ios TableView不同的单元格高度

-(CGFloat)tableView:(UITableView *)tableView heightForRowATindexPath:(NSIndexPath *)indexPath {
        UIImage *image = dataModel[indexPath.row];
        return image.size.height + 16.0; //16 is for padding
}

如果您对单元格进行子类化,则可以在-layoutsubviews中调整imageView框架(超级之后)：

- (void)setupImageView
{
    UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectZero];
    imageView.contentMode = UIViewContentModeScaleAspectFit;
    imageView.clipsToBounds = YES;
    self.contentImageView = imageView;

    [self.contentView addSubview:imageView];
}

- (void)layoutSubviews
{
    [super layoutSubviews];

    CGRect bounds = self.contentView.bounds;
    float margin = 8.0;
    CGRect textViewFrame = CGRectZero;
    textViewFrame = CGRectMake(margin,roundf(margin * 2.0),bounds.size.width - (margin * 2.0),roundf(bounds.size.height - (margin * 4.0)));

    self.contentImageView.frame = textViewFrame;
}
