PTTabbedDocumentViewControllerDelegate

@protocol PTTabbedDocumentViewControllerDelegate <NSObject>

The methods declared by the PTTabbedDocumentViewControllerDelegate protocol allow the adopting delegate to respond to messages from the PTTabbedDocumentViewController class.


                    
                    
                    -tabbedDocumentViewController:createViewControllerForDocumentAtURL:

This method is called when the tabbed document view controller is opening the document at the specified URL and needs to create a new document view controller for the tab. The delegate must create and return a new instance of a PTDocumentBaseViewController subclass.

If this method is not implemented by the delegate, an instance of the class specified by the PTTabbedDocumentViewController.viewControllerClass will be created.

Declaration

Objective-C

- (nonnull __kindof PTDocumentBaseViewController *)
            tabbedDocumentViewController:
                (nonnull PTTabbedDocumentViewController *)
                    tabbedDocumentViewController
    createViewControllerForDocumentAtURL:(nonnull NSURL *)url;

Swift

optional func tabbedDocumentViewController(_ tabbedDocumentViewController: PTTabbedDocumentViewController, createViewControllerForDocumentAt url: URL) -> PTDocumentBaseViewController


                    
                    
                    -tabbedDocumentViewController:willAddDocumentViewController:

Informs the delegate that a document view controller will be added. This provides an opportunity to perform any setup on the view controller before it is presented to the user.

Declaration

Objective-C

- (void)
     tabbedDocumentViewController:
         (nonnull PTTabbedDocumentViewController *)tabbedDocumentViewController
    willAddDocumentViewController:
        (nonnull __kindof PTDocumentBaseViewController *)documentViewController;

Swift

optional func tabbedDocumentViewController(_ tabbedDocumentViewController: PTTabbedDocumentViewController, willAddDocumentViewController documentViewController: PTDocumentBaseViewController)


                    
                    
                    -tabbedDocumentViewController:willRemoveTabAtIndex:

Informs the delegate that a tab will be removed from the tabbed document view controller.

Declaration

Objective-C

- (void)tabbedDocumentViewController:(nonnull PTTabbedDocumentViewController *)
                                         tabbedDocumentViewController
                willRemoveTabAtIndex:(NSUInteger)index;

Swift

optional func tabbedDocumentViewController(_ tabbedDocumentViewController: PTTabbedDocumentViewController, willRemoveTabAt index: UInt)


                    
                    
                    -tabbedDocumentViewController:didRemoveTab:atIndex:

Informs the delegate that a tab has been removed.

Declaration

Objective-C

- (void)tabbedDocumentViewController:(nonnull PTTabbedDocumentViewController *)
                                         tabbedDocumentViewController
                        didRemoveTab:(nonnull PTDocumentTabItem *)tab
                             atIndex:(NSUInteger)index;

Swift

optional func tabbedDocumentViewController(_ tabbedDocumentViewController: PTTabbedDocumentViewController, didRemoveTab tab: PTDocumentTabItem, at index: UInt)

Parameters

`tabbedDocumentViewController`	The tabbed document view controller.
`tab`	The tab object that was removed.
`index`	The index of the tab.


                    
                    
                    -tabbedDocumentViewController:shouldHideTabBarForTraitCollection:

This method allows the delegate to decide if the tab bar should be hidden for the given trait collection.

If this method is not implemented, the tab bar will be hidden for compact horizontal size classes.

Declaration

Objective-C

- (BOOL)tabbedDocumentViewController:(nonnull PTTabbedDocumentViewController *)
                                         tabbedDocumentViewController
    shouldHideTabBarForTraitCollection:
        (nonnull UITraitCollection *)traitCollection;

Swift

optional func tabbedDocumentViewController(_ tabbedDocumentViewController: PTTabbedDocumentViewController, shouldHideTabBarFor traitCollection: UITraitCollection) -> Bool
