I have figure out your problem. You can do this as below..

-(void)selectedAssets:(NSArray*)_assets {

UIActivityIndicatorView * activityIndicator = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray];
UIViewController * topView = [self.viewControllers objectAtIndex:[self.viewControllers count]-1];
activityIndicator.center = CGPointMake(topView.view.frame.size.width/2, topView.view.frame.size.height/2);
[activityIndicator setHidden:NO];
[topView.view addSubview:activityIndicator];
[topView.view bringSubviewToFront:activityIndicator];
[activityIndicator startAnimating];

[self performSelector:@selector(doProcess:) withObject:_assets afterDelay:2.1];

}

- (void) doProcess:(NSArray *)_assets {

NSMutableArray *returnArray = [[[NSMutableArray alloc] init] autorelease];

for(ALAsset *asset in _assets) {

    NSMutableDictionary *workingDictionary = [[NSMutableDictionary alloc] init];
    [workingDictionary setObject:[asset valueForProperty:ALAssetPropertyType] forKey:@"UIImagePickerControllerMediaType"];
    [workingDictionary setObject:[UIImage imageWithCGImage:[[asset defaultRepresentation] fullScreenImage]] forKey:@"UIImagePickerControllerOriginalImage"];
    [workingDictionary setObject:[[asset valueForProperty:ALAssetPropertyURLs] valueForKey:[[[asset valueForProperty:ALAssetPropertyURLs] allKeys] objectAtIndex:0]] forKey:@"UIImagePickerControllerReferenceURL"];

    [returnArray addObject:workingDictionary];

    [workingDictionary release];    
}

[self popToRootViewControllerAnimated:NO];
[[self parentViewController] dismissModalViewControllerAnimated:YES];

if([delegate respondsToSelector:@selector(elcImagePickerController:didFinishPickingMediaWithInfo:)]) {
    [delegate performSelector:@selector(elcImagePickerController:didFinishPickingMediaWithInfo:) withObject:self withObject:[NSArray arrayWithArray:returnArray]];
}

}
