概要

IOS獲取設(shè)備信息一般是經(jīng)由過程UIDevice,UIScreen,NSBundle,NSLocal等方法，如不雅說要獲取設(shè)備的內(nèi)存、處理器信息，似乎可以按照Unix獲取類似信息方法。
UIDevice供給了多種屬性、類函數(shù)及狀況通知，包含檢測電池電量和定位設(shè)備與鄰近感應(yīng)，UIDevice所做的工作就是為應(yīng)用法度榜樣供給用戶及設(shè)備的一些信息。UIDevice類還可以或許收集關(guān)于設(shè)備的各類具體細節(jié)，例如機型及iOS版本等。個中大年夜部分屬性都對開辟工作具有積極的幫助感化
