iOS开发实战：获取手机电量

话不多说，直接上代码

- (NSString*)NativeToolPublicGetDeviceBatteryString{

    //打开电池的监听

    [UIDevice currentDevice].batteryMonitoringEnabled = YES;

    //获取剩余电量 范围在0.000000 至 1.000000之间

    CGFloat batterylevel = [UIDevice currentDevice].batteryLevel;

    floatlevel = batterylevel *100;

    return [NSString stringWithFormat:@"%.2f",level];

}
