獲取當(dāng)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攒霹。

它返回的是0.00-1.00之間的浮點(diǎn)值。? 另外, -1.00表示模擬器。

但是仔細(xì)觀察它的返回值, ?是以0.05遞變的蛛芥。折算成100% 也就是以5%來遞變的纱烘。

也就是說,很不精確曲楚。

下面方法幢痘。相當(dāng)精確, 誤差保持在1%以內(nèi)裂七。

我們知道, Mac下有個(gè)IOKit.framework庫皆看。它可以計(jì)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(gè)Mac下的工程, 找到IOKit.framework背零，那IOKit.framework里面的IOPowerSources.h和IOPSKeys.h拷貝到你的iOS項(xiàng)目中腰吟。另外, 還需要把IOKit也導(dǎo)入到你的工程中去。(請(qǐng)使用真機(jī)調(diào)試)
