Time for action – connecting the App Delegate to the GUI


Since we have already created the .xib file, we just need to add the reference in to our App Delegate and then connect them to our GUI.

  1. In Xcode, click on the file named BTSAppDelegate.h in the project navigator and add the following properties:

    /* 
        Define the GUI elements
     */
    
    @property (assign) IBOutlet NSTextField *mLastUpdateTimeTextField;
    @property (assign) IBOutlet NSProgressIndicator *mLastUpdateTimeProgressIndicator;
    @property (assign) IBOutlet NSTextField *mValueToConvertTextField;
    @property (assign) IBOutlet NSPopUpButton *mCurrencyToConvertPopUp;
    @property (assign) IBOutlet NSTableView *mConvertedCurrencyTableView;

    Note

    Note that the outlets are declared as assign rather than weak. Typically under Automatic Reference Counting (ARC) they would be weak (since they are owned by their super view) but we can also declare them assign if we want to be compatible with earlier OS versions that don't support ARC.
