NSURL is fully equipped to resolve relative strings against another URL, but sadly there's no API to go in the opposite direction. KSURLUtilities to the rescue!
- (NSString *)ks_stringRelativeToURL:(NSURL *)URL; - (NSURL *)ks_URLRelativeToURL:(NSURL *)URL;
How's this work? Well, everyone loves examples right?
It's common for URLs to split their query string up into a dictionary-like series of parameters. e.g.
KSURLUtilities has an easy solution for getting that into a more Cocoa-friendly form:
- (NSDictionary *)ks_queryParameters;
There are also APIs for creating/deriving new URLs from a dictionary:
- (NSURL *)ks_URLWithQueryParameters:(NSDictionary *)parameters; + (NSURL *)ks_URLWithScheme:(NSString *)scheme host:(NSString *)host path:(NSString *)path queryParameters:(NSDictionary *)parameters;
Mac OS X 10.6 gave us a bunch of new URL methods like
-URLByDeletingLastPathComponent. If you wanted access to this behaviour before, it necessitated much tedious mucking about with
NSString path methods, or using
CFURL functions. KSURLUtilities gives simple Cocoa APIs for all these tasks on 10.5 and earlier:
- (NSString *)ks_lastPathComponent; - (NSString *)ks_pathExtension; - (NSURL *)ks_URLByAppendingPathExtension:(NSString *)pathExtension; - (NSURL *)ks_URLByDeletingLastPathComponent; - (NSURL *)ks_URLByDeletingPathExtension; - (BOOL)ks_hasDirectoryPath; - (NSURL *)ks_URLByAppendingPathComponent:(NSString *)pathComponent isDirectory:(BOOL)isDirectory;
Nothing fancy here, just a few additions to the built-in
-[NSURL host] method.
- (NSURL *)ks_hostURL;
Strips a URL down to nothing but its scheme and host. e.g.
- (NSArray *)ks_domains;
Splits the host up into its domains. e.g.
(www, karelia, com)
NSFormatter subclass for handling URLs.
- Non-complete URLs like
- Host URLs have a slash appended to them. e.g.
http://example.comis displayed/interpreted as
+URLFromStringmethod that takes care of unescaped characters
A simple class that represents a URL, optionally with a title attached. Features:
- Handles Web Location files (e.g. those created by dragging a URL from Safari)
You can pull in the WebKit.framework-dependent KSWebLocationPasteboardAdditions too, to (unsurprisingly) gain support for reading and writing Web Locations from/to the pasteboard.
