如何在 UISplitViewController 中获取 detailViewController 的视图大小

Question

iOS 8+ ,Objective-C

我正在研究 UISplitViewController，我正在 detailViewController 上实现 textFields。我有额外两个按钮的底部视图，底部视图的高度为 60px，宽度取决于设备旋转。

所以，我想知道当splitViewController的displayMode为UISplitViewControllerDisplayModeAllVisible时，如何获取detailViewController的视图大小。

如有任何帮助，我们将不胜感激。

编辑：
我正在尝试使用 viewController、

中的以下代码

#define TABBAR_HEIGHT 50.0f
#define NAVIGATION_HEIGHT 64.0f
#pragma mark- ScreenRotation
- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{
    [self calculateFrameForFooterView];
}
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
    return YES;
}
- (BOOL)shouldAutorotate{
    return YES;
}
-(UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
    return UIInterfaceOrientationPortrait;
}
- (UIInterfaceOrientationMask)supportedInterfaceOrientations{
    return UIInterfaceOrientationMaskAllButUpsideDown;
}

- (void)calculateFrameForFooterView{
    //Caculate frame for footerView
    [self addBarButton];
    if(self.view.frame.size.width != frameClose.size.width){

        frameClose = CGRectMake(0,footerView.frame.origin.y,self.view.frame.size.width,footerView.frame.size.height);
    }
    frameClose.origin.y = self.view.frame.size.height- footerView.frame.size.height;
    CGFloat y;
    UIDeviceOrientation orientation = [[UIDevice currentDevice] orientation];
    if (orientation == UIDeviceOrientationLandscapeLeft || orientation == UIDeviceOrientationLandscapeRight){
        NSLog(@"\n\n**(Landscap)self.view.frame.size(%@)",NSStringFromCGSize(self.view.frame.size));
        frameClose.origin.y = self.view.frame.size.height- (footerView.frame.size.height);
        y = self.view.frame.size.height-(KEYBOARD_HEIGHT+footerView.frame.size.height+TABBAR_HEIGHT+NAVIGATION_HEIGHT-20);
    }else if(orientation == UIDeviceOrientationPortrait){
        NSLog(@"\n\n**(Portrait)self.view.frame.size(%@)",NSStringFromCGSize(self.view.frame.size));
        frameClose.origin.y = self.view.frame.size.height- (footerView.frame.size.height+TABBAR_HEIGHT+NAVIGATION_HEIGHT);
        y = self.view.frame.size.height-(KEYBOARD_HEIGHT+TABBAR_HEIGHT+NAVIGATION_HEIGHT+footerView.frame.size.height);
    }
    frameOpen  = CGRectMake(0,y,footerView.frame.size.width,footerView.frame.size.height);
}

好的，我在 - (void)viewWillLayoutSubviews{} 中解决了我的问题。
当我第二次旋转设备时，这个方法称为 twice.in，我收到了准确的尺寸。
所以首先，我从 - (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation{} 中删除 - (void)calculateFrameForFooterView 而不是将 - (void)calculateFrameForFooterView 放入 - (void)viewWillLayoutSubviews{}.
所以，最终通过这样做解决了我的问题。然而，这个解决方案并不完美，但这对我有用。这样我就不会接受自己的答案并等待好的答案。
谢谢
