您可以通过创建一个包含UINavigationController的自定义UIViewController来实现此目的.创建一个名为“CustomViewController”的新类,并粘贴以下代码：

接口

#import <UIKit/UIKit.h>

@interface CustomViewController : UIViewController

- (id)initWithViewController:(UIViewController*)viewController bottomView:(UIView*)bottomView;

@end

执行：

#import "CustomViewController.h"

@implementation CustomViewController

- (id)initWithViewController:(UIViewController*)viewController bottomView:(UIView*)bottomView
{
    self = [super init];
    if (self) {

        //  Set up view size for navigationController; use full bounds minus 60pt at the bottom
        CGRect navigationControllerFrame = self.view.bounds;
        navigationControllerFrame.size.height -= 60;
        viewController.view.frame = navigationControllerFrame;

        //  Set up view size for bottomView
        CGRect bottomViewFrame = CGRectMake(0,self.view.bounds.size.height-60,self.view.bounds.size.width,60);
        bottomView.frame = bottomViewFrame;

        //  Enable autoresizing for both the navigationController and the bottomView
        viewController.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;
        bottomView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin;

        //  Add views as subviews to the current view
        [self.view addSubview:viewController.view];
        [self.view addSubview:bottomView];
    }
    return self;
}

@end

现在使用CustomViewController：

UIView *myBottomView = [[UIView alloc] initWithFrame:CGRectMake(0,200,100)];
myBottomView.backgroundColor = [UIColor redColor];

CustomViewController *customViewController = [[CustomViewController alloc] initWithViewController:<yourNavigationController> bottomView:myView];
