ios - UITableView won't present -

i have strange situation in app , can't explain or locate bug. have uiviewcontroller tableview in it. in table view have 3 prototype cells, have 2 section divided so:

first section: row 0 (cell id: episodescrollerscell) second section: row 0 (cell id: addcommentscell) : row 1+ (cell id: commentcell)

the required methods in protocol listed below.

- (nsinteger)numberofsectionsintableview:(uitableview *)tableview {     return 2; }  - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section {     nsinteger rownum;     if(section == 0){         rownum = 1;     }else{         rownum = 1; // here problem. if change number of row above 1     }     return rownum; }  - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellidentifier;     if(indexpath.section == 0){         cellidentifier = episodescrollerscell;     }else if (indexpath.section == 1 && indexpath.row == 0){         cellidentifier = addcommentscell;     }else{         cellidentifier = commentcell;     }     uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier];      return cell; } 

now problem arises when want have 2 rows or above in second section (i.e have 2 prototype cells in 1 section), view controller won't show. i've logged cellforrowatindexpath: method see if cells gets loaded , do.

any advice? thanks,

what seem doing trying dequeue reusable cell chance no cell has been created before. however, if no cells have been created/allocated, dequeue return nil value. tells program given indexpath there no cell displayed.

so, if nil value dequeue function, table try create new cell given cell identifier. so, suggest following:

- (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath {     static nsstring *cellidentifier;     if(indexpath.section == 0){         cellidentifier = episodescrollerscell;     }else if (indexpath.section == 1 && indexpath.row == 0){         cellidentifier = addcommentscell;     }else{         cellidentifier = commentcell;     }     uitableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellidentifier];     if(!cell){         if(indexpath.section == 0){             //initialise new cell here, through nib or code             //for eg. cell = [[uitableviewcell alloc] initwithstyle: ...];         }         //do specific initialisation each type of cell need here     }     return cell; } 

this way, when dequeue function returns nil value, program automatically creates new cell fit in place.

hope helps.
