Answer 1

serverIP is textField. You can get the text in it as serverIp.text
So you can save it in user default as

[[NSUserDefaults standardUserDefaults] setObject:serverIp.text forKey:@"save"];

You were trying to save the text field itself as integer in user defaults, which is incorrect.

To retrieve it, use

NSString *serverIpString = [[NSUserDefaults standardUserDefaults] objectForKey:@"save"];
