PSPDFFlexibleToolbar

Objective-C


@interface PSPDFFlexibleToolbar : PSPDFToolbar

Swift

class FlexibleToolbar : Toolbar

A custom toolbar, that can be dragged around the screen and anchored to different positions.

This class holds an array of UIButton objects. For best results use PSPDFToolbarButton or one of its subclasses. PSPDFFlexibleToolbar should be used in combination with a PSPDFFlexibleToolbarContainer instance. The bar’s visual appearance can be customized using UIAppearance compliant properties.

See

PSPDFFlexibleToolbarContainer

  • A list of valid toolbar positions.

    Defaults to PSPDFFlexibleToolbarPositionDefault on iOS and PSPDFFlexibleToolbarPositionInTopBar on Mac Catalyst.

    @note: Change this before setting toolbarPosition, else any unsupported toolbarPosition is rejected.

    Declaration

    Objective-C

    @property (nonatomic) PSPDFFlexibleToolbarPosition supportedToolbarPositions;

    Swift

    var supportedToolbarPositions: FlexibleToolbar.Position { get set }

  • Current toolbar position.

    See

    setToolbarPosition:animated:

    Note

    Ensure that any new toolbar position is supported in supportedToolbarPositions, else the value is rejected.

    Objective-C

    @property (nonatomic) PSPDFFlexibleToolbarPosition toolbarPosition;

    Swift

    var toolbarPosition: FlexibleToolbar.Position { get set }

  • Sets the toolbar position and optionally animates the change

    When PSPDFFlexibleToolbarPositionNone is used (the default value) the toolbar can select an appropriate default position or restore position from previous runs.

    Parameters

    toolbarPosition

    The new toolbar position to set. Limited to supportedToolbarPositions.

    @property (nonatomic, readonly) PSPDFFlexibleToolbarDragView *_Nonnull dragView;

    Swift

    var dragView: PSPDFFlexibleToolbarDragView { get }

    (nonnull UIView<PSPDFSystemBar> *)navigationBarOrToolbar;

  • Returns the toolbars native size for the provided position, bound to the availableSize. Internally used by the container view to correctly position the toolbar and anchor views during drag & drop. The toolbar height will be increased when docked underneath the status bar by PSPDFFlexibleToolbarContainer.
