Can it be done? Opening the wifi settings is possible, but I dont know how to connect to a specific wifi network.
this code:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"prefs:root=WIFI"]];
opens the iPhone wifi settings dialog. Is there any way to compose the URL name? For example
"prefs:root="WIFI&path=wifi_name"...
This is possible inside an app, but I believe it is not allowed by Apple guidelines. You should be detecting if there is a networking connection either via WWAN or WiFi or if you can connect to a specific host via a URL. Please see Apple Reachability code for the full implementation for the Reachability code produced by Apple. So this is already done for you.
I wouldn't expect this to be possible because of the security risks invovled. Imagine an app that messes with your WiFi settings without your knowledge and permission.

I have an app, in which the user can initiate a short, asynchronous download to access data on the internet, and then the app displays that data. The app is not yet released, but I have tested it on both simulator and several physical devices. On none of them, however, I can locate the app inside the settings menu where I could, for instance, restrict its network access to WiFi only, etc.
I assumed that if my app accesses the internet, it would automatically appear in the settings menu, but apparently it is not so. Am I doing something wrong? What is the process to allow the user to access such basic settings?
I use XCode 10.3, and probram in Objective-C.
If the problem is that there's not a settings entry for your app, please keep in mind that sometimes, in order for an app to be registered, you may need to close your app and the settings app and try opening it again.
If the problem is that you don't see the standard settings for location services, cellular data etc, then you may find maddy's answer here to be helpful: Why is my iOS app forcing a Settings Bundle might be helpful.
Copying the relevant part from this answer:
The iOS 8+ settings page appears […] if the app does any of the
following:
Attempts to access data via a cellular network
Various privacy data
Camera
Microphone
Photo library
Contacts
Location
Notifications
Background data fetch
A settings page may not appear for an app if none of these conditions
have yet been met.
I would required to implement the OSX application online/offline mode.
When internet is available the app icon should online() otherwise the icon should change to offline().
I have implemented checking the internet connection availability(Refered Reachability sample code) but i don't have idea about how to implement online/offline mode like continuously checking the internet connection and update the icons.
Please guide how to achieve the functionality.
I'm testing a feature
that when I can't get wifi connection
I will show a alert view and a button to go to system wifi setting
I know that in IOS6.0 this can't be done
but today I downloaded google map with my Iphone 5(IOS 7.0.6)
If I didn't have Wifi and 3g it will pop out a view
and if I press setting I can go to wifi setting
So I think this feature can be done in IOS 7
Can anyone tell me how to do this??
And Sorry about my poor English!!
No this is not possible, the dialog you are seeing is system dialog saying that if you turn on WiFi you will get a better location fix. As a developer you have no control over these dialogs.
I'm having a problem with my iPad app not bringing up the WiFi authentication when it tries to access the network. When I first open the app and need to connect the panel will show, however if I lock the iPad and come back to it after the WiFi login session has timed out, the panel doesn't display.
Is this something I need to be coding for? My understanding was the panel came up automatically whenever you tried to use the network.
I don't think you can code for it. Probably the user needs to toggle the wifi connection (switch it off and on) to get iOS to reconnect.
I am new to mac os x programming and just got an assignment to write small utility that disable either wireless or wired adapter based on configuration. I was able to disconnect wireless using corewlan framework like :
CWInterface interface = [CWInterface interfaceWithName:#"en1"];
BOOL result = [interface setPower:NO error:&err];
and it is working as expected. I need similar code to disable/disconnect ethernet adapter. I researched that ifconfig (as mentioned below can be used):
sudo ifconfig en0 down
but it require admin password and that i don't want to do. Please suggest an alternative programatic way to disable ethernet adapter without root password.
I read that SCNetworkConfiguration can be used but don't know how to use it. Please help.
Thanks
You cannot shut off network interfaces without having admin access (i.e. that's why the padlock is there in the Network Preference Pane). Think of it this way... you would not want non-admin users on any public machine being able to turn off the network arbitrarily.
For my own apps where I also disable Ethernet & WiFi, I have to get privileges to launch a separate tool in order to run stuff from the SystemConfiguration framework as admin.
