ScratchView

简单封装刮奖效果

使用说明

###安装 #####手工导入 将项目目录下的ScratchView导入项目中 #####Pod安装

pod 'ScratchView', '~> 1.0'

###使用

1. 导入头文件

   #import "SIScratchView.h"

2. 添加需要遮挡的View

   UIImageView *imageView = [[UIImageView alloc]initWithFrame:CGRectMake(75,100, 150, 250) ];
   imageView.contentMode = UIViewContentModeScaleAspectFill ;
   imageView.image = [UIImage imageNamed:@"1"] ;
   imageView.clipsToBounds = YES ;
   [self.view addSubview:imageView] ;

3. 设置遮罩层View

   //自定义覆盖view
   UIView *coverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 150, 250)];
   coverView.backgroundColor = [UIColor greenColor];

4. 初始化ScratchView并添加遮罩层

   // 初始化
   - (SIScratchView *)scratchView {
    	if (_scratchView == nil) {
       	_scratchView = [[SIScratchView alloc] initWithFrame:CGRectMake(75, 100, 150, 250)];
       	_scratchView.maxPathCount = 30;
       	_scratchView.pathWidth = 50.0;
       	_scratchView.pathCount = 6 ;
       	_scratchView.scratchViewDelegate = self ;
   	}
   	return _scratchView;
   }
   
   // 添加
   [self.scratchView setCoveredView:coverView];
   [self.view addSubview:self.scratchView];

   其中属性的含义如下:

    /// 路径的宽度
    @property (nonatomic,assign) CGFloat pathWidth ;
   
    /// 行以及列的路径数,如果设置为3总共会分成3*3个块
    @property (nonatomic,assign) NSUInteger pathCount ;
   
    /// 最大路径数,经过多少块自动消失
    @property (nonatomic,assign) NSUInteger maxPathCount ;
   
    /// 被覆盖的View
    @property (nonatomic,strong) UIView *coveredView ;
   
    /// 代理
    @property (nonatomic,weak) id<SIScratchViewDelegate>scratchViewDelegate ;
   

5. 实现代理方法

   #pragma mark --- SIScratchViewDelegate
   - (void)scratchViewDidOpen:(SIScratchView *)scratchView{
   	NSLog(@"%s",__func__) ;
   }
