如何在xcode(swift)和phonegap中在后台将iPhone作为信标运行 [英] How to run iPhone as a beacon in background in both xcode(swift) and phonegap
问题描述
我设法创建了一个将手机转变为信标发射器的应用程序.
I managed to create an app which turns the phone into a beacon emitter.
它在xcode(Swift)和phonegap上正常工作.
It works fine on xcode (Swift) and phonegap .
对我来说，下一步是使其在后台作为信标工作(我正在为iOS 10开发).
The next step for me is making it work in the background as a beacon (I'm developing for iOS 10).
我在网上发现了与此类似的问题，但它们都已过时，即旧的ios，Objective-C和过时的插件
I found similar questions to this online but all of them were out of date ie old ios , objective-C and outdate plug-ins
如果有人可以向我提供一个有效的示例或指导我针对xcode s(wift)和phonegap更改代码的内容，我将非常感谢
would really appreciate it if someone can provide me with a working example or guide me on what to change in my code for both an xcode s(wift) and phonegap

var beaconRegion = new cordova.plugins.locationManager.BeaconRegion(identifier, uuid, major, minor);
var delegate = new cordova.plugins.locationManager.Delegate();
delegate.peripheralManagerDidStartAdvertising = function(pluginResult) {

// Event when bluetooth transmission state changes
// If 'state' is not set to BluetoothManagerStatePoweredOn when advertising cannot start
delegate.peripheralManagerDidUpdateState = function(pluginResult) {
console.log('peripheralManagerDidUpdateState: '+ pluginResult.state);
};
cordova.plugins.locationManager.setDelegate(delegate);
// Verify the platform supports transmitting as a beacon
cordova.plugins.locationManager.isAdvertisingAvailable()
.then(function(isSupported){
if (isSupported) {
cordova.plugins.locationManager.startAdvertising(beaconRegion)

}
function BleconOff(){
cordova.plugins.locationManager.stopAdvertising()
.fail(console.error)
.done();
}
return app;
})();
app.initialize();
对于这两个代码，都在目标的后台功能中检查了位置更新和后台获取.另外，两个播放列表上都添加了隐私-始终使用位置描述"
for both codes , the location updates and background fetch are checked in the background capabilities for the target. Also , Privacy - Location Always Usage Description is added on both playlists
推荐答案
不幸的是，Apple在iOS的后台阻止了作为信标传输的功能.实际上，所有CoreBluetooth标准广告都被阻止了，因为广告位是一种有限的资源，在后台使用多个应用程序会很快耗尽该资源.
Unfortunately, Apple blocks the ability to transmit as a beacon in the background on iOS. All CoreBluetooth standard advertisements are actually blocked, because advertising slots are a limited resource and multiple apps in the background would exhaust this resource quickly.
Apple确实有一个专有的备份系统，用于在后台播发蓝牙服务，该系统使用特殊的溢出区域来包含服务标识符.但是，尽管该方案适用于在后台广播蓝牙服务，但不适用于广告信标，因为它破坏了格式.
Apple does have a proprietary backup system for advertising Bluetooth services in the background that uses a special overflow area to include the service identifiers. But while this scheme works for advertising Bluetooth services in the background, it does not work for advertising beacons, because it breaks the format.
底线:iOS上的背景信标广告不起作用.抱歉.
Bottom line: background beacon advertising on iOS just does not work. Sorry.
