ios - 调整单元格字段 - objective-c

Question

我有一个动态设置 table view controller用于填充新闻类型提要。我在将一个类连接到另一个类以设置当前单元格的文本、图像等时遇到问题。

这里是要点:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"timelineCell";

    FBGTimelineCell *cell = (FBGTimelineCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    cell.text = [self.googlePlacesArrayFromAFNetworking[indexPath.row] objectForKey:@"message"]; <!-- here is where I want to for example, set the title to the message within this array.
    if (!cell)
    {
        cell = [[FBGTimelineCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        [cell setSelectionStyle:UITableViewCellSelectionStyleNone];
        [cell initTimelineCell];
    }

    UIImage *img = [UIImage imageNamed:[NSString stringWithFormat:@"%d.jpg", indexPath.row]];
    cell.photoView.image = img;
    return cell;
}

这是 FBH... init功能:

- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
    self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
    if (self) {

        // Initialization code
        cellContentView = [[UIView alloc] initWithFrame:CGRectMake(10, 5, 300, 440)];
        cellContentView.backgroundColor = [UIColor whiteColor];

        photoView = [[FBGTimelinePhotoView alloc] initWithFrame:CGRectMake(5, 102, 310, 310)];
        photoView.backgroundColor = [UIColor darkGrayColor];
        [photoView setUserInteractionEnabled:YES];

        UIView *profilePic = [[UIView alloc] initWithFrame:CGRectMake(9, 9, 30, 30)];
        profilePic.backgroundColor = [UIColor darkGrayColor];

        UILabel *usernameLabel = [[UILabel alloc] initWithFrame:CGRectMake(45, 9, 222, 18)];
        usernameLabel.font = [UIFont systemFontOfSize:14.0];
        usernameLabel.text = @"Username";

        UILabel *timestampLabel = [[UILabel alloc] initWithFrame:CGRectMake(45, 25, 222, 17)];
        timestampLabel.font = [UIFont systemFontOfSize:12.0];
        timestampLabel.text = @"3 hours ago";
        timestampLabel.textColor = [UIColor lightGrayColor];

        UILabel *statusLabel = [[UILabel alloc] initWithFrame:CGRectMake(9, 50, 283, 41)];
        statusLabel.font = [UIFont systemFontOfSize:15.0];
        statusLabel.text = @"Status..status..status..status..status..status..status..status..status..status..status..status..status..status..status..";
        statusLabel.numberOfLines = 2;
        statusLabel.lineBreakMode = NSLineBreakByWordWrapping;

        UILabel *likeLabel = [[UILabel alloc] initWithFrame:CGRectMake(9, 413, 32, 21)];
        likeLabel.font = [UIFont systemFontOfSize:13.0];
        likeLabel.text = @"Like";

        UILabel *commentLabel = [[UILabel alloc] initWithFrame:CGRectMake(113, 413, 74, 21)];
        commentLabel.font = [UIFont systemFontOfSize:13.0];
        commentLabel.text = @"Comment";

        UILabel *shareLabel = [[UILabel alloc] initWithFrame:CGRectMake(246, 413, 46, 21)];
        shareLabel.font = [UIFont systemFontOfSize:13.0];
        shareLabel.text = @"Share";

        [self addSubview:cellContentView];
        [self addSubview:photoView];
        [cellContentView addSubview:profilePic];
        [cellContentView addSubview:usernameLabel];
        [cellContentView addSubview:timestampLabel];
        [cellContentView addSubview:statusLabel];
        [cellContentView addSubview:likeLabel];
        [cellContentView addSubview:commentLabel];
        [cellContentView addSubview:shareLabel];


    }
    return self;
}

所以我需要能够在 cellForRowAtIndexPath 中的单元格内设置单元格文本和不同 View 如果可能，对于 FB..init 中设置的每个单元格功能。

建议、想法？

您应该为每个需要在 cellFroRowAtIndexPath 中访问的 UI 元素创建属性(在 FBGTimelineCell 类中)，然后您可以使用 cell.propertyName 访问它们。
