UITableViewCell with a UIButton
I have UITable which contains some UIButtons. I would like a way to use the label.
The problem I have is that I need two tag labels, one for retrieving the cell in tableviewCellWithReuseIdentifier and configureCell.
Until recently I have been using the UIButton.title to determine which row in the table I selected. The (invisible) text was the row number.
Now I need to use the title for some visible text. How can I still find which row was pressed?
When I press the area outside the button the usual didSelectRowAtIndexPath is called. The hard part is that I want to capture both the UI开发者_C百科Button (which calls its own selector) and the row, which I had been finding out from the title. Now I need the title for something else.
I use something like this. This will get you the indexpath in the tableview.
- (IBAction)buttonAction:(id)sender {
UIButton *button = (UIButton *)sender;
CGPoint buttonOriginInTableView = [button convertPoint:CGPointZero toView:tableView];
NSIndexPath *indexPath = [tableView indexPathForRowAtPoint:buttonOriginInTableView];
// do something
}
You could subclass UITableViewCell or UIButton and add some properties.
You should implement the UITableViewDelegate
protocol.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// Do something based on selected row (indexPath.row)
}
Implement the UITableViewDelegate protocol. It will help you and do what you need.
didSelectRowAtIndexPath
is autmatically called whenever a row is selected in your table.
in your .m file the one with the table view controller if there isn't one there add this method:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
// NSInteger row = [indexPath row];
// or (indexPath.row)
// do whatever you like with this value which tells you which row is selected.
}
