The "red banner" indicates that your application is currently using the microphone hardware. It is shown by applications that have active control over the main recording context, and hides when your application releases it's hold on the recording context (such as when the home button is pressed). Because you cannot predict when the home button will be pressed to exit your application, you will need to either support background recording to persist the banner (then gracefully release your context after a second or two to have the status bar animate back to black), or somehow terminate your context before the application closes.
“红色横幅”表示您的应用程序当前正在使用麦克风硬件。它由对主记录上下文具有主动控制权的应用程序显示，并在您的应用程序释放它对记录上下文的保持时隐藏（例如按下主页按钮时）。因为您无法预测何时按下主页按钮以退出您的应用程序，您将需要支持后台录制以保留横幅（然后在一两秒后优雅地释放您的上下文以使状态栏动画恢复为黑色），或者在应用程序关闭之前以某种方式终止您的上下文。
