【问题描述】：

我想在我的应用中更改专辑名称。

if ([collection canPerformEditOperation:PHCollectionEditOperationRename]  == YES)
    
        //rename localizedTitle
    

如果是“是”，我想更改名称。

我的代码是：

PHFetchOptions *userAlbumsOptions = [PHFetchOptions new];
userAlbumsOptions.predicate = [NSPredicate predicateWithFormat:@"estimatedAssetCount > 0"];

PHFetchResult *userAlbums = [PHAssetCollection fetchAssetCollectionsWithType:PHAssetCollectionTypeAlbum subtype:PHAssetCollectionSubtypeAny options:userAlbumsOptions];

[userAlbums enumerateObjectsUsingBlock:^(PHAssetCollection *collection, NSUInteger idx, BOOL *stop)
 

 ];

【参考方案1】：

-(void)changeAlbumtitle:(PHAssetCollection *)collection withTitle:(NSString *)title 

    if (![collection canPerformEditOperation:PHCollectionEditOperationRename]) 

        NSLog(@"can't PerformEditOperation");
        return;
    


    [[phphotoLibrary sharedPhotoLibrary] performChanges:^
        PHAssetCollectionChangeRequest *changeTitlerequest =[PHAssetCollectionChangeRequest changeRequestForAssetCollection:collection];
        changeTitlerequest.title = title;


     completionHandler:^(BOOL success, NSError *error) 
        NSLog(@"Finished editing collection. %@", (success ? @"Successfully." : error));
    ];

在上面给函数传递专辑对象（PHAssetCollection）和标题

首先检查 PHAssetCollection 可以执行重命名的函数 编辑操作

如果可以进行编辑操作，则执行 PHAssetCollectionChangeRequest 并设置新标题。
