界面滑动 颜色跟随渐变

项目介绍：

1. – (void)viewDidLoad {
2. [super viewDidLoad];
4. [self dataInit];
6. [self createUI];
8. //两种初始化方式 根据类型
9. //1.
10. /** 渐变色对象设置 确保 collectionView对象存在
11. colorDataArr 存在并且数组里存放对象为 UIColor*/
12. self.colorChange = [[WJColorChange alloc]initWithType:SingleColor];
13. [self.colorChange settingScrollView:self.showCollectionView colorArray:self.colorDataArr needChangeColorView:self.showCollectionView];
15. //2.
16. /** 渐变色对象设置
17. colorDataArr 存的数组里放的是 颜色数组对象 颜色数组里存放对象为 UIColor*/
18. self.colorChange = [[WJColorChange alloc]initWithType:TransverseGradientColor];
19. [self.colorChange settingArrayScrollView:self.showCollectionView colorArray:self.colorDataArr needChangeColorView:self.view];
