UITableView select and deselect row
提问by HurkNburkS
I have a UITableViewcell that stays highlighted after touching it. I would like to know how to remove the highlight right after it becomes visible after your touch.
我有一个 UITableViewcell 在触摸它后保持突出显示。我想知道如何在触摸后立即删除突出显示。
So when you touch the UITableViewCell I would like it to become selected and highlighted then when the user raises their finger I would like to deselect and unhighlight the UITableViewCell.
因此，当您触摸 UITableViewCell 时，我希望它被选中并突出显示，然后当用户抬起手指时，我希望取消选择并取消突出显示 UITableViewCell。
This is what I am doing so far, and the deselect works but the cell is still highlighted.
这就是我到目前为止所做的，取消选择有效，但单元格仍然突出显示。
#pragma mark -- select row
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(@"%@", indexPath);
NSLog(@"%@", cell.textLabel.text);
}
#pragma mark -- deselect row
-(void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}

-(void) tableView:(UITableView *)tableView didDeselectRowAtIndexPath:
(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
That's an infinite loop, I'm quite certain. However... it's sort of on the right track. You can move that method call into didSelectRowAtIndexPath:.
这是一个无限循环，我很确定。然而......它有点走在正确的轨道上。您可以将该方法调用移动到didSelectRowAtIndexPath:.
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:
(NSIndexPath *)indexPath {
//stuff
//as last line:
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
For that matter, deselectRowAtIndexPathcan be called from anywhere at any time you want the row to be deselected.
就此而言，deselectRowAtIndexPath可以随时从任何您希望取消选择该行的地方调用。
[self.myTableView deselectRowAtIndexPath:[self.myTableView
indexPathForSelectedRow] animated: YES];

You need to deselect row on didSelectRowAtIndexPathmethod
您需要在didSelectRowAtIndexPath方法上取消选择行
Example code
示例代码
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
}
