There is no cancel action in Media Picker Controller.
If I make a wrong select, I cannot undo.
I want a cancel button in Media Picker Controller.
There is a cancel button when making a playlist in Apple Original Music Application.
Is it possible to add a cancel action to Media Picker Controller?
I find this in documentation
Instance Method mediaPickerDidCancel(_:)
Called when a user dismisses a media item picker by tapping Cancel.
Declaration
optional func mediaPickerDidCancel(_ mediaPicker: MPMediaPickerController)Parameters
mediaPickerThe media item picker to dismiss.
So there should be a cancel button. Probably it is just not visible.

When you have made it possible to select multiple songs, MediaPickerController just has a button to the right of the toolbar that says “Completed.”
If you press this button without selecting any songs, mediaPickerDidCancel (_:) will be called.
However, when one or more songs are selected, pressing this button calls mediaPicker (_:).
In other words, if you select even one song, there is no way to call mediaPickerDidCancel (_:).
I want to display both the Finish and Cancel buttons on the toolbar.
What about unselecting the selected songs ? That should revert to the cancel behavior.
I am in trouble because I can not unselect the selected song.
Did you set allowsPickingMultipleItems to false ?
Instance Property allowsPickingMultipleItems
A Boolean value specifying the default selection behavior for a media item picker.
Declaration
var allowsPickingMultipleItems: Bool { get set }Discussion
When set to
truefalsefalsetrueSince I want to be able to select multiple songs, it is true. To make it false and to make a single choice is not what I think.
I want a Cancel button with multiple songs available for selection.
Understood, but API spec seems to show this is not possible, unless you write your own picker subclass.
