Instance Property

allowedTypes

Sets the component types allowed in the path when the cell is editable.

Declaration

@property(copy) NSArray<NSString *> *allowedTypes;

Parameters

allowedTypes

An array of strings representing either file extensions or UTIs. Can be nil, the default value, allowing all types.

Discussion

The allowedTypes array can contain file extensions (without the period that begins the extension) or UTIs. To allow folders, include the public.folder identifier. To allow any type, use nil. If the value of allowedTypes is an empty array, nothing is allowed. The default value is nil, allowing all types.

If the cell is editable and its type is NSPathStylePopUp, a Choose item is included to enable selection of a different path by invoking an Open panel. The allowed types are passed to the Open panel to filter out other types. The allowed types are also used with drag and drop to indicate if a drop is allowed.
