this line of code

[contactslist init:tablerowvalue]; 

i getting following warning :expression result unused

and in contactslist class init method not being called

thank help

the contactlist object initialized in initwithnibname: method, in turn calls init method inherited nsobject (with no parameters).

if need setup view after initialization create method named "setupwithtablerowvalue:" or similar.
