IOS 獲取手機裝置資訊

回顧一下，Android中獲取手機裝置相關資訊：通過android.os.Build、context.getResources().getDisplayMetrics()、Settings.Secure.getString(context.getContentResolver(), Settings.Secure.ANDROID_ID)、(TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE)等等，從而獲取到手機裝置：手機型號、手機品牌、裝置名、手機系統、螢幕寬高等等一系列資訊，其中還涉及到許可權問題。

相對IOS，則是從開發庫中獲取裝置相關資訊：通過UIDevice、NSLocale、UIScreen、CTTelephonyNetworkInfo等等，從而獲取到手機裝置：裝置名稱、系統名稱、系統版本、螢幕寬高等等一系列資訊，但需要通過指定的開發庫才能獲取得到。

此處需要匯入部分開發庫：

注：獲取裝置model中systemInfo.machine裝置資訊獲取是相對較為完善且全面的，若後續有新的裝置新增，請從 Models - The iPhone Wiki 上進行續補；Apple對於獲取MAC相對嚴格控制，一般是獲取不到的。
