how must ? im sure understand i'm new @ objective c

thank you

you need basic nsstring documentation find method that, stringwithformat:.

nsstring *urlstring = [nsstring stringwithformat:@"http://api.openweathermap.org/data/2.5/find?q=%@&units=metric", townlocation]; nsdata *data = [nsdata datawithcontentsofurl:[nsurl urlwithstring:urlstring]];

if you're new @ objective-c, place find information search internet or ios developer library class in question (in case, nsstring) find myriad of resources @ disposal. doc check formatting string objects, linked in stringwithformat: section of ios developer library, find more info formatting strings.
