UITableview: How to Disable Selection for Some Rows but Not Others
You just have to put this code into cellForRowAtIndexPath
To disable the cell's selection property: (while tapping the cell)
cell.selectionStyle = UITableViewCellSelectionStyleNone;To enable being able to select (tap) the cell: (tapping the cell)
// Default stylecell.selectionStyle = UITableViewCellSelectionStyleBlue;// Gray stylecell.selectionStyle = UITableViewCellSelectionStyleGray;Note that a cell with selectionStyle = UITableViewCellSelectionStyleNone; will still cause the UI to call didSelectRowAtIndexPath when touched by the user. To avoid this, do as suggested below and set.
cell.userInteractionEnabled = NO;instead. Also note you may want to set cell.textLabel.enabled = NO; to gray out the item.
If you want to make a row (or subset of rows) non-selectable, implement the UITableViewDelegate method -tableView:willSelectRowAtIndexPath: (also mentioned by TechZen). If the indexPath should be not be selectable, return nil, otherwise return the indexPath. To get the default selection behavior, you just return the indexPath passed to your delegate method, but you can also alter the row selection by returning a different indexPath.
example:
- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath { // rows in section 0 should not be selectable if ( indexPath.section == 0 ) return nil; // first 3 rows in any section should not be selectable if ( indexPath.row <= 2 ) return nil; // By default, allow row to be selected return indexPath;}
Starting in iOS 6, you can use
-tableView:shouldHighlightRowAtIndexPath:If you return NO, it disables both the selection highlighting and the storyboard triggered segues connected to that cell.
The method is called when a touch comes down on a row. Returning NO to that message halts the selection process and does not cause the currently selected row to lose its selected look while the touch is down.
