NSURL parsing

got something good, paste it here

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url {

NSLog(@"%@", url);

    NSURL *url1 = [NSURL URLWithString:@"httpdd://www.mobileorchard.com"];

    NSLog(@"scheme: %@", [url scheme]);

    NSLog(@"host: %@", [url host]);

    NSLog(@"port: %@", [url port]);

    NSLog(@"path: %@", [url path]);

    NSLog(@"path components: %@", [url pathComponents]);

    NSLog(@"parameterString: %@", [url parameterString]);

    NSLog(@"query: %@", [url query]);

    return YES;

}

@interface NSString (ParseCategory)
- (NSMutableDictionary *)explodeToDictionaryInnerGlue:(NSString *)innerGlue outterGlue:(NSString *)outterGlue;
@end
@implementation NSString (ParseCategory)
- (NSMutableDictionary *)explodeToDictionaryInnerGlue:(NSString *)innerGlue outterGlue:(NSString *)outterGlue {
    // Explode based on outter glue
    NSArray *firstExplode = [self componentsSeparatedByString:outterGlue];
    NSArray *secondExplode;

    // Explode based on inner glue
    NSInteger count = [firstExplode count];
    NSMutableDictionary *returnDictionary = [NSMutableDictionary dictionaryWithCapacity:count];
    for (NSInteger i = 0; i < count; i++) {
        secondExplode = [(NSString *)[firstExplode objectAtIndex:i] componentsSeparatedByString:innerGlue];
        if ([secondExplode count] == 2) {
                [returnDictionary setObject:[secondExplode objectAtIndex:1] forKey:[secondExplode objectAtIndex:0]];
        }
    }

    return returnDictionary;
}
@end

It's called like this:

NSMutableDictionary *parsedQuery = [[myNSURL query] explodeToDictionaryInnerGlue:@"=" outterGlue=@"&"]

For parsing the path portion of the NSURL (ie @"/partA/partB/partC"), just call this:

NSArray *parsedPath = [[nyNSURL path] componentsSeperatedByString:@"/"];

Be aware that parsedPath[0] will be an empty string because of the leading /!

EDIT - Here is a Category extension to NSURL for your usage pleasure. It strips the initial "/" so you don't have an empty 0 index.

@implementation NSURL (ParseCategory)
- (NSArray *)pathArray {
    // Create a character set for the slash character
    NSRange slashRange;
    slashRange.location = (unsigned int)'/';
    slashRange.length = 1;
    NSCharacterSet *slashSet = [NSCharacterSet characterSetWithRange:slashRange];

    // Get path with leading (and trailing) slashes removed
    NSString *path = [[self path] stringByTrimmingCharactersInSet:slashSet];

    return [path componentsSeparatedByCharactersInSet:slashSet];
}
- (NSDictionary *)queryDictionary {
    NSDictionary *returnDictionary = [[[[self query] explodeToDictionaryInnerGlue:@"=" outterGlue:@"&"] copy] autorelease];
    return returnDictionary;
}
@end
