How to get device IPAddess in iPhone SDK?

 Hello friends,
Here is the code which helps to get the Local IPAddress of an iOS device.

#include <arpa/inet.h>
#include <netdb.h>
#include <net/if.h>
#include <ifaddrs.h>


// retun the host name
+ (NSString *) hostname
{
    char baseHostName[256];
    int success = gethostname(baseHostName, 255);
    if (success != 0) return nil;
    baseHostName[255] = '\0';
   
#if !TARGET_IPHONE_SIMULATOR
    return [NSString stringWithFormat:@"%s.local", baseHostName];
#else
     return [NSString stringWithFormat:@"%s", baseHostName];
#endif
}

// return IP Address
+ (NSString *) localIPAddress
{
    struct hostent *host = gethostbyname([[self hostname] UTF8String]);
    if (!host) {herror("resolv"); return nil;}
    struct in_addr **list = (struct in_addr **)host->h_addr_list;
    return [NSString stringWithCString:inet_ntoa(*list[0]) encoding:NSUTF8StringEncoding];
}

How to rotate a view in iPhone using QuartzCore.framework?

Hi,
Code regarding the rotation. you can use the below code for simply making rotation to any angle you want. You can also reverse the animation that you want. You need to import "QuartzCore.framework" into your code.

   CABasicAnimation *theAnimation;
    theAnimation=[CABasicAnimation animationWithKeyPath:@"transform.rotation"];
    theAnimation.duration=1.0; // Animation duration
    theAnimation.repeatCount=1; // no of times you want to do animation
    theAnimation.autoreverses=YES; // reverses the animation
    theAnimation.fromValue=[NSNumber numberWithFloat:0.0]; // initial stage of animation
    theAnimation.toValue=[NSNumber numberWithFloat:degreesToRadians(360)]; // rotation angle
    [self.view.layer addAnimation:theAnimation forKey:@"animateRotation"]; // add animation to the
 layer of a view for which you want animation.
