How to reach the current selected cell in didSelectRowAtIndexPath?
提问by JaHelia
I want to change the accessory view type of a cell through the method: didSelectRowAtIndexPath , i.e. when a row is selected I want to change the accessory view type, can I do this inside that method ?
我想通过方法更改单元的辅助视图类型：DidselectRoyatindexpath，即选择一行时，我想更改附件视图类型，我可以在该方法内完成吗？

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
UITableViewCell *myCell = [tableView cellForRowAtIndexPath:indexPath];
// Access accessory View as below.
UIView * myCellAccessoryView = myCell.accessoryView;
}

Use the below function and pass the index path of the selected row so that the particular cell is reloaded again.
使用以下函数并传递所选行的索引路径，以便再次重新加载特定单元格。
- (void)reloadRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation
Another solution: store the selected row index and do a reload of tableview. Then in cellForRowAtIndexPathcheck for the selected row and change the accessory view of the cell.
另一种解决方案：存储选定的行索引并重新加载 tableview。然后cellForRowAtIndexPath检查所选行并更改单元格的附件视图。

Store selected indexpath. for eg: NSInteger selectedIndexPath; then follow the step below. set your accessory view.
存储选定的索引路径。例如：NSInteger selectedIndexPath; 然后按照以下步骤操作。设置您的附件视图。
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
AddressTableViewCell *cell=(AddressTableViewCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell.backgroundColor=[UIColor lightGrayColor];
Address *addr=[self.locationArray objectAtIndex:indexPath.row];
cell.titleLabel.text = addr.addressTitle;
cell.detailLabel.text = addr.addressDetail;
if (indexPath.row == selectedIndexPath) {
[cell.selectButton setImage:[UIImage imageNamed:@"checkboxFilled"] forState:UIControlStateNormal];
}
else {
[cell.selectButton setImage:[UIImage imageNamed:@"checkbox"] forState:UIControlStateNormal];
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
selectedIndexPath=indexPath.row;
[self.tableView reloadData];
}
