Here is my Table's Custom Cell code :

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    VideoListCustomCell *cell = (VideoListCustomCell *)[self.tableView dequeueReusableCellWithIdentifier:@"VideoListCustomCell"];
    //if(cell == nil)    {
        NSArray* nib = [[NSBundle mainBundle] loadNibNamed:@"VideoListCustomCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
        cell.showsReorderControl = NO;
        cell.selectionStyle = UITableViewCellSelectionStyleNone;
        cell.backgroundColor=[UIColor clearColor];
        [cell drawImageView];

        [cell.btnLike addTarget:self action:@selector(btnLikeClick:) forControlEvents:UIControlEventTouchUpInside];
        [cell.btnComment addTarget:self action:@selector(btnCommentClick:) forControlEvents:UIControlEventTouchUpInside];
        [cell.btnOther addTarget:self action:@selector(btnOtherClick:) forControlEvents:UIControlEventTouchUpInside];
        [cell.btnUserImage addTarget:self action:@selector(btnUserImageClick:) forControlEvents:UIControlEventTouchUpInside];
        [cell.btnUserName addTarget:self action:@selector(btnUserNameClick:) forControlEvents:UIControlEventTouchUpInside];
        [cell.btnVideo addTarget:self action:@selector(btnVideoClick:) forControlEvents:UIControlEventTouchUpInside];
    //}

    VideoShare *shareObj = [arrVideos objectAtIndex:indexPath.row];

    [cell.btnUserName setTitle:shareObj.vdUserName forState:UIControlStateNormal];

Answer 1

在init方法的VideoListCustomCell中添加按钮。

Answer 2

您可以尝试使用：UIButton * obj = [UIButton alloc] init];
