我已经在xcode 4中完成了我的应用程序编码，但我正在尝试在xcode 5上的这个代码在UITableview中出现很多问题。表格行和表格内容不可见。通常表格显示正确，但我在tableview中为子视图设置水平和分隔线，时间范围只设置行和内容不可见。
在图片中，我将桌面视图的背景颜色设置为蓝色，因此此内容区域仅以白色显示

答案 0 :(得分：0)
我认为您在表格单元格中添加了一些内容，例如removeFromSuperView，以便只有该视图不可见，请删除以下代码（如果代码中有代码）
[myCell.subviews makeObjectsPerformSelector：@ selector（removeFromSuperview）]; [myCell.contentView.subviews makeObjectsPerformSelector：@selector（removeFromSuperview）];
