Returns a data object initialized with the given Base-64 encoded string.

Declaration

init?(base64Encoded base64String: String, options: NSData.Base64DecodingOptions = [])

Parameters

base64String

A Base-64 encoded string.

options

A mask that specifies options for Base-64 decoding the data. Possible values are given in NSData.Base64Decoding​Options.

Return Value

A data object built by Base-64 decoding the provided string. Returns nil if the data object could not be decoded.

Discussion

The default implementation of this method will reject non-alphabet characters, including line break characters. To support different encodings and ignore non-alphabet characters, specify an options value of ignore​Unknown​Characters.
