刮刮乐效果

    ScrachViewController *scratchViewController =[[ScrachViewControlleralloc] initWithNibName:@"ScratchViewClear"bundle:nil];

    

    

    scratchViewController.view.frame = self.view.frame;

    

    [selfpresentModalViewController:scratchViewController animated:YES];

//    [scratchViewController loadScratchPaperWithPath:@"ss"];

    [scratchViewController loadScratchPaperWithUrl:@"http://a.hiphotos.baidu.com/album/w%3D2048/sign=0a938b00d53f8794d3ff4f2ee6230cf4/faedab64034f78f06fe0f24b78310a55b2191c9a.jpg"];

}

 

 

 

然后再调用第三方的五个文件就行了。
