Installation

CocoaPods

你可以通过 CocoaPods 来安装.执行以下一段话即可.

pod "UPCardsCarousel"

Manual

Simply copy the folder UPCardsCarousel to your project and import it in XCode.

你只需要将UPCardsCarousel文件夹复制到你的项目中即可.

Usage

Start by importing the header file:

一开始,先引入头文件:

#import "UPCardsCarousel.h"

Now, you can create a UPCardsCarousel object by giving it a frame:

然后,你可以创建出UPCardsCarousel实体,然后给定一个frame值:

UPCardsCarousel *carousel = [[UPCardsCarousel alloc] initWithFrame:aFrame];

Then you need to assign to it:

之后,你需要设定代理以及给代理提供数据:

• a delegate object that conforms to the UPCardsCarouselDelegate protocol
• a dataSource object that conforms to the UPCardsCarouselDataSource protocol

Data Source

The data source informs the carousel about the total number of cards and the content of each card through two self-explanatory methods:

数据源是给carousel提供有多少张卡片,以及每张图片上面的内容:

• - (NSUInteger)numberOfCardsInCarousel:(UPCardsCarousel *)carousel (required)
• - (UIView *)carousel:(UPCardsCarousel *)carousel viewForCardAtIndex:(NSUInteger)index (required)

The labels in the banner are given with an optional method. If the data source doesn't implement this method, the label banner will not be displayed.

以下方法是可选方法,用来给卡片提供标题的,如果没有实现,默认是不会显示出来的.

• - (NSString *)carousel:(UPCardsCarousel *)carousel labelForCardAtIndex:(NSUInteger)index (optional)

Delegate

The delegate is optional and will be notified when some events occur:

代理方法是非必须的,用以提示事件发生的时机:

• - (void)carousel:(UPCardsCarousel *)carousel didTouchCardAtIndex:(NSUInteger)index
• - (void)carousel:(UPCardsCarousel *)carousel willDisplayCardAtIndex:(NSUInteger)index
• - (void)carousel:(UPCardsCarousel *)carousel willHideCardAtIndex:(NSUInteger)index
• - (void)carousel:(UPCardsCarousel *)carousel didDisplayCardAtIndex:(NSUInteger)index
• - (void)carousel:(UPCardsCarousel *)carousel didHideCardAtIndex:(NSUInteger)index

Methods

Method	Description
reloadData	Reloads the carousel data and recreates the visible cards and moves to the top of the cards deck
reloadDataWithCurrentIndex:(NSUInteger)index	Reloads the carousel data and recreates the visible cards and moves to the specified index in the cards deck
reloadNumberOfCards	Reloads only the number of cards in the carousel and doesn't change the visible cards
reloadCardAtIndex:(NSUInteger)index	Recreates the card at the specified index
cardAtIndex:(NSUInteger)index	Return the card view at the specified index

Customization

Cards Deck

Usually, the carousel will not display all the cards supplied by the data source at once. It will handle a infinite scrolling process by destroying and creating cards at both ends. The number of visible cards is given and can be customized through the following property:

通常情况下,carousel不会一下子显示出所有的图片.他有重用机制,并支持无限滑滚.可见的卡片数由以下方法提供:

• maxVisibleCardsCount (default is 6)

You can customize the duration of the card movement between the hidden deck and the visible deck, with this property:

你可以定制每张卡片的移动时间,默认是0.4秒:

• movingAnimationDuration (defaut is 0.4 seconds)

By default, the carousel will return to the top of the deck when making a double-tap on the first hidden card.

默认情况下,双击carousel会返回第一张显示的图片.

You can disable this behaviour by setting the doubleTapToTop property to NO.

你可以禁用双击功能.

Labels Banner

You can customize the text font and color of the banner through these two methods:

你可以通过以下两个方法来定制横幅:

• - (void)setLabelFont:(UIFont *)font (default is system font)
• - (void)setLabelTextColor:(UIColor*)color (default is [UIColor blackColor])

You can choose between two locations for the banner through the labelBannerPosition property:

你可以通过labelBannerPosition属性来设置位移值:

• UPCardsCarouselLabelBannerLocation_bottom - the banner will be located below the cards deck (default)
• UPCardsCarouselLabelBannerLocation_top - the banner will be located above the cards deck

Finally, you also have access to the banner view object through the labelBanner property so you can customize it as you want.

当然,你也可以写你自己的横幅view.给labelBanner赋值即可.
