iOS开发-手机相册图片选择与预览

照片多选、预览、代理回调

项目需要、自行封装，特此分享。

注意点：对于一千张以上甚至更多的图片待检测显示效果。点击所有图片All Photos、图片能否在collectionView上显示，待检测。

效果图如下：

photo.png collection.jpg single.jpg

how to use

1.导入头文件
#import "ZCJImagesViewController.h"
#import "ZCJSelectImageViewController.h"

//2.遵守代理  ZCJSelectImageViewControllerDelegate

   imagesCtr.delegate = self;

   UINavigationController *navigation =    [[UINavigationControlleralloc]initWithRootViewController:imagesCtr];

   [self presentViewController:navigation animated:YES completion:nil];
