iphone - how to get the external ip in objective c -

-

I've seen to get some code will help me IP to connect with iphone.

; (NSString *) getIPAddress {NSString * n = @ "error" - 

 : I find structure ifaddrs * interfaces A = NULL; Structure ifaddrs * temp_addr = NULL; Completed success = 0; // current interface to retrieve - return 0 Success Success = getifaddrs (& amp; Interface); If (success == 0) {// loop interface temp_addr interface via the linked list =; While (temp_addr = Zero!) {If (temp_addr-> saa_addr-> sa_family == AF_INET) {// Check the interface en0 which is the WiFi connection on the iPhone if ([[NSString stringWithUTF8String: temp_addr- & gt; ifa_name] isEqualToString: @ "en0"]) go NSString from {// C string address = [NSString stringWithUTF8String: inet_ntoa (((struct sockaddr_in *) temp_addr- & gt; ifa_addr) - & gt; sin_addr)]; }} Temp_addr = temp_addr- & gt; Ifa_next; }} // free memory Frifaders (interface); Return address; }   
 But the problem is that he receives the IP 10.0.0.1  
 There is an article about obtaining external IP.  
 Thanks   
 
 
 Using the easiest way to get your internet IP address from code is.  
 You can use the URL: or  
 simply parse the return data and you have an external IP address.

qt - switch/case statement in C++ with a QString type -

-
I want to use switch-case in my program but the compiler generates an error. How can I use the switch statement with QString ? The compiler gives me this error: The expression of the switch type 'QString' is invalid My code is as follows : boolStopWord (the word QString) {bool flag = false; Switch (word) {case "the": flag = true; break ; "On" case: flag = true; break ; Case "in": flag = true; break ; Case "your": flag = true; break ; Case "near": flag = true; break ; Case "all": flag = true; break ; Case "this": flag = true; break ; } Return flag; } How do I use the switch statement with a Caststring ? You can not use the switch statement in C ++ language with integral or enum types. You can formally enter the square type of object in the switch statement, but this means that the compiler will look for a user-defined conversion to convert it to an integral or enum type.
