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.
