自定义说明

支持自定义卡牌样式，继承YFLDragCardView类，并重写- (void)YFLDragCardViewLayoutSubviews 方法，在该方法里布局子视图即可。

示例代码

YFLDragConfigure *configure = [[YFLDragConfigure alloc]init];
configure.visableCount = 3;
configure.containerEdge = 10.0f;
configure.cardEdge = 5.0f;
configure.cardCornerRadius = 10.0f;
configure.cardCornerBorderWidth = 0.45f;
configure.cardBordColor = [UIColor colorWithRed:176.0f/255.0f green:176.0f/255.0f blue:176.0f/255.0f alpha:1];
self.container = [[YFLDragCardContainer alloc]initWithFrame:CGRectMake(0, 100, ScreenWidth, 400) configure:configure];
self.container.dataSource = self;
self.container.delegate = self;
[self.view addSubview:self.container];
[self.container reloadData];

或者默认初始化方法
self.container = [[YFLDragCardContainer alloc]initWithFrame:CGRectMake(0, 100, ScreenWidth, 400)];
self.container.dataSource = self;
self.container.delegate = self;
[self.view addSubview:self.container];
[self.container reloadData];

数据源方法

- (NSInteger)numberOfRowsInYFLDragCardContainer:(YFLDragCardContainer *)container
{
   return self.data.count;
}
- (YFLDragCardView *)container:(YFLDragCardContainer *)container viewForRowsAtIndex:(NSInteger)index
{ 
   return [YFLDragCardView new];
}

代理方法

- (void)container:(YFLDragCardContainer *)container didSelectRowAtIndex:(NSInteger)index
{
    NSLog(@"didSelectRowAtIndex :%ld",(long)index);
}
- (void)container:(YFLDragCardContainer *)container dataSourceIsEmpty:(BOOL)isEmpty
{
   // TO  DO
}
- (BOOL)container:(YFLDragCardContainer *)container canDragForCardView:(YFLDragCardView *)cardView
{
   return YES;
}
- (void)container:(YFLDragCardContainer *)container dargingForCardView:(YFLDragCardView *)cardView direction:(ContainerDragDirection)direction widthRate:(float)widthRate  heightRate:(float)heightRate
{
  // TO DO
}
- (void)container:(YFLDragCardContainer *)container dragDidFinshForDirection:(ContainerDragDirection)direction forCardView:(YFLDragCardView *)cardView
{
    NSLog(@"disappear:%ld",(long)cardView.tag);
}
