[英]How to detect from an iPhone app whether the battery is in charging or not?
In my iPhone app, there is a requirement to know whether the iPhone is charging or not?在我的 iPhone 应用程序中,需要知道 iPhone 是否正在充电?
If it is charging then I want to display alert for the same.如果它正在充电,那么我想显示相同的警报。
So how can I detect whether the iPhone is charging or not?那么如何检测 iPhone 是否正在充电呢?
[[UIDevice currentDevice] setBatteryMonitoringEnabled:YES];
if ([[UIDevice currentDevice] batteryState] != UIDeviceBatteryStateUnplugged) {
//Device is connected (charging or fully charged)
}
Edit: If you relly want to check if the device is charging (and not 100% full yet), use the UIDeviceBatteryStateCharging
constant in the if statement.编辑:如果您真的想检查设备是否正在充电(尚未 100% 充满电),请在 if 语句中使用UIDeviceBatteryStateCharging
常量。 See the documentation for more information.有关更多信息,请参阅文档。
