How to save Capture image from camera in IPhone device Photo Library?

I m working on one of the project in which I have to save the captured image in IPhone Device Photo library.

What I want to ask how to implement this through code.Here below I m pasting my codes开发者_如何学Python :--

-(void)imagePickerController:(UIImagePickerController *) picker didFinishPickingMediaWithInfo:(NSDictionary *)info {

[picker dismissModalViewControllerAnimated:YES];
imageView.image = [info objectForKey:@"UIImagePickerControllerOriginalImage"];
imgglobal =imageView.image;
NSString *newFilePath = [NSHomeDirectory() stringByAppendingPathComponent: @"~/Users/abc/Library/Application Support/iPhone Simulator/User/Applications/SAVE_IMAGE_TEST1.JPG"]; 
NSData *imageData = UIImageJPEGRepresentation(imageView.image, 1.0);
NSData  *data = imageData;
if (imageData != nil) {
    [imageData writeToFile:newFilePath atomically:YES];
}
if ([[NSFileManager defaultManager] createFileAtPath:@"~/Users/abc/Library/Application Support/iPhone Simulator/User/Applications/SAVE_IMAGE_TEST1.JPG" contents:data attributes:nil])
{
    UIAlertView *successAlert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Image was successfully saved to the Photo Library." delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
    [successAlert show];
    [successAlert release];
} else {
    UIAlertView     *failureAlert = [[UIAlertView alloc] initWithTitle:@"Failure" message:@"Failed to save image to the Photo Library." delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
    [failureAlert show];
    [failureAlert release];
}       

}

But my application show failure alert please send me the right code to save the captured image into the Iphone device Photo library.

Thanks in Advance its very urgent

It's a one-liner (not counting error processing). Just call UIImageWriteToSavedPhotosAlbum().
