Category “IKImageBrowserItem” on NSObject.

The IKImageBrowserItem informal protocol declares the methods that an instance of IKImageBrowserView uses to access the contents of its data source for a given item.

Some of the methods in this protocol, such as image are called very frequently, so they must be efficient.

Provided Methods

unsafe fn imageUID(&self) -> Option<Retained<NSString>>

Returns a unique string that identify this data source item (required).

The image browser uses this identifier to keep the correspondance between its cache and the data source item

unsafe fn imageRepresentationType(&self) -> Option<Retained<NSString>>

Returns the representation of the image to display (required).

Keys for imageRepresentationType are defined below.

unsafe fn imageRepresentation(&self) -> Option<Retained<AnyObject>>

Returns the image to display (required). Can return nil if the item has no image to display.

unsafe fn imageVersion(&self) -> NSUInteger

Returns a version of this item. The receiver can return a new version to let the image browser knows that it shouldn’t use its cache for this item

unsafe fn imageTitle(&self) -> Option<Retained<NSString>>

Returns the title to display as a NSString. Use setValue:forKey: with IKImageBrowserCellsTitleAttributesKey on the IKImageBrowserView instance to set text attributes.

unsafe fn imageSubtitle(&self) -> Option<Retained<NSString>>

Returns the subtitle to display as a NSString. Use setValue:forKey: with IKImageBrowserCellsSubtitleAttributesKey on the IKImageBrowserView instance to set text attributes.

unsafe fn isSelectable(&self) -> bool

Returns whether this item is selectable.

The receiver can implement this methods to forbid selection of this item by returning NO.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
