iOS 10之前， 可以通过
在TargetS -> Info ->URL Types 里面设置URL Schemes 为 prefs，并实现如下代码
UIApplication.shared.open(URL(string:"prefs:root=WIFI")!, options: [:]) { (success) in
print("RedirectToWifi: \(success)")
}
来设置不同的prefs 跳转到设置的二级页面(例子中是跳转到Wifi设置页)
但是iOS10以后，官方文档表示:
You can use UIApplicationOpenSettingsURLString
to open your own app's settings (this has been available since iOS 8) but any other prefs:
URL is now considered a private API and use will result in app rejection.
意思就是苹果已经不允许app跳到各个设置页面了，只能用
UIApplication.shared.open(URL(string:UIApplicationOpenSettingsURLString)!, options: [:]) { (success) in
print("RedirectToWifi: \(success)")
}
来跳转到设置页面.
但是如果真的需要跳转到设置页面的话，可以通过如下的方法进行跳转:
UIApplication.shared.open(URL(string:"App-Prefs:root=WIFI")!, options: [:]) { (success) in
print("RedirectToWifi: \(success)")
}
将prefs更改为App-Prefs即可.
But! 不建议这样做哦，
官方文档中说过:
URL is now considered a private API and use will result in app rejection.
虽然是有可能躲过苹果的检测，但是苹果如果发现你这样用了，app上架是有被拒的风险的.

That‘s all.
