NSString *path=[[NSBundle mainBundle] pathForResource:[youSaid text] ofType:#"png" inDirectory:#"Image"];
NSMutableDictionary *dict = [[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]]];
NSLog(#"diccount:%d",[dict count]);
}
}
NSURL *imageurl = [dict objectForKey:[youSaid text]];
//NSLog(#"text:%#",[youSaid text]);
//Getting asset from url
typedef void (^ALAssetsLibraryAssetForURLResultBlock)(ALAsset *asset);
typedef void (^ALAssetsLibraryAccessFailureBlock)(NSError *error);
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
{
ALAssetRepresentation *rep = [myasset defaultRepresentation];
CGImageRef iref = [rep fullResolutionImage];
//Setting asset image to image view according to the image url
[imageview setImage:[UIImage imageWithCGImage:iref]];
youSaid.text = [NSString stringWithFormat:#"%#",imageurl];
};
ALAssetsLibraryAccessFailureBlock failureblock = ^(NSError *myerror)
{
NSLog(#"Error, cant get image - %#",[myerror localizedDescription]);
};
ALAssetsLibrary *assetLibrary=[[ALAssetsLibrary alloc] init];
[assetLibrary assetForURL:imageurl resultBlock:resultblock failureBlock:failureblock];
UIImage *image=[[UIImage alloc]initWithContentsOfFile:path];
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", 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.

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
