Picture does not show in iCarousel

Question

I am using the iCarousel to display my image, but strangely I did the codes right and nothing appears. I am trying to display image from the directory folder. In the directory folder I have few folders that have image saved in it. Is there something missing? I am almost there and I can't do it. Also I have one warning at the last parenthesis of UIView saying control reaches end of non-void function. Does this have something to do with this problem? I have put the return and it does not work. This is my code below.

-(void)viewDidLoad
{
    [super viewDidLoad];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSFileManager *fileManager  = [NSFileManager defaultManager];

    //configure carousel1
    NSString *fPath = [documentsDirectory stringByAppendingPathComponent:@"Tops"];
    NSArray *directoryContent = [fileManager directoryContentsAtPath: fPath];
    imageArray1 = [directoryContent mutableCopy];

    //configure carousel2
    fPath = [documentsDirectory stringByAppendingPathComponent:@"Bottoms"];
    directoryContent = [fileManager directoryContentsAtPath:fPath];
    imageArray2 = [directoryContent mutableCopy];

    carousel1.type = iCarouselTypeLinear;
    carousel2.type = iCarouselTypeLinear;
}

- (void)viewDidUnload
{
    [super viewDidUnload];

    //free up memory by releasing subviews
    self.carousel1 = nil;
    self.carousel2 = nil;
}

edit the code in - (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view method as mentioned below --

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view {
if (view == nil)
{
    view = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 200.0f, 200.0f)];

    UIImage *image;
    if (carousel == carousel1)
    {
        image  = [UIImage imageWithContentsOfFile:[imageArray1 objectAtIndex:index]];
        ((UIImageView *)view).image = image;
    }
    else
    {
        image  = [UIImage imageWithContentsOfFile:[imageArray2 objectAtIndex:index]];
        ((UIImageView *)view).image = image;
    }
        return view;
}
else {
    UIImage *image;
    if (carousel == carousel1)
    {
        image  = [UIImage imageWithContentsOfFile:[imageArray1 objectAtIndex:index]];
        ((UIImageView *)view).image = image;
    }
    else
    {
        image  = [UIImage imageWithContentsOfFile:[imageArray2 objectAtIndex:index]];
        ((UIImageView *)view).image = image;
    }
}


return view;
}

may be the problem is with your code where if (view != nil) then your code doesn't have implementation of setting image for view in icarousel.
