Answer 1

@Ravi your array is an array of an array that is ShowList is an array that has the first object as an array, and this array is

  "viral_tweeter", default1571546, default1570056, twilightsaga, "wp-monetizer", viraltweetbuild, "building_a_list", yourtwittertips, "twitter_profit", mikesbi, mikesbizz, default1164341, incbizztest, default1164319, iprotv, iwantafreecopy1, tweeterbuilder, trafficlists, myadsensenews, mysafelistnews, myviralnews, safelistology, slmembers, slpmembers, twonderlandlist, noseospider, yseospider, digitallockdown, alistblueprint, classifiedtips, incbizzblog, "xit-trafficbeta", twwidget, jvtrafficfunnel, instantmlmspage, listbuldingmax, "incbizz_tips" 

so you can do something like this.

 NSString *cellValue = [[ShowList objectAtIndex:0] objectAtIndex:indexPath.row]; 

Answer 2

I assume the UILabel setText calls isEqualToString for some reason, so it crashes for the very first object in your array that is not NSString .
