Contacts App

This App is made as an homework.

[gif][] It is made to accommodate the requirements of one homework. So it didn't use some regulations of iOS development, also this tutorial is a reminder for myself.

It is largely learned from Apple Start Developing iOS Apps(Swift)

Person.swift

This class is used to store the contact.

PersonViewController.swift

This is the controller to control person view. that is the page to add and edit contact.

Partically notice I used datePicker as an input textBox and set the maximum date to today.

Learned from :

change-textfield-input-to-datepicker

Also notice I changed the keypad style of different TextField, disable auto correct.

PersonTableViewCell.swift

This is used to define a custom cell.

PersonTableViewController.swift

Several interesting function to notice:

• sort : This will make the people list sorted by first name, this is similar to C++ reload function, this is very concise and beautiful.

	 // sort list 
	 func sortList() {
	     people.sortInPlace() { $0.fname < $1.fname } // sort the people by name
	     tableView.reloadData(); // notify the table view the data has changed
	 }
    

Learned from here : How we can sort(ascending and descending) a uitableview data in swift language

• swipe to delete but with confirmation : just use swipe to delete is kind of too sloppily, while I don't know how to imitate the real contacts app, seems a lot of delegate or sth.

Learned from here : swipe to delete with confirmation

And I do have a lot of unclear parts in this file. I didn't quite understand some code at this point, the segue is just imitate the Apple Document.

FileOp.swift

This is very ugly code|||. Hope someday can improve it.
