獲取當前剩余電量, 我們通常采用上述方法即蘋果官方文檔提供的。
它返回的是0.00-1.00之間的浮點值。? 另外, -1.00表示模擬器。
但是仔細觀察它的返回值, ?是以0.05遞變的。 折算成100% 也就是以5%來遞變的。
也就是說,很不精確。
下面方法。相當精確, 誤差保持在1%以內。
我們知道, Mac下有個IOKit.framework庫。 它可以計算出我們需要的電量。
如果我們要使用它的話, （iOS是不提供的） 可以先建立一個Mac下的工程, 找到IOKit.framework，那IOKit.framework里面的IOPowerSources.h和IOPSKeys.h拷貝到你的iOS項目中。另外, 還需要把IOKit也導入到你的工程中去。(請使用真機調試)
