iphone - TableView not displaying correctly and crashing, -

-

i have tableview in midddle of tab bar template application.. wanted add contents of nsmutablearray called 'routines'.

here .h file

#import <uikit/uikit.h>   @interface firstviewcontroller : uiviewcontroller <uitableviewdelegate, uitableviewdatasource> {  nsmutablearray *routines; }  @property (nonatomic, retain) nsmutablearray *routines;  - (ibaction)showneweventviewcontroller;       @end

and .m file.

#import "firstviewcontroller.h" #import "neweventviewcontroller.h"  @implementation firstviewcontroller  @synthesize routines;    - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {  return [routines count];  }   - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {  static nsstring *cellidentifier = @"cell";  uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier]; if (cell == nil) {     cell = [[[uitableviewcell alloc] initwithframe:cgrectzero reuseidentifier:cellidentifier] autorelease]; }  // set cell... nsstring *cellvalue = [routines objectatindex:indexpath.row]; [cell.textlabel settext:cellvalue];  return cell; }

and viewdidload method

- (void)viewdidload {  routines = [[nsmutablearray alloc] init];  [routines addobject:@"hello"]; [routines addobject:@"temp"]; [routines addobject:@"temp2"]; [routines addobject:@"temp3"]; [routines addobject:@"temp4"]; self.navigationitem.title = @"test";   }

my objects not displaying. can see, have added

and have hooked in ib correctly.

when try open app ( return) crashes, , spits out following log.

i have no idea going wrong, since im bit of newbie.

thanks guys!

sam

it looks you've assigned datasource of table uitabbarcontroller, rather firstviewcontroller object. second line of pasted error message saying it's trying numberofrows, datasource doesn't implement it. double check connections in ib.
