Instance Method

initWithBase64EncodedData:options:

Initializes a data object with the given Base64 encoded data.

Declaration

- (instancetype)initWithBase64EncodedData:(NSData *)base64Data options:(NSDataBase64DecodingOptions)options;

Parameters

base64Data

A Base64, UTF-8 encoded data object.

options

A mask that specifies options for Base64 decoding the data. Possible values are given in NSDataBase64DecodingOptions.

Return Value

A data object containing the Base64 decoded data. 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 NSDataBase64DecodingIgnoreUnknownCharacters.
