* 这是一个使用起来非常简单的开源库，自带下载缓存，不会造成循环引用，不用考虑定时器不会销毁（我都已经帮你做好了）
* 如果使用过程中有任何问题，可以联系我，我会第一时间回复你，然后尽我的努力把这个库维护的更好，更简单方便的使用。
* 谢谢支持，如果喜欢，请给我个star。

# **轮播组件：JYCarousel**
**开源库名称：** **JYCarousel**
**开源库当前版本：** **0.0.3**
**开源库简介：** 这是一个使用起来非常简单的开源轮播库，自带下载和缓存，不会造成循环引用，不用考虑定时器不会销毁（我都已经帮你做好了）。
## **1. 轮播库引用方式**
- **1.直接下载工程，把包含源代码的文件夹JYCarousel引入工程即可使用**
- **2.支持cocoapods。当前版本0.0.2 在Podfile文件中添加以下文字即可：**
```
pod 'JYCarousel', '~> 0.0.3'
```
## **2. 轮播基本原理**
使用三个imageView添加到ScrollView，始终保持中间的imageView在可视界面里。当前的imageView滚动到下一个imageView，然后把下一个imageView滚动到三个imageView的中心位置，在这过程中赋值的时候是三个imageView同时赋值，滚动的时候找到最中间的imageView，把这个imageView的tag值设置为当前的索引，滚动完成后把这个imageView设置为中心滚动位置。
比如三张图A、B、C。要做的scrollview实际上应该是五张的大小顺序是C、A、B、C、A。初始偏移量设置到第二张，监听scrollview滑动事件。判断偏移量。当偏移量在第一张时将偏移量修改到第四张，当偏移量在第五张时将偏移量调整到第二章。这样在循环时比较流畅，才能无缝无限循环滚动
## **3. 轮播的特性**
- **无缝循环轮播，处理的很好，不会显得生硬**
- **自带图片下载和缓存，不依赖任何第三方，引入即可使用，不用任何配置**
- **支持block方式和delegate方式,使用起来巨方便**
- **随时根据需要清除缓存**
- **采用disk缓存，不会占用app内存，释放你的app内存**
- **可以随时更新轮播数据，完美切换,**
- **用户可自定义的属性多，具体见配置文件JYConfiguration**
## **4. 代码文件结构和功能**
**JYCarousel**
- **JYCarousel**
- 作用：轮播组件的创建和开始
- **JYConfiguration**
- 作用：轮播组件的自定义配置，配置你想要的效果
- **JYPageControl**
- 作用：轮播组件的指示器样式
- **JYTitleLabel**
- 作用：标签的样式
- **JYWeakTimer**
- 作用：轮播组件的弱引用定时器，解决NSTimer不能销毁的问题
- **UIImageView+JYImageViewManager**
- 作用：imageView请求网络图片的分类
- **JYImageDownloader**
- 作用：请求网络图片
- **JYImageCache**
- 作用：网络图片的缓存
## **5. 轮播组件的使用**
#### **提供两个初始化方法：**
```
/**
block方式回调初始化
@param frame frame
@param configBlock 轮播属性配置
@param clickBlock 点击回调
@return carousel
*/
- (instancetype)initWithFrame:(CGRect)frame
configBlock:(CarouselConfigurationBlock)configBlock
clickBlock:(CarouselClickBlock)clickBlock;
/**
delegate方式回调初始化
@param frame frame
@param configBlock 轮播属性配置
@param target delegate
@return carousel
*/
- (instancetype)initWithFrame:(CGRect)frame
configBlock:(CarouselConfigurationBlock)configBlock
target:(id<JYCarouselDelegate>)target;
```
#### **使用举例：**
##### **1.block回调方式创建：**
```
- (void)addCarouselView1{
//block方式创建
__weak typeof(self) weakSelf = self;
NSMutableArray *imageArray = [[NSMutableArray alloc] initWithArray: @[@"1.jpg",@"2.jpg",@"3.jpg",@"4.jpg"]];
if (!_carouselView1) {
_carouselView1= [[JYCarousel alloc] initWithFrame:CGRectMake(0, 0, SCREEN_WIDTH, 100) configBlock:^JYConfiguration *(JYConfiguration *carouselConfig) {
carouselConfig.pageContollType = RightPageControl;
carouselConfig.interValTime = 3;
return carouselConfig;
} clickBlock:^(NSInteger index) {
[weakSelf clickIndex:index];
}];
[self.view addSubview:_carouselView1];
}
//开始轮播
[_carouselView1 startCarouselWithArray:imageArray];
}
```
##### **2.delegate回调方式创建：**
```
