UINavigationController与UITabBarController相关问题

UINavigationController与UITabBarController相关问题

UINavigationController与UITabBarController混用是非常常见的,有时候会遇到UINavigationController推出(push)出controller后隐藏UITabBarController的问题,很容易对吧.

源码如下:

//

//  AppDelegate.m

//  NavigationController

//

//  Copyright (c) 2014年 Y.X. All rights reserved.

//

#import "AppDelegate.h"

#import "RootViewController.h"

#define CreateNavigationControllerWith(controller) \

[[UINavigationController alloc] initWithRootViewController:controller]

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];

    // 初始化导航栏控制器

    UINavigationController *newProductNC  = \

        CreateNavigationControllerWith([RootViewController new]);

    // 初始化TabBarController

    UITabBarController *rootBC = [[UITabBarController alloc] init];

    rootBC.viewControllers = @[newProductNC];

    // 交给系统管理

    self.window.rootViewController = rootBC;

    self.window.backgroundColor = [UIColor whiteColor];

    [self.window makeKeyAndVisible];

    return YES;

}

@end

//

//  RootViewController.m

//  NavigationController

//

//  Copyright (c) 2014年 Y.X. All rights reserved.

//

#import "RootViewController.h"

#import "SecondViewController.h"

@interface RootViewController ()

@end

@implementation RootViewController

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

{

    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];

    if (self)

    {

        self.title = @"YouXianMing";

    }

    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

{

    [self.navigationController pushViewController:[SecondViewController new]

                                         animated:YES];

}

@end

//

//  SecondViewController.m

//  NavigationController

//

//  Copyright (c) 2014年 Y.X. All rights reserved.

//

#import "SecondViewController.h"

@interface SecondViewController ()

@end

@implementation SecondViewController

- (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];

}

@end

效果:

将RootViewController.m中tapEvent:修改一下,如下所示:

效果(注意看底部的隐藏效果哦):

注意:隐藏与取消隐藏是成对出现的.
