//第一种:iCarousel(多种类型)需要关闭ARC

- (void)viewDidLoad {

[super viewDidLoad];

//导入需要的第三方库中的iCarousel.h头文件

//创建对象

carousel = [[iCarousel alloc]initWithFrame:self.view.bounds];

//设置数据源和代理实现两个协议方法

}

//切换按钮的绑定方法

- (void)ButtonTouched {

//获取type枚举类型可用数字代替

inttype = carousel.type;

//用三目运算法判断==必须的

type = (type == iCarouselTypeCoverFlow2) ? iCarouselTypeLinear : (type + 1) ;

//赋值type

carousel.type = type;

}

#pragma mark --- iCarouselDataSource, iCarouselDelegate

//返回有多少个展示项

- (NSUInteger)numberOfItemsInCarousel:(iCarousel *)carousel {
