Instance Property

creationDate

A value that indicates the creation date of the asset.

Declaration

@property(nonatomic, readonly) AVMetadataItem *creationDate;

Discussion

The value of this property may be nil.

If a creation date has been stored by the asset in a form that can be converted to an NSDate object, the dateValue property of the metadata item provides an instance of NSDate. Otherwise the creation date is available only as a string value, using the AVMetadataItem class’s stringValue method.
