{
    // 当前 View 转成图片
    UIImage *image = [self snapshotImage:self.view];
    NSArray *activityItems = @[image];
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
    activityVC.completionWithItemsHandler = ^(UIActivityType  _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {
        if (activityType == UIActivityTypeSaveToCameraRoll) {
            // 保存到相册后，可以给个提示
        }
    };
    [self presentViewController:activityVC animated:YES completion:nil];

    NSString *path = [[NSBundle mainBundle] pathForResource:@"video2_cover" ofType:@"png"];
    NSURL *url = [NSURL fileURLWithPath:path];
    
    NSArray *activityItems = @[url];
    UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
    activityVC.completionWithItemsHandler = ^(UIActivityType  _Nullable activityType, BOOL completed, NSArray * _Nullable returnedItems, NSError * _Nullable activityError) {
        if (activityType == UIActivityTypeSaveToCameraRoll) {
            // 保存到相册后，可以给个提示
