表視圖不可見

Question

我已經完成了我在xcode 4中的應用程序編碼，但我嘗試在xcode 5上的此代碼在UITableview中發生了很多問題。表格行和表格的內容不可見。通常表格顯示正確，但我設置水平和分隔線在tableview中的子視圖的時間框架只設置行和內容不可見。

在畫面我是在藍色的tableview設置背景顏色，所以這裏的內容區域僅出現在白色

     UIView *subView=[[UIView alloc]initWithFrame:CGRectMake(5, 0, 510, ([subViewsDataArr count] * 50) + 10)]; 
     subView.backgroundColor=[UIColor clearColor];

     subView.layer.borderColor = [[UIColor blackColor] CGColor]; 
     subView.layer.cornerRadius=5; 
     [myCell addSubview:subView]; 

     int y = 5; 
     for (int j=0; j<[subViewsDataArr count]; j++, y = y+50) { 
      UIView *cellView =[[UIView alloc] init]; 
      cellView.frame =CGRectMake(5, y, 500, 50); 
      cellView.backgroundColor =[UIColor clearColor];

我覺得你像removeFromSuperView表格單元格中添加一些東西，以便只有視圖不可見請刪除以下代碼，如果代碼中有代碼

[myCell.subviews makeObjectsPerformSelector：@selector（removeFromSuperview）]; [myCell.contentView.subviews makeObjectsPerformSelector：@selector（removeFromSuperview）];
