Time-Tracker

An iOS app with time tracking

###Step 1: Create the list view controller

• Either in Pomodoro or in a new app create a new ListViewController (list of Project instances)
• Add it to the window's rootViewController inside of a navigation controller

###Step 2: Setting up a tableViewDatasource

• Create a new datasource object (ListTableViewDatasource subclass of NSObject)
• Add the UITableViewDatasource protocol required methods
• Add a dataSource property to your list viewcontroller (strong)
• Initialize the dataSource in the init method
• Add a tableView property to ListViewController
• Initialize the tableView and add it to the viewcontroller's view
• Set the datasource of tableView to your dataSource property

###Step 3: Create a model and model controller See "Entries" for a sample project

• Create a Project class with necessary properties

  • Each Project instance should hold an array of ```Entries``
  • You'll need an AddEntry: and RemoveEntry: method

• Create an Entry (word periods) class with necessary properties

• Create a ProjectController singleton class (add the instancetype method)

  • The ProjectController should hold an array of Project instances
  • You'll need an AddProject: and RemoveProject: method

• You'll need methods that convert the objects (Project and Entry) to and from dictionaries

  • (This allows you to store the model in NSUserDefaults)
  • Don't forget to implement storing of Projects to NSUserDefaults (loadFromDefaults, syncronize) -Look back at "Day-X" for example

• Now you can use the ProjectController for the row count and row value for the tableView

  • Use the title Property of Project for the cell label

###Step 4: Add a DetailViewController (Project instance detail)

• Create a DetailViewController with an XIB file
• Add a titleTextField for the title
• Add a timeLabel to show the total time
• Add a tableView to show the list of Entries
• Add a UIToolBar with an Add, Check In, Check Out, and Report button
• Add those objects as properties on the view
  • Wire them up
• Add a method for each button
  • Add
  • Clock In
  • Clock Out
  • Report

###Step 5: Add UITextFieldDelegate methods to capture the title

• Add the textFieldShould return method to dismiss the Keyboard
• Add a textFieldShouldEndEditing method to store the text of the titleTextField as the project.title
• Wire files owner as the delegate of the text field in the XIB file

###Step 6: Add a datasource for the tableview

• Create a new datasource object (DetailTableViewDatasource subclass of NSObject)
• Add the UITableViewDataSource protocol required methods
• Add a dataSource property to your DetailViewController (strong)
• Initialize the dataSource in the init method
• Set the self.tableView.dataSource to your dataSource property

###Step 7: Show a list of entries

• Add a public Project property to the DetailViewController
• In the didSelectRow method in the ListViewController set the DetailViewController's Project property as the project in the ProjectController's project list at the index selected
• Add a public Project property to the DetailTableViewDatasource
• In the viewDidLoad method of the DetailViewController set the dataSource's project property to self.property
• NumberOfRows should be equal to number of entries
• Set the cell's textLabel.text to the entry's start and end date
  • Feel free to format them if you'd like it to look pretty: http://gtiapps.com/?p=1086

###Step 8: Add a Clock In and Clock Out method to the Project object

• Add a method startNewEntry
  • In that method create a new Entry, and set the start time to now
  • Store that entry as a currentEntry private property of Project
• Add a method endCurrentEntry
  • In that method set the end time of currentEntry to now
• Call those methods when the user selects clockIn or clockOut BarButtonItems on your UIToolBar
  • Be sure to reload the tableView's data

###Step 9: Create a custom entry screen

• Create a new CustomEntryViewController with an XIB file
• Add a public Project property to your CustomEntryViewController
• Add a fake navigation bar
  • Add a cancel and save button and a title
• Wire up the cancel and save buttons to IBActions cancel and save
• Add date pickers and title labels
  • Add two date pickers and wire them up to startDatePicker and endDatePicker IBOutlet properties
  • Add two labels startDateLabel and endDateLabel above the pickers to show which is which (they don't need to be wired)
• In the save method create a new Entry and set the start and end times from the picker views
• In both the save and cancel method call "dismissViewController"
• In the add method of the DetailViewController, instantiate a CustomEntryViewController, set the project property, and call "presentViewController" to show it

###Step 10: Add reporting

• Add the MessageUI library to your project
• In the report method, instantiate an MFMailComposeViewController
• Create a string of all of the entry times (loop through the entries and append the times to the string)
• Set the message string as the messageBody of the viewController
• Call presentViewController on the mailComposeViewController
