请问你是想自定义 tabbar 的高度还是想调整 content view 的高度？你可以使用下面的方法来打印出 UITabBarController 的 View 的子视图信息来查看视图层级的布局:

- (void)viewDidAppear:(BOOL)animated
{

[super viewDidAppear:animated];
[self printViewHierarchy:self.tabBarController.view];
}

- (void)printViewHierarchy:(UIView *)superView
{
static uint level = 0;
for(uint i = 0; i < level; i++){
printf("\t");
}

const char *className = NSStringFromClass([superView class]).UTF8String;
const char *frame = NSStringFromCGRect(superView.frame).UTF8String;
printf("%s:%s\n", className, frame);

++level;
for(UIView *view in superView.subviews){
[self printViewHierarchy:view];
}
--level;
}

结果如下:

UILayoutContainerView:{{0, 0}, {320, 480}}
UITransitionView:{{0, 0}, {320, 480}}
UIViewControllerWrapperView:{{0, 0}, {320, 480}}
UIView:{{0, 0}, {320, 480}}
UITabBar:{{0, 431}, {320, 49}}
_UITabBarBackgroundView:{{0, 0}, {320, 49}}
_UIBackdropView:{{0, 0}, {320, 49}}
_UIBackdropEffectView:{{0, 0}, {320, 49}}
UIView:{{0, 0}, {320, 49}}
UITabBarButton:{{2, 1}, {156, 48}}
UITabBarSwappableImageView:{{54, 2}, {48, 32}}
UITabBarButtonLabel:{{68, 35}, {21, 12}}
UITabBarButton:{{162, 1}, {156, 48}}
UITabBarSwappableImageView:{{54, 2}, {48, 32}}
UITabBarButtonLabel:{{60, 35}, {36, 12}}
UIImageView:{{0, -0.5}, {320, 0.5}}
