APP跳到系统设置

 //定位服务设置界面
 NSURL *url = [NSURL URLWithString:@"prefs:root=LOCATION_SERVICES"];
 if ([[UIApplication sharedApplication] canOpenURL:url])
 {
     [[UIApplication sharedApplication] openURL:url];
 }

 //蓝牙设置界面
    NSURL *url = [NSURL URLWithString:@"prefs:root=Bluetooth"];
    if ([[UIApplication sharedApplication] canOpenURL:url])
    {
       [[UIApplication sharedApplication] openURL:url];
    }

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

参数配置

看到这几个例子，大家有没有发现，想跳到哪个设置界面只需要prefs:root=后面的值即可！是的，就是这样的。

我在网上找到一个列表，可以跳到这些界面的参数配置：

About — prefs:root=General&path=About
Accessibility — prefs:root=General&path=ACCESSIBILITY
Airplane Mode On — 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

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

当然了需要在info里面设置

在项目中的info.plist中添加 URL types 并设置一项URL Schemes为prefs，如下图：
