Solution

  • Try this code. With regrular expression we parse substring in []. After split string by ,

    NSRegularExpression *regex = [NSRegularExpression regularExpressionWithPattern:@"\\[(.*?)\\]" options:NSRegularExpressionCaseInsensitive error:NULL];
NSString *test = @"[[[\"OK\",\"ok\",\"\",\"OK\",0]],,\"AB\",,[[\"hello\",[1],YES,YES,100,0,4,0]],[[\"ok\",1,[[\"okidoki\",100,yes,yes]],[[0,3]],\"okdoki\"]],,[,\"I am here\",[4]],[[\"AB\"]],3]";
NSString *input = test;
NSArray *myArray = [regex matchesInString:input options:0 range:NSMakeRange(0, [input length])] ;

NSMutableArray *matches = [NSMutableArray arrayWithCapacity:[myArray count]];

NSRange matchRange = [myArray[4] rangeAtIndex:1];
[matches addObject:[input substringWithRange:matchRange]];
NSString *elementString = [matches lastObject];
NSArray *listItems = [elementString componentsSeparatedByString:@","];
NSLog(@"I'm here: %@", listItems[1]);
