from ios8 apple provide new uialertcontroller class can use instead of uialertview deprecated, stated in depreciation message

uialertview deprecated. use uialertcontroller preferredstyle of uialertcontrollerstylealert instead

so should use this

uialertcontroller * alert = [uialertcontroller                 alertcontrollerwithtitle:@"title"                                  message:@"message"                           preferredstyle:uialertcontrollerstylealert];    uialertaction* yesbutton = [uialertaction                     actionwithtitle:@"yes, please"                               style:uialertactionstyledefault                             handler:^(uialertaction * action) {                                 //handle yes please button action here                             }];  uialertaction* nobutton = [uialertaction                         actionwithtitle:@"no, thanks"                                   style:uialertactionstyledefault                                 handler:^(uialertaction * action) {                                    //handle no, button                                                 }];  [alert addaction:yesbutton]; [alert addaction:nobutton];  [self presentviewcontroller:alert animated:yes completion:nil];
