public static System.Threading.Tasks.Task<Photos.PHAuthorizationStatus> RequestAuthorizationAsync ();static member RequestAuthorizationAsync : unit -> System.Threading.Tasks.Task<Photos.PHAuthorizationStatus>Returns
A task that represents the asynchronous RequestAuthorization operation. The value of the TResult parameter is of type System.Action<Photos.PHAuthorizationStatus>.
Remarks
The RequestAuthorizationAsync method is suitable to be used with C# async by returning control to the caller with a Task representing the operation.
The handler is called with the new PHAuthorizationStatus. Note that the handler is likely to be called on a background thread and updates to the user interface must be done with InvokeOnMainThread(Selector, NSObject).
