iPhone等效于Application.DoEvents(); [英] iPhone equivalent of Application.DoEvents();

问题描述

iPHone:我们使用MonoTouch，但是Obj-C的答案还可以.

iPHone: We use MonoTouch, but Obj-C answers are ok.

我的单例域对象需要一段时间才能获取所有数据，因此它在线程中内部运行部分提取.

My singleton domain object takes a while to get all the data so it runs internally parts of the fetch in a thread.

我需要通知UI该域已完成.目前，我正在这样做.有没有更好的办法?在WinForms中，我将调用Application.DoEvents()而不是Thread Sleep.

I need to inform the UI that the domain is done. Currently I do this. Is there a better way? In WinForms I would call Application.DoEvents() instead of Thread Sleep.

PlanDomain domain = PlanDomain.Instance ();
while (domain.IsLoadingData)
{
    Thread.Sleep (100);  //this is the main UI thread
}

TableView.Hidden = false;
TableView.Source = new TableSource (this);
TableView.ReloadData ();

推荐答案

通常来说，您想避免使用DoEvents. Objective-c中的iPhone等价物如下所示:

Generally speaking you want to avoid DoEvents. The iPhone equivilant in objective-c looks something like this:

[[NSRunLoop currentRunLoop] runUntilDate:[NSDate date]];
