Flags a class or interface as a model, indicating that only explicitly overridden methods are exposed to the Objective-C runtime.

[System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface)]
public sealed class ModelAttribute : Attribute

[<System.AttributeUsage(System.AttributeTargets.Class | System.AttributeTargets.Interface)>]
type ModelAttribute = class
    inherit Attribute

Inheritance: Attribute

Attributes: AttributeUsageAttribute

Remarks

Objective-C protocols are like interfaces, but they support optional methods, that is, not all of the methods need to be implemented for the protocol to work.

The [Model] attribute is applied to a class that can have optional methods, and it is typically used for declaring Objective-C delegates or data models that have a number of optional methods. The runtime treats classes with the Model attribute applied specially: only when a user overrides methods in a class is the actual override exposed to the Objective-C world as existing.

This attribute is used in all of the models and delegate classes to allow the user to only implement the methods that they are interested in.
