var animatedImage: FLAnimatedImage?
• var photoURLString: String?
• var isGif: Bool = false

In my local file and web server file:

Properties:

• var name: String
• var rating: Int
• var photoURLString: String?

Other properties in Music Model, we could using function in the music model to get them

Implementing the bellow requirements:

1. Basic Tutorial,(Using TableView to arrange the objects, implement the ranking method)

• Using SDWebImageManager() to manage the image
• Using UIStackView to actualize the RatingControl

2. Not only for static image, implement to load/download the "gif" dynamic image.

• Change the photoImageView to FLAnimatedImageView to actualize display the animated image
• FLAnimatedImageView using

3. Implement store data into local file(music.json)

• In MusicTableViewController.loadMusics() function
• Using JSONEncoder and JSONDecoder to encode and decode JSON data
• The File path achieved by
• • static let DocumentsDirectory = FileManager().urls(for: .documentDirectory, in: .userDomainMask).first!
• • static let ArchiveURL = DocumentsDirectory.appendingPathComponent("musics.json")

4. Implement store data into web server(http://127.0.0.1:8000/musics/)

• Using Django Rest Framework to implement the web local server
• In Django/ Folder, is the implement of this server. It's using python language to implement.
• In MusicTableViewController.getDataFromMockServer() and MusicTableViewController.postDataToMockServer(), achieve the GET method and POST method
• Attention: don't forget using DispatchQueue.main.async() to asynchronous the self.tableView.reloadData(). This make sure there is something shows in our simulator

Run:

1. install cocoapod, go to the project folder, run "pod install"

2. start the server, do bellow comands in terminal

   install python and virtualenv

   Go to Django folder

   virtual -p /usr/local/bin/python3 venv

   source venv/bin/activate

   pip install Django

   sudo easy_install pip

   touch requirements.txt

   pip freeze > requirements.txt

   django-admin startproject config

   pip install djangorestframework

   go to /config/config/settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', # Ensure a comma ends this line 'rest_framework', # Add this line ]

   cd into the folder where manage.py file is, python3 manage.py startapp api INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'rest_framework', 'api', # Add this line ]

   I have already finishing the model, view, and url part, if don't change it, go! cd into the manage.py file,

   python3 manage.py makemigrations

   python3 manage,py migrate

   without error, run the server!

   python3 manage.py runserver

3. After setting the server, run the project in MusicLover.xcworkspace

4. Could Add/Delete/Save object, for web server, could check it through open the url link(http://127.0.0.1:8000/musics/), for local server, uncommand the line under "load data local", and command the line under "load data by url server"
