iOS: parse a URL into segments

Question

What\'s an efficient way to take an NSURL object such as the following:

foo://name/12345 

and break it up into one string and one unsigned

Answer 1

Thanks to Nick for pointing me in the right direction.

I wanted to compare file urls but was having problems with extra slashes making isEqualString useless. You can use my example below for comparing two urls by first de-constructing them and then comparing the parts against each other.

- (BOOL) isURLMatch:(NSString*) url1 url2:(NSString*) url2
{
    NSURL *u1 = [NSURL URLWithString:url1];
    NSURL *u2 = [NSURL URLWithString:url2];

    if (![[u1 scheme] isEqualToString:[u2 scheme]]) return NO;
    if (![[u1 host] isEqualToString:[u2 host]]) return NO;
    if (![[url1 pathComponents] isEqualToArray:[url2 pathComponents]]) return NO;

    //check some properties if not nil as isEqualSting fails when comparing them
    if ([u1 port] && [u2 port])
    {
        if (![[u1 port] isEqualToNumber:[u2 port]]) return NO;
    }

    if ([u1 query] && [u2 query])
    {
        if (![[u1 query] isEqualToString:[u2 query]]) return NO;
    }
    return YES;
}
