picture does not show up using iCarousel

Question

I am using MultiCarousel in a storyboard and I am getting errors and can not display the image in the carousel. Is there a problem with the code??I am getting errors from viewfromItemAtIndex saying
expected method body
expected':'
expected identifier or (
expected identifier or (
extraneous closing brace ("}")
Please feel free to ask for more code if you want to see a specific part.

#import "iCarouselExampleViewController.h"


@interface iCarouselExampleViewController ()

@property (nonatomic, retain) NSMutableArray *items1;
@property (nonatomic, retain) NSMutableArray *items2;

@end


@implementation iCarouselExampleViewController

@synthesize carousel1;
@synthesize carousel2;
@synthesize items1;
@synthesize items2;
- (void)awakeFromNib
{
    //set up data sources
    self.items1 = [NSMutableArray array];
    for (int i = 0; i < 100; i++)
    {
        [items1 addObject:[NSNumber numberWithInt:i]];
    }

    self.items2 = [NSMutableArray array];
    for (int i = 65; i < 65 + 58; i++)
    {
        [items2 addObject:[NSString stringWithFormat:@"%c", i]];
    }
}

- (void)dealloc
{
    //it's a good idea to set these to nil here to avoid
    //sending messages to a deallocated viewcontroller
    carousel1.delegate = self;
    carousel1.dataSource = self;
    carousel2.delegate = self;
    carousel2.dataSource = self;

You were actually really close. You were missing the very first brace in the beginning of the method. In the future, Xcode will point you to a location at least near the error which you can use as a starting point to analyze your code. Always make sure to count and balance opening and closing braces, brackets, and parens.

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{ // <--- This brace was missing!!
    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]];
