我正在尝试使用以下代码将 iCarousel 添加到现有项目中，但出现此错误：MemberCatalog[14990:1a903] -[MainViewController carousel:viewForItemAtIndex:reusingView:]: unrecognized selector sent to instance 0xa0589b0.

iCarousel.m 中抛出错误的行是：view = [_dataSource carousel:self viewForItemAtIndex:index reusingView:[self dequeueItemView]];

任何帮助都会非常感激。 

carouselItems = [NSArray arrayWithObjects:
         [UIImage imageNamed:@"iLibrary+Featured_AM-RAH.png"],
         [UIImage imageNamed:@"iLibrary+Featured_CCA.png"],
         [UIImage imageNamed:@"iLibrary+Featured_GI-PA.png"],
         nil];

// Initialize and configure the carousel
    carousel = [[iCarousel alloc] initWithFrame:self.view.bounds];
    carousel.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
    carousel.type = iCarouselTypeCoverFlow2;
carousel.delegate = self;
carousel.dataSource = self;

    [self.view addSubview:carousel];

- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index
{
    UIImage *image = [carouselItems objectAtIndex:index];
    UIButton *button = [[[UIButton alloc] initWithFrame:CGRectMake(0, 0, image.size.width, image.size.height)] autorelease];
    [button setBackgroundImage:image forState:UIControlStateNormal];
    [button setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
    button.titleLabel.font = [button.titleLabel.font fontWithSize:50];
    button.tag=index;
    return button;

}

您正在实现一个-carousel:viewForItemAtIndex:方法，但视图需要一个-carousel:viewForItemAtIndex:reusingView:方法。

你需要用reusingView:(UIView *)view参数更新你的方法，你会没事的。您还应该使用该可重用视图，而不是分配越来越多的视图，但这是另一回事。
