iOS启动屏幕上的动画活动指示器

问题描述

是否可以在iOS启动屏幕上使用 UIActivityIndi​​cator ？

Is it possible to use UIActivityIndicator on the iOS launch screen?

我尝试过，但是不设置动画。

有人尝试过此方法还是不知道是否可能？

Has anyone tried this or know whether it's possible?

推荐答案

您要实现的目标是在启动屏幕上显示ActivityIndi​​cator，但这是不可能的，但是您可以通过其他方法来实现它。

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.

以下想法可能会为您提供帮助：

Here is the idea that may help you:

• 创建单独的加载页面&从应用程序委托中的didFinishLaunchingWithOptions方法调用它


• 添加启动画面&指示器


• 您可以将计时器设置为2-3秒，而不是重定向到应用程序的首页



• 同时使用指示器确保您已将StartAnimating检查为true或仅以编程方式像这样添加指示器：

• 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];

希望它对您有用。
