Question

我在基于航空主计长的应用程序中,有一些要素a、b、另一种观点的次观。当我推动控制员从WillAppear的角度看待这一问题时,我根据X的大小调整了a、b和c的大小和位置,以便妥善处理装置的定位。问题是,X的体积正在发生变化 >,之后称为WillAppear。我把X分门别类,并撰写了一套框架方法,以便确定一个断点,并试图找到原因。下面是图像的链接(由于缺少点子,我无法直接展示图像),显示WillAppear的断裂,以及把WillAppear与电话挂钩之后的裂痕。我需要帮助确定,为什么改变X的面积。感谢。

提前感谢。 (我希望这些图像将正确显示)。

Answer 1

我感谢所有答复,我提供的资料有限。最后,我发现问题的根源。我的nib文件包括一个工具栏(如果你使用导航控制器,那是一件坏事)。我也在呼吁我发言。

setToolbarHidden: NO

载于我的导航主计长。 I m new to program, and consider that the toolbar in the nib file will somehow be reflected as the Navigation view toolbar. 看来情况并非如此。我对问题发生的原因的理解是:

The view got loaded with a toolbar from the nib, and the navigation controller had a visible toolbar, so my X view height was 328. (the height of 2 toolbars were being subtracted when adjusting to the screen size. the one from the navigator controller and the one in the view).
After viewWillAppear, the navigation controller code apparently found the 2 toolbars, so it decided to hide the one in the navigation controller, increasing my X view height by 44 (to 372).

我将工具路障从刀子档案中删除,并将工具禁运物品添加到导航控制器工具路障上,打电话。

setToolbarItems

在观察WillAppear之后,框架的高度保持不变。

感谢这些答复。我希望,这些意见将使面临同样问题的其他人受益。
