Question

I have an NSMutableArray of NSString objects. How would I make an NSString that consists of all the elements in that array joined together with semicolons in between?

For example:

array = "hello","hi","bye",nil;
output = "hello;hi;bye";

Answer 1

NSMutableArray *array = [NSMutableArray arrayWithObjects:@"hello", @"hi", @"bye", nil];
NSString *output = [array componentsJoinedByString:@";"];
