如何设置3个UITable和2个导航栏的位置？
我的 XIB 有 3 个 UITable 和 3 个导航栏。UITable 是动态缩放的，我使用导航栏来分隔 UITable 并显示 UITable 名称的标题。
我想在第一个表格下设置第一个导航栏，在第二个表格下设置第二个导航栏。
我尝试找到第一个桌子的框架来获取位置 x，y 和桌子的高度，但它不起作用。
- (void)viewDidLoad
{
blah blah...
CGRect table1frame = table1.frame; //But it don't work
}
我不知道从哪里得到每个桌子框架。 请帮助我或指导我。非常感谢

- (void)viewDidLoad

我不确定我是否理解您要执行的操作，但请记住，当调用
viewDidLoad时，视图控制器视图的几何形状（其边界）尚未设置。任何子视图的边界（和框架）也尚未设置。这意味着此时所有帧几乎都设置为零。而且，如果您尝试访问视图的框架或其任何子视图的框架，这可能就是您所注意到的，因此，如果您需要基于视图的几何形状（在其框架或任何子视图的框架上）执行任何操作 ，其子视图），通常在
viewWillAppear中完成。您的问题可能不是在哪里获取表格视图的框架，而是何时获取它。您正在正确的位置（表视图的框架属性）寻找它，但您还为时过早。我希望这有帮助。
I'm not sure I understand what you're trying to do, but keep in mind that the geometry of the view controller's view (its bounds) is not yet set when
viewDidLoadis called. The bounds (and frames) of any subviews have not been set either. That means that all frames are pretty much set to zero at this point. And, that may be what you are noticing if you are trying to access the view's frame, or the frame of any of its subviews,So, if you need to do anything based on the view's geometry (on its frame or the frame of any of its subviews), it is generally done in
viewWillAppear.Your problem may not be where to get the table view's frame, but when to get it. You are looking for it in the right place (the table view's frame property), but you are too early. I hope this is helpful.
