NSString's Split and Join crash course

Split NSString using the NSString instance method componentsSeparatedByString

NSString *mystring = @"coding;is;kind;of;magic";
NSArray *mysplitedstring = [mystring componentsSeparatedByString: @";"];

The above code will produce an array containing the following element:

coding
is
kind
of
magic

To join an array of NSString back to a single NSString, use the NSArray instance method componentsJoinedByString

NSString *mystring = [mysplitedstring componentsJoinedByString:@";"];

That will give you back the NSString

"coding;is;kind;of;magic"
