使用Xcode6在iOS中启动屏幕上的活动指示器

问题描述：

是否可以在Xcode6的启动画面中使用UIActivityIndicator

Is it possible to use UIActivityIndicator in launch screen with Xcode6

我试过但它不是动画，不确定它是否可能。

I tried but its not animating, not sure whether its possible or not.

任何人都可以尝试这个或知道它是否可能吗？

Can anyone tried this or knows whether its possible or not?

谢谢 -

您要实现的目标是在启动屏幕中显示ActivityIndicator，这是不可能的，但您可以通过某种不同的方式实现它。

What you are trying to achieve is to show ActivityIndicator during launch screen which is not possible, but you can achieve it by some different way.

以下是可以帮助您的想法：

Here is the idea that may help you:

创建单独的加载页面&从App delegate中的didFinishLaunchingWithOptions方法调用它

添加Splash图像&指标

您可以设置2-3秒的计时器，而不是重定向到您的第一页应用

使用指示灯时确保你已经检查过StartAnimating为true或者只是以编程方式添加指标如下：

Create separate loading page & call it from didFinishLaunchingWithOptions method in App delegate
Add Splash image & indicator to it
You can set timer of 2-3 seconds than redirect to your first page of app
While using indicator make sure you have checked StartAnimating to true or simply add indicator programmatically like this:

UIActivityIndicatorView *activity = [[UIActivityIndicatorView alloc]  initWithFrame:CGRectMake(225, 115, 30, 30)];

[activity setBackgroundColor:[UIColor clearColor]]; 

[activity setActivityIndicatorViewStyle: UIActivityIndicatorViewStyleGray];

[self.view addSubview: activity];

[activity startAnimating];

希望它适合你。
