iOS如何跳转到各个系统设置界面

APP需要用到的权限有时候没有打开，就需要提示用户打开某项权限，最好是直接引导用户跳转到对应的设置界面。下面是一些直接跳转到设置界面的方法。

1、定位

 //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];
}

2、墙纸

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

3、蓝牙

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

4、iCloud

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

总结起来就是想要跳到哪个设置界面，就打开prefs:root=对应的设置界面的值。
　　　　这个在iOS6，7和8中确实可以跳转，只是还少了一个步骤。在URL Types中添加一个新项。某没有深入研究，只填写prefs就可以了。
