CBStoreHouseRefreshControl支持 CocoaPods, 添加以下一行代码到Podfile中即可：
pod "CBStoreHouseRefreshControl"
Alternatively, you can just drag CBStoreHouseRefreshControl (.h .m) and BarItem (.h .m) into your own project.
另一种方式就是：你把 CBStoreHouseRefreshControl (.h .m) 和 BarItem (.h .m) 文件拖到你的项目中就可以了。
How to use it
You can attach it to any UIScrollView like UITableView or UICollectionView using following simple static method:
你可以将它添加到UIScrollView的任何子类当中，用如下的一个方法：
+ (CBStoreHouseRefreshControl*)attachToScrollView:(UIScrollView *)scrollView
target:(id)target
refreshAction:(SEL)refreshAction
plist:(NSString *)plist;
self.storeHouseRefreshControl = [CBStoreHouseRefreshControl attachToScrollView:self.tableView target:self refreshAction:@selector(refreshTriggered:) plist:@"storehouse"];
Or, using this method for more configurable options:
或者用下面的一个方法进行更多的设置：
+ (CBStoreHouseRefreshControl*)attachToScrollView:(UIScrollView *)scrollView
target:(id)target
refreshAction:(SEL)refreshAction
plist:(NSString *)plist
color:(UIColor *)color
lineWidth:(CGFloat)lineWidth
dropHeight:(CGFloat)dropHeight
scale:(CGFloat)scale
horizontalRandomness:(CGFloat)horizontalRandomness
reverseLoadingAnimation:(BOOL)reverseLoadingAnimation
internalAnimationFactor:(CGFloat)internalAnimationFactor;
self.storeHouseRefreshControl = [CBStoreHouseRefreshControl attachToScrollView:self.tableView target:self refreshAction:@selector(refreshTriggered:) plist:@"storehouse" color:[UIColor whiteColor] lineWidth:1.5 dropHeight:80 scale:1 horizontalRandomness:150 reverseLoadingAnimation:YES internalAnimationFactor:0.5];
Then, implement UIScrollViewDelegate in your UIViewController if you haven't already, and pass the calls through to the refresh control:
然后，在你的控制器中实现你的UIScrollViewDelegate的一些方法，你将那些代理方法的值传进去即可：
- (void)scrollViewDidScroll:(UIScrollView *)scrollView
{
[self.storeHouseRefreshControl scrollViewDidScroll];
}
- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate
{
[self.storeHouseRefreshControl scrollViewDidEndDragging];
}
Lastly, make sure you've implemented the refreshAction you passed it earlier to listen for refresh triggers:
最后，确保你实现了刷新的操作：
- (void)refreshTriggered
{
//call your loading method here
//Finshed loading the data, reset the refresh control
[self.storeHouseRefreshControl finishingLoading];
}

How to use your own shape
The CBStoreHouseRefreshControl's shape contains bunch of BarItem for animation, each BarItemis running its own animation, you need to provide startPoint and endPoint through a plist file.
All BarItem will share one coordinate system whose origin is at the top-left corner. For example if you want to draw a square, the plist will look like this:
CBStoreHouseRefreshControl的形状包含了一系列的BarItem用于动画，每一个BarItem都执行他自身的动画，你需要给他们在plist文件里面提供一个起始值和结束值。
所有的BarItem会分享同一个坐标系统，这个坐标系统的原始顶点在左上角。如果你是要绘制一个正方形，那么，plist文件中就应该是如下的样子。
Notes:
Make sure you put the right key which are startPoints and endPoints. 确保你的key值是在正确的起始点与结束点那里
Make sure you are using the right format ({x,y}) for coordinates. 确保你是使用了正确的坐标系统
The highlight/loading animation will highlight each bar item in the same order you declare them in plist, use reverseLoadingAnimation to reverse the animation. 这个高亮效果会根据你的plist文件中列表的顺序而依次高亮，你可以使用reverseLoadingAnimation来反转动画效果
Easy way to generate startPoint and endPoint?
@isaced mentions that it's easier to use PaintCode to generate startPoint and endPoint:
你可以使用PaintCode来生成起始点与结束点
Configuration
Play with following parameters to configure CBStoreHouseRefreshControl's view and animation:
你可以根据如下的一些参数来配置CBStoreHouseRefreshControl的动画效果：
Set the bar color with the color parameter 设置bar的颜色
Set the bar width with the lineWidth parameter 设置bar的宽度以及线宽
Set the height of control with the dropHeight parameter 设置控制器的垂直高度？？？
Set the scale of control with the scale parameter 设置缩放参数
Adjust how disperse the bar items appear/disappear by changing the horizontalRandomnessparameter 调整bar是怎么消失的
Set if reversing the loading animation with the reverseLoadingAnimation parameter, if set to YES, the last bar item will be highlighted firstly. 反转动画的顺序
Adjust the time offset of the appear/disappear animation by changing theinternalAnimationFactor parameter, for example if internalAnimationFactor is 1 all bar items will appear/disappear all together. 调整动画时间的偏移量
