Question

我用两个plist文件中的静态文本填充两个NSArrays。这些是使用RootViewController的第一个UITableView的标题和副标题。在横向中，表格与顶部对齐，没有空行或空白区域。表格显示正常。

在纵向模式下，表格显示但是在单个表格行的厚度或高度附近有空白区域。我已经调试了，两个数组都有5个数。有空格（似乎是一行高）和显示屏中的5个单元格。如果我通过选择一个项目进行导航并返回，则空间消失了。

这是我的RootViewController。

Answer 1

我解决了这个问题。这是半透明的YES属性。我先将它改为NO，然后在顶部正确对齐。然后我评论了我认为的默认属性。


    //self.navigationController.navigationBar.barStyle = UIStatusBarStyleBlackOpaque;
    //self.navigationController.navigationBar.tintColor = [UIColor blackColor];
    //self.navigationController.navigationBar.translucent = NO;

在纵向模式下，我的iPad的RootViewController表有一个空白的第一行，如果是行的话
