項目中經(jīng)常需要我們?nèi)カ@取一些系統(tǒng)的權(quán)限俭厚，可是如果用戶在剛開始的時候并沒有允許一些要求，后期不做提示的話颤诀，可能只能去設(shè)置中一個個去找尋了辙喂，所以我們就需要常常去跳轉(zhuǎn)設(shè)置頁面去打開一些權(quán)限開關(guān)。這里就簡單的介紹一下哟沫。
首先需要跳轉(zhuǎn)方法：
ios10以前: [[UIApplication sharedApplication]openURL:@""];
ios10:[[UIApplication sharedApplication]openURL:@"" options:nil completionHandler:nil];
這個是需要做判斷的饺蔑，如果不判斷可能就會崩潰。
然后就是在URL Schemes 添加 prefs的url
然后就是用上面的方法去跳轉(zhuǎn)了：
以前就是枚舉的設(shè)置的一些關(guān)鍵字：