//遵循协议
@interface SubViewController ()<JYCarouselDelegate>
//创建
- (void)addCarouselView2{
NSMutableArray *imageArray2 = [[NSMutableArray alloc] initWithArray: @[@"http://p1.bqimg.com/524586/894925a41a745ba8.jpg",@"http://p1.bqimg.com/524586/edd59898ac21642f.jpg",@"http://p1.bqimg.com/524586/d277aa654cd60c3d.jpg",@"http://p1.bqimg.com/524586/a49b8d3e1b953f25.jpg",@"http://p1.bqimg.com/524586/972bff3b7a5fb7e1.jpg"]];
NSMutableArray *titleArray2 = [[NSMutableArray alloc] initWithArray: @[@"http://p1.bqimg.com/524586/894925a41a745ba8.jpg",@"http://p1.bqimg.com/524586/edd59898ac21642f.jpg",@"http://p1.bqimg.com/524586/d277aa654cd60c3d.jpg",@"http://p1.bqimg.com/524586/a49b8d3e1b953f25.jpg",@"http://p1.bqimg.com/524586/972bff3b7a5fb7e1.jpg"]];
if (!_carouselView2) {
_carouselView2 = [[JYCarousel alloc] initWithFrame:CGRectMake(0, 120, SCREEN_WIDTH, 100) configBlock:^JYConfiguration *(JYConfiguration *carouselConfig) {
carouselConfig.pageContollType = MiddlePageControl;
carouselConfig.pageTintColor = [UIColor whiteColor];
carouselConfig.currentPageTintColor = [UIColor redColor];
carouselConfig.placeholder = [UIImage imageNamed:@"default"];
carouselConfig.faileReloadTimes = 5;
carouselConfig.textAlignment = NSTextAlignmentLeft;
carouselConfig.pageContollType = LabelPageControl;
return carouselConfig;
} target:self];
[self.view addSubview:_carouselView2];
}
//开始轮播
[_carouselView2 startCarouselWithArray:imageArray2 titleArray:titleArray2];
}
//回调方法
- (void)carouselViewClick:(NSInteger)index{
NSLog(@"代理方式你点击图片索引index = %ld",index);
//清楚缓存数据 可以在app启动的时候清楚上一次轮播缓存,根据自己需要
[[JYImageCache sharedImageCache] jy_clearDiskCaches];
}
```
## **6. 缓存机制**
- 启动时可设置超时自动清除缓存功能
```
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
//添加以下方法即可
//每次启动时，检查是否超时，清除缓存(单位是小时这里是10分钟)
[[JYImageCache sharedImageCache] jy_clearDiskCachesWithTimeout:10.0/60];
}
```
- 手动清除缓存
```
//清除缓存数据 根据自己需要调用
[[JYImageCache sharedImageCache] jy_clearDiskCaches];
```
## **7. 注意事项**
内存得不到释放造成内存泄露，使用循环引用了。请注意使用。看下面在block回调处，对Self是使用弱引用的，不然内存是得不到释放的。
<pre>
// 请使用weakSelf，不然内存得不到释放
__weak typeof(self) weakSelf = self;
//图片数组（或者图片URL，图片URL字符串，图片UIImage对象）
NSMutableArray *imageArray = [[NSMutableArray alloc] initWithArray: @[@1.jpg,@2.jpg,@3.jpg,@4.jpg]];
JYCarousel *carouselView = [[JYCarousel alloc] initWithFrame:CGRectMake(0, 64, ViewWidth(self.view), 100) configBlock:nil clickBlock:NSInteger index {
//点击imageView回调方法
[weakSelf clickIndex:index];
}];
//开始轮播
[carouselView startCarouselWithArray:imageArray];
[self.view addSubview:carouselView];
</pre>
## **8. 版本更新日志**
- 添加启动超时自动清除缓存功能
- 添加titlLabel标签
- 去除切换动画
## **喜欢就给个Star吧！**
