iOS之UINavigationController与UITabBarController的使用

1、AppDelegate.m

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

UINavigationController* newProductNC = CreateNavigationControllerWith([RootViewController new]);
UITabBarController* rootBC = [[UITabBarController alloc] init];
rootBC.viewControllers = @[newProductNC];
self.window.rootViewController = rootBC;
self.window.backgroundColor = [UIColor whiteColor];
[self.window makeKeyAndVisible];
return YES;
}2、RootViewController
#import "RootViewController.h"
#include "SecondViewController.h"

@interface RootViewController ()

@end

@implementation RootViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
{
self.title = @"NavigationController1";
}
return self;
}

- (void)viewDidLoad
{
[super viewDidLoad];

// 设定背景色
self.view.backgroundColor = [UIColor whiteColor];

// 点击手势
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self
action:@selector(tapEvent:)];

// 添加手势
[self.view addGestureRecognizer:tapGesture];
}

- (void)tapEvent:(UIGestureRecognizer *)sender
{
//push的时候隐藏TabBar和NavigationBar
self.hidesBottomBarWhenPushed = YES;
self.navigationController.navigationBarHidden = YES;
//执行push
[self.navigationController pushViewController:[SecondViewController new]
animated:YES];
//返回时取消隐藏
self.hidesBottomBarWhenPushed = NO;
}3、SecondViewController
#import "SecondViewController.h"

@interface SecondViewController ()

@end

@implementation SecondViewController

BOOL isHide = true;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
{

}
return self;
}

- (void)viewDidLoad
{
[super viewDidLoad];
self.view.backgroundColor = [UIColor whiteColor];

//添加手势操作
UITapGestureRecognizer *tapGesture = [[UITapGestureRecognizer alloc] initWithTarget:self
action:@selector(tapEvent:)];
[self.view addGestureRecognizer:tapGesture];
}

//手势操作响应函数
-(void)tapEvent:(id)sender
{
//实现点击时隐藏与显示交替出现
if (isHide) {
self.navigationController.navigationBarHidden = NO;//隐藏NavigationBar
self.tabBarController.tabBar.Hidden = NO;//隐藏TabBar
}else{
self.navigationController.navigationBarHidden = YES;//显示NavigationBar
self.tabBarController.tabBar.Hidden = YES;//显示TabBar
}
isHide = !isHide;
}
