iPhone-SDK：启动期间的活动指示器？ [英] iPhone-SDK:Activity Indicator during Startup?

问题描述

我的项目中有一个Default.png文件，因此只要我的应用程序启动Default.png文件，就会在那里加载。由于我的应用程序在启动时（应用程序启动）从服务器检索数据，我想在Default.png文件加载时显示活动指示器。是否可以一次激活该过程，我的意思是在启动期间一次显示Default.png并启用活动指示器？
但我尝试将活动指示器代码放在'applicationDidFinishLaunching'中，但在显示Default.png文件时它没有显示活动指示器。但我确信活动代码我所拥有的，在其他屏幕上工作正常。问题仅在应用启动期间。

I am having a Default.png file in my project, so that whenever my app launches Default.png file loads there. As my app is retrieving data from server at startup(app launch), i want to show activity indicator as well while Default.png file is loading. Is it possible to activate both the process at a time, i mean showing Default.png and enable activity indicator at a time during startup? But i tried putting Activity Indicator code in 'applicationDidFinishLaunching' but it doesn't show activity indicator at the time of showing Default.png file. But i am sure that Activity code what i have, is working fine on other screens. Problem is only during app launch.

有人可以分享您的想法吗？

推荐答案

你不能在Default.png中做任何动画图片。您应该使用视图/控制器（包含活动指示器）尽快替换它。比显示控制器后，加载您的数据和可能的其他控制器（在线程中）。

You can't do any animation in the Default.png image. You should replace it as soon as possible with a view/controller (containing the activity indicator). Than after showing that controller, load your data and possibly an other controller (in a thread).
