How to get IP Address in iOS

Long time .... sorry for being not available since long. Life you know.... hahahaha !

So, i was looking for some solution to find IP Address in iOS , and to be very frank , i found codes that are useless now with iOS 7, 8 and 9 in market.

I tried NSHost also, but not so appealing to me either.

Here is something i found from anonymous developer, he shared it as a block of code, i created a function, which you my fellow developers, can copy and paste and it will return you the IP.

Simple as it is.....i still remember my promise...Pure code no talks ;)


-(NSString *) getIPforDevice{
    NSUInteger  an_Integer;
    NSArray * ipItemsArray;
    NSString *externalIP;
    NSURL *iPURL = [NSURL URLWithString:@""];
    if (iPURL) {
        NSError *error = nil;
        NSString *theIpHtml = [NSString stringWithContentsOfURL:iPURL
        if (!error) {
            NSScanner *theScanner;
            NSString *text = nil;
            theScanner = [NSScanner scannerWithString:theIpHtml];
            while ([theScanner isAtEnd] == NO) {
                // find start of tag
                [theScanner scanUpToString:@"<" intoString:NULL] ;
                // find end of tag
                [theScanner scanUpToString:@">" intoString:&text] ;
                // replace the found tag with a space
                //(you can filter multi-spaces out later if you wish)
                theIpHtml = [theIpHtml stringByReplacingOccurrencesOfString:
                             [ NSString stringWithFormat:@"%@>", text]
                                                                 withString:@" "] ;
                ipItemsArray =[theIpHtml  componentsSeparatedByString:@" "];
                an_Integer=[ipItemsArray indexOfObject:@"Address:"];
                externalIP =[ipItemsArray objectAtIndex:  ++an_Integer];
        } else {
            NSLog(@"Oops... g %d, %@"
                  [error code], 
                  [error localizedDescription]);
    return externalIP;


Always feel free to ask any queries....

Happy Programming...
