在didSelectRowAtIndexPath之前调用viewDidLoad [英] viewDidLoad being called before didSelectRowAtIndexPath

问题描述

我有
viewDidLoad （下一个tableView）在之前调用didSelectRowAtIndexPath （当前的tableView ）。

I have viewDidLoad (of next tableView) being called before didSelectRowAtIndexPath (of current tableView).

我正在使用'singleton'来保存我的模型，到目前为止，这种方法运作良好。我试图将 didSelectRowAtIndexPath 中当前表中选择的行传递到目标 tableview （它们由以下链接：通过设置 didSelectRowAtIndexPath 中的变量来设置故事板中的segue。

I am using a 'singleton' to hold my model and up to now this has been working quite well. I am trying to pass on the row selected in the current table in didSelectRowAtIndexPath to the destination tableview (they are linked by a segue in storyboard) by setting by the variable in didSelectRowAtIndexPath.

然而，目的地 tableview 的 viewDidLoad 被调用在我可以设置行号之前。稍后调用 didSelectRowAtIndexPath 但到那时我已经为目标表设置了我的数据（错误地）。

However the viewDidLoad of the destination tableview is called before I can set the row number. didSelectRowAtIndexPath is called later but by then I have set up my data (wrongly) for the destination table.

推荐答案

使用segues时，您不需要 didSelectRowAtIndexPath：。您只需将segue链接到IB中的单元格即可。在代码中只需使用：

When using segues you do not need didSelectRowAtIndexPath:. You just link the segue to the cell in IB. In the code just use this:

-(void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
   CustomViewController *newVC = [segue destinationViewController];
   newVC.property = theDataYouWantToPass;
}

您可以通过发件人检索您的行传递的变量。

You can retrieve your row through the sender variable that is passed.

UITableViewCell *cell = (UITableViewCell *) sender;
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
NSInteger myRow = indexPath.row;
