- (void)dismisspop2:(nsstring *)projectname {     projectdelete = projectname;     nsstring *msg = [nsstring stringwithformat:@"are sure want delete project (%@)?",projectname];     uialertview *alert = [[uialertview alloc] initwithtitle:@"- project deletion -"                                                 message:msg                                                delegate:self                                       cancelbuttontitle:@"cancel"                                       otherbuttontitles:@"delete", nil];     [alert settag:100];     [alert show]; }  - (bool)alertviewshouldenablefirstotherbutton:(uialertview *)alertview { // validation     if ([alertview tag] == 100) {         return yes;     }      else {         return yes;     } }  - (void)alertview:(uialertview *)alertview diddismisswithbuttonindex:(nsinteger)buttonindex {     if ([alertview tag] == 100) {     // deleting project     if (buttonindex == 1) {         // since user has tapped yes     } }
