Add toString method to APAddress class about apaddressbook

[austin-bowen-advyon]

Okay, I just wrote one.

APAddress.h:
- (NSString *) toString;

APAddress.m:

- (NSString *) toString
{
    BOOL hasStreet      = (self.street      && [self.street length]);
    BOOL hasCity        = (self.city        && [self.city length]);
    BOOL hasState       = (self.state       && [self.state length]);
    BOOL hasZip         = (self.zip         && [self.zip length]);
    BOOL hasCountry     = (self.country     && [self.country length]);
    BOOL hasCountryCode = (self.countryCode && [self.countryCode length]);
    BOOL countryCodeIsNumeric = ([[NSNumberFormatter new] numberFromString:self.countryCode] != nil);

    NSMutableString *str = [NSMutableString new];

    // Street
    if (hasStreet)
    {
        [str appendString:[self.street capitalizedString]];
        [str appendString:@", "];
    }

    // City
    if (hasCity)
    {
        [str appendString:[self.city capitalizedString]];
        [str appendString:@", "];
    }

    // State
    if (hasState)
    {
        if ([self.state length]) > 2)
            [str appendString:[self.state capitalizedString]];
        else
            [str appendString:[self.state uppercaseString]];
        if (hasZip) [str appendString:@" "];
        else        [str appendString:@", "];
    }

    // Zip
    if (hasZip)
    {
        [str appendString:self.zip];
        [str appendString:@", "];
    }

    // Country
    if (hasCountryCode && !countryCodeIsNumeric)
        [str appendString:[self.countryCode uppercaseString]];
    else if (hasCountry)
        [str appendString:[self.country capitalizedString]];

    // Clean up the string
    [str setString:[str stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@", \t\n"]]];

    return [NSString stringWithString:str];
}

Looks good but in different countries different address formats. So, it's not suitable for all.
You can create category on APContact and use it your projects
