Question

当我在自定义单元格中使用自定义类名创建静态视图时;它的工作对我来说很好。我在我的MainViewController中使用CircularProgressView类作为自定义类。但我想动态地创建UIVIEW，它代表相同。如果您有任何想法，请建议我。

谢谢

看看这个.. A Closer Look at Table View Cells

从上面链接中提取的示例。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

    static NSString *CellIdentifier = @"ImageOnRightCell";

    UILabel *mainLabel, *secondLabel;
    UIImageView *photo;
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
        cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;

        mainLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 0.0, 220.0, 15.0)];
        mainLabel.tag = MAINLABEL_TAG;
        mainLabel.font = [UIFont systemFontOfSize:14.0];
        mainLabel.textAlignment = UITextAlignmentRight;
        mainLabel.textColor = [UIColor blackColor];
        mainLabel.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        [cell.contentView addSubview:mainLabel];

        secondLabel = [[UILabel alloc] initWithFrame:CGRectMake(0.0, 20.0, 220.0, 25.0)];
        secondLabel.tag = SECONDLABEL_TAG;
        secondLabel.font = [UIFont systemFontOfSize:12.0];
        secondLabel.textAlignment = UITextAlignmentRight;
        secondLabel.textColor = [UIColor darkGrayColor];
        secondLabel.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        [cell.contentView addSubview:secondLabel];

        photo = [[UIImageView alloc] initWithFrame:CGRectMake(225.0, 0.0, 80.0, 45.0)];
        photo.tag = PHOTO_TAG;
        photo.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
        [cell.contentView addSubview:photo];
    } else {
        mainLabel = (UILabel *)[cell.contentView viewWithTag:MAINLABEL_TAG];
        secondLabel = (UILabel *)[cell.contentView viewWithTag:SECONDLABEL_TAG];
        photo = (UIImageView *)[cell.contentView viewWithTag:PHOTO_TAG];
    }
    NSDictionary *aDict = [self.list objectAtIndex:indexPath.row];
    mainLabel.text = [aDict objectForKey:@"mainTitleKey"];
    secondLabel.text = [aDict objectForKey:@"secondaryTitleKey"];
    NSString *imagePath = [[NSBundle mainBundle] pathForResource:[aDict objectForKey:@"imageKey"] ofType:@"png"];
    UIImage *theImage = [UIImage imageWithContentsOfFile:imagePath];
    photo.image = theImage;

    return cell;
}

如何在XCODE中动态地使用自定义类在自定义单元格中设置UIVIEW？
