I want to create OpenVPN connection in my application, can't find any information if it is possible without OpenVPN connection app installed.
Is it possible?
No, it is not possible to create OpenVPN Connect in iOS device without OpenVPN connection app installed.
Hope this helps.
To check if openVPN is installed or not you can use following code which I found from OpenVPN doc
BOOL installed = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:@"openvpn://"]];
