给大家分享自己在写权限SDK中的一个意外收获。
在代码中调用如下代码：
NSURL*url = [NSURL URLWithString:@"prefs:root=WIFI"];
[[UIApplication sharedApplication] openURL:url];
即可跳转到设置页面的对应项。
About — prefs:root=General&path=About //关于本机
MICROPHONE-- prefs:root=Privacy&path=MICROPHONE //麦克风
CONTACTS --- prefs:root=Privacy&path=CONTACTS //通讯录
Accessibility — prefs:root=General&path=ACCESSIBILITY //辅助功能
Airplane Mode On — prefs:root=AIRPLANE_MODE //飞行模式
Auto-Lock — prefs:root=General&path=AUTOLOCK //自动锁定
Brightness — prefs:root=Brightness //自动锁定
Bluetooth — prefs:root=General&path=Bluetooth //蓝牙
Date & Time — prefs:root=General&path=DATE_AND_TIME //日期和时间
FaceTime — prefs:root=FACETIME //
General — prefs:root=General
Keyboard — prefs:root=General&path=Keyboard
iCloud — prefs:root=CASTLE
iCloud Storage & Backup — prefs:root=CASTLE&path=STORAGE_AND_BACKUP

Location Services — prefs:root=LOCATION_SERVICES //定位服务
Music — prefs:root=MUSIC
Music Equalizer — prefs:root=MUSIC&path=EQ
Music Volume Limit — prefs:root=MUSIC&path=VolumeLimit

Safari — prefs:root=Safari
Siri — prefs:root=General&path=Assistant
Sounds — prefs:root=Sounds
Software Update — prefs:root=General&path=SOFTWARE_UPDATE_LINK
Store — prefs:root=STORE
Twitter — prefs:root=TWITTER
Usage — prefs:root=General&path=USAGE
VPN — prefs:root=General&path=Network/VPN
Wallpaper — prefs:root=Wallpaper
Wi-Fi — prefs:root=WIFI
其实看到这里我们可以有这样的猜想，首先把手机的系统修改为英文语言。如图所示
可以很清楚苹果是如何来找到系统中设置对应的功能。
IOS9之后无法使用上面方法跳转，请使用
NSURL*url = [NSURLURLWithString:@"App-Prefs:root=Privacy"];
[[UIApplicationsharedApplication]openURL:[NSURLURLWithString:UIApplicationOpenSettingsURLString]options:@{}completionHandler:^(BOOLsuccess) {
}];
