Declaration

func addingPercentEscapes(using enc: UInt) -> String?

Parameters

  • enc:

    The encoding to use for the returned string. If you are uncertain of the correct encoding you should use Nsutf8stringencoding.

Return Value

A representation of the receiver using encoding to determine the percent escapes necessary to convert the receiver into a legal URL string. Returns nil if encoding cannot encode a particular character.

Discussion

It may be difficult to use this function to “clean up” unescaped or partially escaped URL strings where sequences are unpredictable. See CFURLCreateStringByAddingPercentEscapes(_:_:_:_:_:) for more information.
