获取当前剩余电量, 我们通常采用上述方法即苹果官方文档提供的。
它返回的是0.00-1.00之间的浮点值。 另外, -1.00表示模拟器。
但是仔细观察它的返回值, 是以0.05递变的。 折算成100% 也就是以5%来递变的。
也就是说,很不精确。
下面方法。相当精确, 误差保持在1%以内。
我们知道, Mac下有个IOKit.framework库。 它可以计算出我们需要的电量。
如果我们要使用它的话, （iOS是不提供的） 可以先建立一个Mac下的工程, 找到IOKit.framework，那IOKit.framework里面的IOPowerSources.h和IOPSKeys.h拷贝到你的iOS项目中。另外, 还需要把IOKit也导入到你的工程中去。(请使用真机调试)
