Remarks
Xamarin.iOS will export any interfaces with this attribute as a protocol to Objective-C, and any classes that implement these interfaces will be marked as implementing the corresponding protocol when exported to Objective-C.
// This will create an Objective-C protocol called 'IMyProtocol', with one required member ('requiredMethod')
[Protocol ("IMyProtocol")]
interface IMyProtocol
{
[Export ("requiredMethod")]
void RequiredMethod ();
}
// This will export the equivalent of "@interface MyClass : NSObject <IMyProtocol>" to Objective-C.
class MyClass : NSObject, IMyProtocol
{
void RequiredMethod ()
{
}
}
