copied!<p>You can create a category for <code>NSDictionary</code> to do this -- there isn't a standard way in the Cocoa library that I could find either. The code that I use looks like this:</p> <pre><code>// file "NSDictionary+UrlEncoding.h" #import <cocoa/cocoa.h> @interface NSDictionary (UrlEncoding) -(NSString*) urlEncodedString; @end </code></pre> <p>with this implementation:</p> <pre><code>// file "NSDictionary+UrlEncoding.m" #import "NSDictionary+UrlEncoding.h" // helper function: get the string form of any object static NSString *toString(id object) { return [NSString stringWithFormat: @"%@", object]; } // helper function: get the url encoded string form of any object static NSString *urlEncode(id object) { NSString *string = toString(object); return [string stringByAddingPercentEscapesUsingEncoding: NSUTF8StringEncoding]; } @implementation NSDictionary (UrlEncoding) -(NSString*) urlEncodedString { NSMutableArray *parts = [NSMutableArray array]; for (id key in self) { id value = [self objectForKey: key]; NSString *part = [NSString stringWithFormat: @"%@=%@", urlEncode(key), urlEncode(value)]; [parts addObject: part]; } return [parts componentsJoinedByString: @"&"]; } @end </code></pre> <p>I think the code's pretty straightforward, but I discuss it in some more detail at <a href="http://blog.ablepear.com/2008/12/urlencoding-category-for-nsdictionary.html" rel="noreferrer">http://blog.ablepear.com/2008/12/urlencoding-category-for-nsdictionary.html</a>.</p>
