objective c - Multiple Substrings in String -


i´m working on app displays 6 pictures website. these pictures change on time extracted sourcecode of said website , managed pull first of 6 pictures code:

nserror *error = nil; nsstring *deviantstringpopular; deviantstringpopular = [nsstring stringwithcontentsofurl:[nsurl     urlwithstring:@"http://browse.deviantart.com/?order=24"]                                          encoding:nsisolatin1stringencoding                                             error:&error]; nsstring *popularcontent; nsrange popularurlrange1 = [deviantstringpopular rangeofstring:@"super_img=\""]; nsrange popularurlrange2 = [deviantstringpopular rangeofstring:@"\" super_w"]; int lengt = popularurlrange2.location - popularurlrange1.location -     popularurlrange1.length; int location = popularurlrange1.location + popularurlrange1.length; nsrange endrange; endrange.location = location; endrange.length = lengt; popularcontent = [deviantstringpopular substringwithrange:endrange]; nslog(@"%@", popularcontent);

the problem is, other 5 images' urls between same substrings first one. possible first image's url ignored once it´s loaded , second 1 loads , stored under different variable , on?

thanks in advance

to 6 urls string , load them different variables, try using loop. each iteration, after substring found , stored variable, make range beginning of string end of substring found. can use stringbyreplacingcharactersinrange erase part of string searched next time search string substring, find next url.
