如果蓝牙关闭 iOS 则禁用警告对话框 [英] Disable Warning Dialog if Bluetooth is powered off iOS

问题描述

我的 ios 应用程序使用蓝牙连接到一个配件.如果未启用蓝牙，则会出现一个弹出窗口，要求我激活.

My ios application uses bluetooth to connect to an accessory. If Bluetooth is not enabled, a popup appears asking me to activate.

我注意到每次运行应用程序时都会出现弹出窗口.

I noticed that popup appears every time I run the application.

我的问题是是否可以显示一次弹出窗口，即仅在第一次启动后(fitbit 应用程序这样做.我也想知道是否可以更改弹出窗口的语言.

My question is whether it is possible to display the popup once, ie only after the first launch (fitbit app do that. I also want to know if it is possible to change the language of the popup.

我的应用程序适用于 iOS7 和 iOS6

My application is for iOS7 and iOS6

如果我们无法更改语言，有没有办法禁用此弹出窗口，然后我将使用本地化系统开发自己的视图(弹出窗口)?

If we can't change the langage, is there a way to disable this popup then i will develop my own view (popup) with localized system ?

非常感谢！

推荐答案

我收到了一位苹果开发者的回复:在 iOS7 中，CBCentralManagerOptionShowPowerAlertKey 选项可让您禁用此警报.

I got the following response from an apple developer : In iOS7, the CBCentralManagerOptionShowPowerAlertKey option lets you disable this alert.

如果你有一个CBCentralManager，那么当你初始化它时，你可以使用方法-[CBCentralManager initWithDelegate:queue:options]

If you have a CBCentralManager, then when you initialise it, you can use the method -[CBCentralManager initWithDelegate:queue:options]

在我的 .h 文件中，我有一个 CBCentralManager * manager.

In my .h file, I have a CBCentralManager * manager.

在我的 .m 文件中:

In my .m file:

NSDictionary *options = @{CBCentralManagerOptionShowPowerAlertKey: @NO};
    
_manager = [[CBCentralManager alloc] initWithDelegate:self queue:nil options:options];
    
[_manager scanForPeripheralsWithServices:nil options:options];

使用此代码，警告不再出现.希望能帮到你！

With this code, the warning no longer appears. I hope that helps!
