UITableView，滚动到底部重新加载？ [英] UITableView , Scroll to bottom on reload?

问题描述

我有一个UITableView与动态更新的单元格。一切工作正常，除了当reload被调用（见下文）刷新cels在表中我希望表滚动到底部显示新的条目。

   - （void）reloadTable：（NSNotification *）notification {
 NSLog（@RELOAD TABLE ... ）; 
 [customTableView reloadData]; 
 //滚动到UITable的底部.... 
} 
  

我计划使用scrollToRowAtIndexPath：atScrollPosition：animated：但是，然后注意到，我没有访问indexPath。

解决方案

使用：

  NSIndexPath * ipath = [NSIndexPath indexPathForRow：cells_count-1 inSection：sections_count-1]; 
 [tableView scrollToRowAtIndexPath：ipath atScrollPosition：UITableViewScrollPositionTop animated：YES]; 
  

也可以手动指定段索引（如果一个段=> index = 0） p>

I have a UITableView with cells that are dynamically updated. Everything works fine apart from when reload is called (see below) to refresh the cels in the table I would like the table to scroll to the bottom to show the new entries.

- (void)reloadTable:(NSNotification *)notification {
    NSLog(@"RELOAD TABLE ...");
    [customTableView reloadData];
    // Scroll to bottom of UITable here ....
}

I was planning to use scrollToRowAtIndexPath:atScrollPosition:animated: but then noticed that I don't have access to an indexPath. Does anyone know how to do this, or of a delegate callback that I could use?

解决方案

Use:

NSIndexPath* ipath = [NSIndexPath indexPathForRow: cells_count-1 inSection: sections_count-1];
[tableView scrollToRowAtIndexPath: ipath atScrollPosition: UITableViewScrollPositionTop animated: YES];

Or you can specify the section index manually (If one section => index=0).
