objective-c - 以编程方式选择行时未触发 didSelectRowAtIndexPath 事件

Question

我想在 tableView 中选择一个单元格。它使用此代码可以正常工作，但一旦以编程方式选择，它就不会触发 didSelectRowAtIndexPath 事件。我怎样才能触发它？

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];
[self.mainTable selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];

Answer 1

它按照记录工作:

Calling this method does not cause the delegate to receive a tableView:willSelectRowAtIndexPath: or tableView:didSelectRowAtIndexPath: message, nor will it send UITableViewSelectionDidChangeNotification notifications to observers.

选择单元格后自己调用:

NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0];

[self tableView:self.mainTable willSelectRowAtIndexPath:indexPath];
[self.mainTable selectRowAtIndexPath:indexPath animated:NO scrollPosition:UITableViewScrollPositionNone];
[self tableView:self.mainTable didSelectRowAtIndexPath:indexPath];
