Iphone 自定义tableview单元格未刷新

iphone uitableview

Iphone 自定义tableview单元格未刷新,iphone,uitableview,Iphone,Uitableview,这是我的自定义表视图单元格，我希望每1分钟更改一次这些值（值将从服务器加载）。我已经设置了Nstimer并尝试重新加载tableview。数组中的数据变化良好，但uitableviewcell中的值没有变化代码： Tableviewcontroller.m -(void) loadView { parsejson = [ParseJson alloc]; defaults=[NSUserDefaults standardUserDefaults]; items=[NSArray array

[self.tableView reloadData];

而不是

   UITableView *tv = (UITableView *)self.view;
  [tv reloadData];

仅当您的超类是UITableViewController时才可以。如果不是，则为tableView创建一个出口并通过它重新加载表格

您是否将此“setNeedsDisplay”用作

[cell.data11 setNeedsDisplay] if cellForRow is calling.
