Question

当我将NSCollectionViewItem拖到Finder时，我正在开发一个将文件复制到Finder的函数，所以我实现了以下委托：

- (BOOL)collectionView:(NSCollectionView *)cv writeItemsAtIndexes:(NSIndexSet *)indexes toPasteboard:(NSPasteboard *)pasteboard
{

    NSMutableArray *urls = [NSMutableArray array];
    [indexes enumerateIndexesUsingBlock:^(NSUInteger idx, BOOL *stop)
     {
         NSDictionary *dictionary = [[cv content] objectAtIndex:idx];
         [urls addObject:[dictionary objectForKey:KEY_URL]];
     }];

    if ([urls count] > 0)
    {
        [pasteboard clearContents];
        BOOL result = [pasteboard writeObjects:urls];
        return result;
    }
    return NO;
}

或者这样：

- (BOOL)collectionView:(NSCollectionView *)cv writeItemsAtIndexes:(NSIndexSet *)indexes toPasteboard:(NSPasteboard *)pasteboard
{

    NSMutableArray *urls = [NSMutableArray array];
    [indexes enumerateIndexesUsingBlock:^(NSUInteger idx, BOOL *stop)
     {
         NSDictionary *dictionary = [[cv content] objectAtIndex:idx];
         [urls addObject:[[dictionary objectForKey:KEY_URL] path]];
     }];

    [pasteboard declareTypes:@[NSFilenamesPboardType] owner:self];
    [pasteboard setPropertyList:urls forType:NSFilenamesPboardType];

    return YES;
}

他们都很好。

现在我真的想获得其他功能的拖动目标网址。有人可以帮我解决一下吗？

您可以尝试：

- （BOOL）collectionView：（NSCollectionView *）cv writeItemsAtIndexes：（NSIndexSet *）索引toPasteboard：（NSPasteboard *）粘贴板 {

NSMutableArray *urls = [NSMutableArray array];
[indexes enumerateIndexesUsingBlock:^(NSUInteger idx, BOOL *stop)
 {
     NSDictionary *dictionary = [[cv content] objectAtIndex:idx];
     [urls addObject:[[dictionary objectForKey:KEY_URL] path]];
 }];

[pasteboard clearContents];

return [pasteboard writeObjects:urls];

}
