Divide 1 NSString into two NSStrings by whiteSpace

Question

I have NSStringone that originally looked like <a href="http://link.com"> LinkName</a>. I removed the html tags and now has NSStringone that looks like

http://Link.com   SiteName

how can I divide these two into different ones NSStringso that I have

http://Link.com

and

SiteName

I specifically want to show SiteNamein the label and just use http://Link.comto open in UIWebView, but I can’t when all is one line. Any suggestions or help are appreciated.

Answer 1

NSString *s = @"http://Link.com   SiteName";
NSArray *a = [s componentsSeparatedByCharactersInSet:[NSCharacterSet whitespaceCharacterSet]];
NSLog(@"http: '%@'", [a objectAtIndex:0]);
NSLog(@"site: '%@'", [a lastObject]);

NSLog Output:

http: 'http://Link.com'
site: 'SiteName'

Bonus, handle the site name with embedded space with RE:

NSString *s = @"<a href=\"http://link.com\"> Link Name</a>";
NSString *pattern = @"(http://[^\"]+)\">\\s+([^<]+)<";

NSRegularExpression *regex = [NSRegularExpression
                              regularExpressionWithPattern:pattern
                              options:NSRegularExpressionCaseInsensitive
                              error:nil];

NSTextCheckingResult *textCheckingResult = [regex firstMatchInString:s options:0 range:NSMakeRange(0, s.length)];
NSString *http = [s substringWithRange:[textCheckingResult rangeAtIndex:1]];
NSString *site = [s substringWithRange:[textCheckingResult rangeAtIndex:2]];

NSLog(@"http: '%@'", http);
NSLog(@"site: '%@'", site);

NSLog Output:

http: 'http://link.com'
site: 'Link Name'

NSString has a method with a signature:

componentsSeparatedByString:

. :

NSArray *components = [myNSString componentsSeparatedByString:@" "];

[components objectAtIndex:0]; //should be SiteName
[components objectAtIndex:1]; // should be http://Link.com
