例如：跳转到FACEBOOK

        NSURL *url = [NSURL URLWithString:@"prefs:root=FACEBOOK"];
        if ([[UIApplication sharedApplication] canOpenURL:url])
        {
            [[UIApplication sharedApplication] openURL:url];
        }

修改上面url可以直接跳转到指定页面

不会的话把系统调为英文模式 自己慢慢对照吧

• About — prefs:root=General&path=About
• Accessibility — prefs:root=General&path=ACCESSIBILITY
• Airplane Mode On(飞行模式界面 (⊙﹏⊙)b这个就是个坑!) — prefs:root=AIRPLANE_MODE
• Auto-Lock — prefs:root=General&path=AUTOLOCK
• Brightness — prefs:root=Brightness
• Bluetooth — prefs:root=General&path=Bluetooth
• Date & Time — prefs:root=General&path=DATE_AND_TIME
• 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
• International — prefs:root=General&path=INTERNATIONAL
• Location Services — prefs:root=LOCATION_SERVICES
• Music — prefs:root=MUSIC
• Music Equalizer — prefs:root=MUSIC&path=EQ
• Music Volume Limit — prefs:root=MUSIC&path=VolumeLimit
• Network — prefs:root=General&path=Network
• Nike + iPod — prefs:root=NIKE_PLUS_IPOD
• Notes — prefs:root=NOTES
• Notification — prefs:root=NOTIFICATIONS_ID
• Phone — prefs:root=Phone
• Photos — prefs:root=Photos
• Profile — prefs:root=General&path=ManagedConfigurationList
• Reset — prefs:root=General&path=Reset
• Safari — prefs:root=Safari

• Sounds — prefs:root=Sounds
• Software Update — prefs:root=General&path=SOFTWARE_UPDATE_LINK

• 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

跳转到自己应用的设置界面(还有点问题)

NSURL * url = [NSURLURLWithString:UIApplicationOpenSettingsURLString]；
if([[UIApplicationsharedApplication] canOpenURL:url]) {
    NSURL*url =[NSURLURLWithString:UIApplicationOpenSettingsURLString];           [[UIApplicationsharedApplication] openURL:url];  
}

需要请求一下任意权限，才可以跳进自己的app设置里面，如果未请求任何权限，就只能跳到系统的设置界面
