i want information each wifi network name , noise / strength.can body tell me how it.

not sure if understand question. try make little bit more clear.

anyway, here's think understood.

nsstring *path = [[nsbundle mainbundle] pathforresource:@"/users/admin/desktop/wi-fi" oftype:@"txt"]; nsarray *categories = [nsarray arraywithcontentsoffile:path]; (nsdictionary *category in categories) {     nslog(@"%@", [category objectforkey:@"interfaces"]);     nslog(@"%@", [category objectforkey:@"software versions"]); } 

i haven't ran think should work, give shot. similar you're looking for. if not, it's in right direction , brings step closer finding answer. happy coding!

edit:

drag text file project , following

nsstring *path = [[nsbundle mainbundle] pathforresource:@"nsdictionarytextfile" oftype:@"txt"]; nsstring *content = [nsstring stringwithcontentsoffile:path encoding:nsutf8stringencoding error:null]; nsarray *testarray = [content componentsseparatedbystring:@"\n"]; nsstring *topdictionary = @""; nsmutabledictionary *dict = [nsmutabledictionary dictionary]; nsmutabledictionary *finaldict = [nsmutabledictionary dictionary]; for(nsstring *s in testarray){     nsarray *newarray = [s componentsseparatedbystring:@":"];     if([newarray[1] isequaltostring:@""]){         if([dict count] == 0){             topdictionary = newarray[0];         }         else{             topdictionary = [topdictionary stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]];             [finaldict setobject:[dict copy] forkey:[topdictionary copy]];             [dict removeallobjects];         }     } else{         nsstring *object = [newarray[1] stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]];         nsstring *key = [newarray[0] stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]];         [dict setobject:object forkey:key];     } } topdictionary = [topdictionary stringbytrimmingcharactersinset:[nscharacterset whitespaceandnewlinecharacterset]]; [finaldict setobject:dict forkey:topdictionary]; nslog(@"finaldict: %@", finaldict); 

* please not not finished ! have figure out more logic *

don't know how want them should give on how should work. didn't figure out complete logic adding top level dictionary , sub level dictionary should put in right directions. start removing trimming put in top dictionary , check empty/white space in front of string , use figure out dictionary supposed go. ie no empty space means highest 1 , more white spaces "inner" in dictionary. hope helps started.
