Glasgow Reference DataBasedViewController Class Reference

DataBasedViewController

open class DataBasedViewController : UIViewController

Provides a basic ViewController capable of perform data synchronization operations.

Properties

courtainView
A view to be displayed as a courting, covering entire view, when fetching data.
Declaration
Swift

@IBOutlet open weak var courtainView: UIView?

Initialization


                    
                    
                    viewWillAppear(_:)

Prepares the ViewController to become visible. Checks if any data operation must be executed.

Declaration

Swift

override open func viewWillAppear(_ animated: Bool)

Parameters


                                animated

If presentation must use animation to become visible

Data Syncrhonization

performDataSync()
Performs data synchronization if shouldSyncData() validates.

During data synchornization, willSyncData(), then syncData() and finally didSyncData() will be called.

If not data synchronization is performed, only didSyncData() is called.
Declaration
Swift

@objc open func performDataSync()
showCourtainView()
If courtainView is defined, makes it visible.
Declaration
Swift

open func showCourtainView()
hideCourtainView()
If courtainView is defined, hides it.
Declaration
Swift

open func hideCourtainView()

Child classes are expected to override these methods

shouldSyncData()
Validates if data synchronization must be executed.

By default, returns always true.
Declaration
Swift

open func shouldSyncData() -> Bool
willSyncData()
Data synchronization will be executed.

By default, executed showCourtainView()
Declaration
Swift

open func willSyncData()
syncData()
Executes data synchronization.

This method is intended to be overriden by child ViewControllers in order to implement proper data synchronization.

By default, does nothing.
Declaration
Swift

open func syncData()
didSyncData()
Data synchronization was completed.

By default, executes hideCourtainView()
Declaration
Swift

open func didSyncData()
