Returns a percent-escaped string following RFC 3986 for a query string key or value. RFC 3986 states that the following characters are “reserved” characters.
- General Delimiters: “:”, “#”, “[”, “]”, “@”, “?”, “/”
- Sub-Delimiters: “!”, “$”, “&”, “‘”, “(”, “)”, “*”, “+”, “,”, “;”, “=”
In RFC 3986 - Section 3.4, it states that the “?” and “/” characters should not be escaped to allow query strings to include a URL. Therefore, all “reserved” characters with the exception of “?” and “/” should be percent-escaped in the query string.
Declaration
Objective-C
extern NSString *_Nonnull FWPercentEscapedStringFromString( NSString *_Nonnull string)Parameters
stringThe string to be percent-escaped.
Return Value
The percent-escaped string.
