    NSMutableDictionary *dict开发者_StackOverflow社区 = [[NSMutableDictionary alloc] init];
    for (int i=0 ; i<[assets count]; i++) {         
        if (i<[dictWords count]) {          
            [dict setObject:[[[assets objectAtIndex:i] defaultRepresentation] url] forKey:[NSString stringWithFormat:@"%@",[dictWords objectAtIndex:i]]];

NSFileManager *fileManager = [NSFileManager defaultManager];//create instance of NSFileManager


NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it

NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory

NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", youSaid.text]]; //add our image to the path

[fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the image

NSLog(@"image saved");
}

@end

This is the following code i wrote but i am not able to save images.i am only able to sane an image known as NULL.png .please suggest the changes to save all the pics in my library to bundle.

Thanks, Christy

Sample Code

    - (void) openPhotoLibrary {
        NSLog(@"openPhotolibrary");

        if ([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]) {
            if (self.picker != nil) {
                NSLog(@"releasing self.picker...");
                [self.picker release];
            }
            self.picker = [[UIImagePickerController alloc] init];
            self.picker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
            //self.picker.allowsImageEditing = YES;
            [self.picker presentModalViewController:self.picker animated:YES];
            self.picker.delegate = self;

            [[[CCDirector sharedDirector] openGLView] addSubview:self.picker.view];
        }
    }

    - (void)imagePickerControllerDidCancel:(UIImagePickerController *)currentPicker {
        NSLog(@"imagePickerControllerDidCancel");

        // hide the self.picker if user cancels picking an image.
        [currentPicker dismissModalViewControllerAnimated:YES];
        self.picker.view.hidden = YES;
        [self.picker.view removeFromSuperview];
    }

    - (void)imagePickerController:(UIImagePickerController *)currentPicker didFinishPickingImage:(UIImage *)image editingInfo:(NSDictionary *)editingInfo
    {
        [self saveImage:image withImageName:@"myPhoto"];

    }

//saving an image

- (void)saveImage:(UIImage*)image withImageName:(NSString*)imageName {

NSData *imageData = UIImagePNGRepresentation(image); //convert image into .png format.

NSFileManager *fileManager = [NSFileManager defaultManager];//create instance of NSFileManager

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); //create an array and store result of our search for the documents directory in it

NSString *documentsDirectory = [paths objectAtIndex:0]; //create NSString object, that holds our exact path to the documents directory

NSString *fullPath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@"%@.png", imageName]]; //add our image to the path

[fileManager createFileAtPath:fullPath contents:imageData attributes:nil]; //finally save the path (image)

NSLog(@"image saved");

}

This code its working for me try it may be its helps you

-(IBAction)PhotoLibraryButtonClicked:(id)sender{
if([UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypePhotoLibrary]){


    imagePicker.sourceType = UIImagePickerControllerSourceTypePhotoLibrary;
    [self presentModalViewController:imagePicker animated:YES];

}
else{

    [self displaysorceError];

    }

}


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

//[self.popoverrcontroller dismissPopoverAnimated:true];
//[popoverrcontroller release];

NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType];
[self dismissModalViewControllerAnimated:YES];

if([mediaType isEqualToString:(NSString *)kUTTypeImage]){

    UIImage *image = [info objectForKey:UIImagePickerControllerOriginalImage];
//  UIImage *rote = [image rotateInDegrees:219.0f];

    img.image = image;
    if(newMedia)
        UIImageWriteToSavedPhotosAlbum(image, nil,nil, nil);
}else if([mediaType isEqualToString:(NSString *)kUTTypeImage]){

    //not available vidio
}
}


-(IBAction)saveImageIn:(id)sender{

NSData *imageData = UIImagePNGRepresentation(img.image);

NSFileManager *fileMan = [NSFileManager defaultManager];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullPathToFile = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:@" %d.png",img.image]];

[fileMan createFileAtPath:fullPathToFile contents:imageData attributes:nil];



UIAlertView *alt = [[UIAlertView alloc] 
                    initWithTitle:@"Thank You" 
                    message:@"Image Save In Directory" 
                    delegate:nil cancelButtonTitle:@"OK" 
                    otherButtonTitles:nil];
[alt show];
[alt release];
}

thank you..:)Neet
