Instance Property


The type of the target file.


@property(nonatomic, copy) NSString *UTI;


The value of this property is used to determine which apps are capable of opening the document. The default value is determined automatically whenever possible. However, if the document is a custom type that cannot be determined readily, the value of this property may be nil. If you know the type of the document, you can set the value of this property explicitly.
