objective c - how to create different settings for each UITableViewCell -

i have tableview multiple sections.

i want make of them selectable, , others not. also, cells selectable should link different viewcontrollers.

does have idea how this?

the best way found manage per-cell information create cell-info class, , have represent data. on class, can flag whether cell selectable, type, handler, etc.

then, after dequeueing cell, prepare display according cell-info backing object.

example:

@interface mycellinfo  @property (nonatomic, copy) nsstring* title; @property (nonatomic, copy) nsstring* detail; @property (nonatomic, strong) uiimage* image; @property (nonatomic, getter=isselectable) bool selectable; @property (nonatomic) sel handlingselector; ...  @end  @implementation mycellinfo @end 

this defines example cell-info class holds properties on each cell. ease of use, register cell class in table example identifier in viewdidload:

[self.tableview registerclass:[uitableviewcell class] forcellreuseidentifier: @"exampleidentifier"]; 

your table view data source:

- (nsinteger)numberofsectionsintableview:(uitableview *)tableview {     return datasource.count; }  - (nsinteger)tableview:(uitableview*)tableview numberofrowsinsection:(nsinteger)section {     return [datasource[section] count]; }  - (uitableviewcell*)tableview:(uitableview*)tableview cellforrowatindexpath:(nsindexpath*)indexpath {     uitableviewcell* cell = [tableview dequeuereusablecellwithidentifier:@"exampleidentifier"];      mycellinfo* cellinfo = datasource[indexpath.section];      if(cellinfo.image == nil)     {         //show image     }     else     {         [cell.textlabel settext:cellinfo.title];         [cell.detailtextlabel settext:cellinfo.detail];     }      return cell; } 

your table view delegate:

- (cgfloat)tableview:(uitableview*)tableview heightforrowatindexpath:(nsindexpath*)indexpath {     mycellinfo* cellinfo = datasource[indexpath.section];      return cellinfo.height; }  - (bool)tableview:(uitableview*)tableview shouldhighlightrowatindexpath:(nsindexpath*)indexpath {     mycellinfo* cellinfo = datasource[indexpath.section];      return cellinfo.selectable; }  - (nsindexpath*)tableview:(uitableview*)tableview willselectrowatindexpath:(nsindexpath*)indexpath {     mycellinfo* cellinfo = datasource[indexpath.section];      return cellinfo.selectable ? indexpath : nil; }  - (void)tableview:(uitableview*)tableview didselectrowatindexpath:(nsindexpath*)indexpath {     mycellinfo* cellinfo = datasource[indexpath.section];      [self performselector:cellinfo.handlingselector withobject:cellinfo]; } 

all remains create data , represent each entry mycellinfo object. used array of arrays type of db, top level array represents sections, while each inner array section's cells, each mycellinfo object.
