• Moving view to prevent keyboard/picker obscuring a field: An observer in ViewDidLoad allows the controller to tell when a keyboard/picker is open and calls a function to move the view 65px upwards, to prevent the input field from being obscured.

let nc = NotificationCenter.default
//Observers to determine keyboard state and move view so that fields aren't obscured
nc.addObserver(self, selector: #selector(keyboardWillShow(sender:)), name: NSNotification.Name.UIKeyboardWillShow, object: nil)
nc.addObserver(self, selector: #selector(keyboardWillHide(sender:)), name: NSNotification.Name.UIKeyboardWillHide, object: nil)

Table

• Setting cell labels: ViewControllerExercise.tableView(_:cellForRowAt:) uses fetched objects to set the labels of the table cells

• Displaying exercise logs for current day shown on graph: An observer is used to watch for notifications from ViewControllerGraph and update the class’ currentDay property. The data for the table is then fetched again for exercise logs which match currentDay
  

//Observer to update currentDay variable to match graph's day
nc.addObserver(self, selector: #selector(updateDay(notification:)), name: Notification.Name("dayChanged"), object: nil)

Instantiation of observer for when day displayed on the graph changes

Favouriting System

• Favouriting: If a user clicks the star of an exercise log’s cell it will highlight in the colour of the domain, to symbolise it has been favourited. This will call a function to add the exercise to the Favourites object’s relationships.
• Choosing from favourites: When the star in the data entry section is selected, it will highlight in the colour of the domain. The table will update to display exercise logs which are favourited instead of the displayed day’s exercise logs. If a user selects one of these cells, it will automatically fill in the text fields with that exercise log’s information and the current time. The user can then adjust or add this exercise, as normal.

Future Work

• Add status indicators to show next planned exercise or other useful information.
• Add expanding cells and buttons to edit or remove an exercise log from the database in the table.
