instead of converting image in to Gif apple provide UIImageView.animationImages proparty that you can Animation Number of images one by one like gif. like Bellow code:-

UIImage *statusImage = [UIImage imageNamed:@"status1.png"];
    YourImageView = [[UIImageView alloc]
                                      initWithImage:statusImage];


    //Add more images which will be used for the animation
    YourImageView.animationImages = [NSArray arrayWithObjects:
                                         [UIImage imageNamed:@"status1.png"],
                                         [UIImage imageNamed:@"status2.png"],
                                         [UIImage imageNamed:@"status3.png"],
                                         [UIImage imageNamed:@"status4.png"],
                                         [UIImage imageNamed:@"status5.png"],
                                         [UIImage imageNamed:@"status6.png"],
                                         [UIImage imageNamed:@"status7.png"],
                                         [UIImage imageNamed:@"status8.png"],
                                         [UIImage imageNamed:@"status9.png"],
                                         nil];




         //setFrame of postion on imageView

          YourImageView.frame = CGRectMake(
                                     self.view.frame.size.width/2
                                     -statusImage.size.width/2, 
                                     self.view.frame.size.height/2
                                     -statusImage.size.height/2, 
                                     statusImage.size.width, 
                                     statusImage.size.height);


  YourImageView.center=CGPointMake(self.view.frame.size.width /2, (self.view.frame.size.height)/2);


      YourImageView.animationDuration = 1;
      [self.view addSubview:YourImageView];

Thanks Nitin but in my project i am working to save the image and i don't want animation on the view i would rather upload the gif image on my servers using webservices — naughty, Jun 08 '13 at 06:46

First of all you should check for your problem in Apple Documentation. Everything is given there. What you need is to Research & Read.

You should try the ImageIO framework. It can convert .png files into CGImageRef objects and then export the CGImageRefs to .gif files.

To save Images to Photo Library :UIImageWriteToSavedPhotosAlbum(imageToSave, nil, nil, nil); Also Documented in UIKit.

Just one more thing vin here i am saving with the path NSString *path = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject] stringByAppendingPathComponent:@"animated.gif"]; what's the path for gallery as this is saved in the documents folder – naughty Jun 08 '13 at 07:02
@naughty : What do you mean by "gallery" ? – Bhavin Jun 08 '13 at 07:03
the picturegallery folder used where all the pictures are saved when we click from camera or photos in iphone – naughty Jun 08 '13 at 07:04
@naughty : `UIImageWriteToSavedPhotosAlbum(imageToSave, nil, nil, nil);` – Bhavin Jun 08 '13 at 07:07
Iam using something like CGImageDestinationSetProperties(destination, (CFDictionaryRef)gifProperties); CGImageDestinationFinalize(destination); CFRelease(destination); to save the gif image and if i save the image using UIImageWriteToSavedPhotosAlbum it would save a still image – naughty Jun 08 '13 at 07:11
@naughty : Take a look at : http://developer.apple.com/library/ios/#documentation/UIKit/Reference/UIKitFunctionReference/Reference/reference.html – Bhavin Jun 08 '13 at 07:13
