如何获取 iPhone 的电池状态？

Answer 1

UIDevice *myDevice = [UIDevice currentDevice];
[myDevice setBatteryMonitoringEnabled:YES];
float batLeft = [myDevice batteryLevel];
int i=[myDevice batteryState];

int batinfo=(batLeft*100);

NSLog(@"Battry Level is :%d and Battery Status is :%d",batinfo,i);

switch (i)
{
    case UIDeviceBatteryStateUnplugged:
    {
        [BCStatus setText:NSLocalizedString(@"UnpluggedKey", @"")];
        break;
    }
    case UIDeviceBatteryStateCharging:
    {
        [BCStatus setText:NSLocalizedString(@"ChargingKey", @"")];
        break;
    }
    case UIDeviceBatteryStateFull:
    {
        [BCStatus setText:NSLocalizedString(@"FullKey", @"")];
        break;
    }
    default:
    {
        [BCStatus setText:NSLocalizedString(@"UnknownKey", @"")];
        break;
    }
}

BCStatus 是 uilabel。
