Question

I need to substring to the 2nd comma in an NSString.

Input:

NSString *input = @"title, price, Camry, $19798, active";

Desired Output:

NSString *output = @"title, price";

Thanks!

UPDATE:

I have the following but the problem is it needs to skip the last comma:

NSString *output = [input rangeOfString:@"," options:NSBackwardsSearch];

Answer 1

this code should do what you need:

NSString *input = @"title, price, Camry, $19798, active";

NSArray *array = [input componentsSeparatedByString:@","];

NSArray *subArray = [array subarrayWithRange:NSMakeRange(0, 2)];

NSString *output = [subArray componentsJoinedByString:@","];

NSLog(output);
