Ios 不推荐使用库方法

这是不推荐的，更新的代码可能是什么

 ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];
    [library assetForURL:referenceURL resultBlock:^(ALAsset *asset) {
        ALAssetRepresentation *rep = [asset defaultRepresentation];

使用以下代码从“多媒体资料”中获取所有图片： 首先，您需要导入照片框架

#import <Photos/Photos.h>

您可以从以下代码中检索图像：

PHImageRequestOptions *requestOptions = [[PHImageRequestOptions alloc] init];
requestOptions.synchronous = YES;

PHImageManager *manager = [PHImageManager defaultManager];
[manager requestImageForAsset:YOUR_ARRAY[INDEX_ARRAY][@"assest"]
                   targetSize:CGSizeMake(self.view.frame.size.width/3, 200)
                  contentMode:PHImageContentModeDefault
                      options:requestOptions
                resultHandler:^void(UIImage *image, NSDictionary *info) {
                    YOUR_IMAGE_VIEW.image = image;
                }];

看到了吗？整个框架都被弃用了。使用

Photos.framework

非常感谢，明白了。

PHImageRequestOptions *requestOptions = [[PHImageRequestOptions alloc] init];
requestOptions.synchronous = YES;

PHImageManager *manager = [PHImageManager defaultManager];
[manager requestImageForAsset:YOUR_ARRAY[INDEX_ARRAY][@"assest"]
                   targetSize:CGSizeMake(self.view.frame.size.width/3, 200)
                  contentMode:PHImageContentModeDefault
                      options:requestOptions
                resultHandler:^void(UIImage *image, NSDictionary *info) {
                    YOUR_IMAGE_VIEW.image = image;
                }];
