Hello fellow ios coders. I hope someone can be of help about this part. I'm working on a app with a friend of mine. Who is one of our testers, but I'm fed up by sending the ipa all the time. I readed things about this before and last night I was about to set this up, what I readed from an post wireless distribution So I end up with the following: Code: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>My Cool app</title> </head> <body> <ul> <li><a href="http://192.168.2.46/ios.mobileprovision"> Install Provisioning File</a></li> <li><a href="itms-services://?action=download-manifest&url=http%3A%2F%2F192.168.2.46%2FmyApp.plist"> Install myApp Application</a></li> </ul> </body> </html> As you see I'm doing this right on my own local network. However my iPhone 5S gives me an error when I follow the install myApp application link: Cannot install applications because the certificate for 192.168.2.46 is not valid. What is this error about, and how can I fix this?
