Question

这是我无法回答/解决的问题的扩展。所以我决定尝试使用复制和粘贴命令来解决这种情况。但是，当我尝试复制所选的图像时，它不允许我粘贴它，菜单不会弹出以允许粘贴，只有复制出现，我认为这意味着它不会复制到粘贴板。我就是这样的地方：

- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath
{

    NSString *file = stickers2[indexPath.item];

    NSLog (@"%d",indexPath.item);
    NSLog (@"%@ FILE STRING",file);
    NSString *sticker = [file stringByReplacingOccurrencesOfString:@".png" withString:@""];
    NSLog (@"%@ STICKER STRING",sticker);

        imageItem = [UIImage imageNamed:sticker];
    NSError* error = nil;
    UIPasteboard *pb = [UIPasteboard generalPasteboard];
    NSString *imagePath = [[NSBundle mainBundle] pathForResource:sticker ofType:@"png"];

    NSLog(@"%@ IS THE IMAGE PATH!", imagePath);
    NSData *data = [NSData dataWithContentsOfFile:imagePath options:0 error: &error];
    [pb setData:data forPasteboardType:@"public.jpeg"];

    if (data == nil)
    {
        NSLog(@"Failed to read file, error %@", error);
    }


    NSLog(@"%@", pb);
    NSLog(@"%@",data);


    if (delegate != nil) [delegate didSelectSticker:sticker];{
        NSLog(@"HAHHAHHA");
    };
    NSLog (@"%@",file);

    [self dismissViewControllerAnimated:YES completion:nil];
}

的NSLog：
