label=[[UILabel alloc]initWithFrame:CGRectMake(0, 280, 145, 50)]; label.opaque=YES; label.hidden=YES; label.textColor=[UIColor whiteColor]; label.backgroundColor=[UIColor clearColor]; label.font=[UIFont boldSystemFontOfSize:20]; label.textAlignment=UITextAlignmentCenter; [self addSubview:label]; do this in AFItemView class in - (id)initWithFrame:(CGRect)frame class — Rama Rao, Feb 16 '12 at 09:36
I have done with the lable, my app is crashing at [coverImageName setObject:coverView.imageName forKey:coverNumber];with crash report , '-[__NSCFDictionary setObject:forKey:]: attempt to insert nil value (key: 0)' — Youngwing, Feb 16 '12 at 09:42
arey yar u have to pass the image name from the CoverFlowViewController class na?see below answer.U have to change the method name as - (void)setImage:(UIImage *)image forIndex:(int)index named:(NSString*)imageName; from - (void)setImage:(UIImage *)image forIndex:(int)index; in AFOpenFlowView class. — Rama Rao, Feb 16 '12 at 09:47
Thanks alot!!! it is working!! I changed - (void)setImage:(UIImage *)image forIndex:(int)index to - (void)setImage:(UIImage *)image forIndex:(int)index named:(NSString *)imageName.... — Youngwing, Feb 16 '12 at 09:58

You simply take a label in method- (id)initWithFrame:(CGRect)frame{} for class AFItemView.m in openflow code and check in the class:AFOpenFlowView.m in method - (void)centerOnSelectedCover:(BOOL)animated{} set text as belowselectedCoverView.label.text=coverImagename;.This worked for me.

Can I know what is coverImagename here? same as my imageName? I have declared property for imageName in my CoverFlowViewController class,but it is nor appearing in AFOpenFlowView.m. – Youngwing Feb 16 '12 at 07:41
@Rama Rao - (void)centerOnSelectedCover:(BOOL)animated { CGPoint selectedOffset = CGPointMake(COVER_SPACING * selectedCoverView.number, 0); coverView=[[CoverFlowViewController alloc]init]; selectedCoverView.lbl.text=coverView.imageName; NSLog(@" here image name is %@",selectedCoverView.lbl.text); [scrollView setContentOffset:selectedOffset animated:animated]; } the log is showing null value,title is not added to image. – Youngwing Feb 16 '12 at 07:52
check the below code:- (void)centerOnSelectedCover:(BOOL)animated { CGPoint selectedOffset = CGPointMake(COVER_SPACING * selectedCoverView.number, 0); NSNumber *coverNumber = [NSNumber numberWithInt:selectedCoverView.number]; NSString *coverImagename=[coverImageName objectForKey:coverNumber]; selectedCoverView.label.text=coverImagename; selectedCoverView.label.hidden=NO; [scrollView setContentOffset:selectedOffset animated:animated]; } – Rama Rao Feb 16 '12 at 07:53
Sorry I didn't get this line, NSString *coverImagename=[coverImageName objectForKey:coverNumber];is coverImageName dictionary? – Youngwing Feb 16 '12 at 08:42

yes.U have to pass like below:`

- (void)setImage:(UIImage *)image forIndex:(int)index named:(NSString*)imageName{
    // Create a reflection for this image.
    UIImage *imageWithReflection = [image addImageReflection:kReflectionFraction];
    NSNumber *coverNumber = [NSNumber numberWithInt:index];
    [coverImages setObject:imageWithReflection forKey:coverNumber];
    [coverImageHeights setObject:[NSNumber numberWithFloat:image.size.height] forKey:coverNumber];
    [coverImageName setObject:imageName forKey:coverNumber];`

    // If this cover is onscreen, set its image and call layoutCover.
    AFItemView *aCover = (AFItemView *)[onscreenCovers objectForKey:[NSNumber numberWithInt:index]];
    if (aCover) {
        [aCover setImage:imageWithReflection originalImageHeight:image.size.height reflectionFraction:kReflectionFraction named:imageName];

        [self layoutCover:aCover selectedCover:selectedCoverView.number animated:NO];
    }
}`

and i pass the image name like below:

for (int i=0; i < 10; i++) {
        imageName = [[NSString alloc] initWithFormat:@"cover_%d.jpg", i];UIImage* image_=[UIImage imageNamed:imageName];
        CGFloat width = 290;
        CGFloat height = 200;

        CGSize newSize=CGSizeMake(width, height);
        [(AFOpenFlowView *)self.view setImage:[self imageWithImage:image_ scaledToSize:newSize] forIndex:i named:imageName];
        [imageName release];
        NSLog(@"%d is the index",i);

    }
    [(AFOpenFlowView *)self.view setNumberOfImages:10];
