SDPhotoBrowser的用法,处理点击显示图片

首先看下效果吧,首先这是新浪微博的cell中图片视图,点击图片后让它显示高清大图

在PictureView视图中遵守代理方法"SDPhotoBrowserDelegate"

好了,直接上使用方法吧 首先导入SDPhotoBrowser的框架,直接拉到项目中

在PictureView视图中遵守代理方法"SDPhotoBrowserDelegate"

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{
    SDPhotoBrowser *browser = [[SDPhotoBrowser alloc] init];

    //设置容器视图,父视图

    browser.sourceImagesContainerView = self;

    browser.currentImageIndex = indexPath.item;

    browser.imageCount = self.pictureInfos.count;

    //设置代理

    browser.delegate = self;

    //显示图片浏览器

    [browser show];
}
复制代码

- (NSURL *)photoBrowser:(SDPhotoBrowser *)browser highQualityImageURLForIndex:(NSInteger)index
{
    WBPictureInfo *picInfo = self.pictureInfos[index];

    //拿到显示的图片的高清图片地址

    NSURL *url = [NSURL URLWithString:picInfo.bimiddleImage];

    return url;
}
复制代码

返回占位图片

- (UIImage *)photoBrowser:(SDPhotoBrowser *)browser placeholderImageForIndex:(NSInteger)index
{
    NSIndexPath *indexPath = [NSIndexPath indexPathForItem:index inSection:0];

    WBPictureCell *cell = (WBPictureCell *)[self cellForItemAtIndexPath:indexPath];

    return cell.imageView.image;
}
复制代码

没错就是这么的简单,搞定了!
