UITableViewSource Class

Definition

Joint UITableViewDataSource and UITableViewDelegate base class. Preferred way to provide data and handle lifecycle events for UITableViews.

[Foundation.Register("UITableViewSource", false)]
public abstract class UITableViewSource : UIKit.UIScrollViewDelegate
type UITableViewSource = class
    inherit UIScrollViewDelegate
Inheritance
Derived
Attributes

Remarks

UITableViewSource merges both the UITableViewDataSource and the UITableViewDelegate into a single class. It is more cohesive than subclassing those independently, but there is no technical barrier to application developers working with those types directly.

Application developers must subtype this class, override the methods as necessary, and assign an instance of this object to the Source property.

The methods merged from UITableViewDataSource provide the table view with all the information it requires to display its data - such as informing it of the number of sections and rows, and what cell view to use for each row. The methods merged from UITableViewDelegate provide the table view with the ability to manage selection, configure section headers and footers, delete and reorder cells and control the editing menu.

Constructors

UITableViewSource()

Default constructor that initializes a new instance of this class with no parameters.

UITableViewSource(IntPtr)

A constructor used when creating managed representations of unmanaged objects; Called by the runtime.

UITableViewSource(NSObjectFlag)
