导航控制器使用了导航堆栈。根视图控制器(Settings)在堆栈最底层,以此类推。能够理解为一本书,一页一页的。这样就控制了 试图控制器php
self.title = @"Settings"; // 改变标题 //其实这是一个区域 self.navigationItem.titleView = 这是一个View 那就好办了,咱们能够添加button imageView UISegmentedControl选项卡
//视图控制器 ViewController1* vc = [[ViewController1 alloc] init]; //导航控制器 UINavigationController* nc = [[UINavigationController alloc] initWithRootViewController:vc]; self.window.rootViewController = nc;
ViewController2* vc2 = [[ViewController2 alloc] init]; //进入第二个页面 [self.navigationController pushViewController:vc2 animated:YES]; //返回上一个页面 [self.navigationController popViewControllerAnimated:YES]; //返回根页面 [self.navigationController popToRootViewControllerAnimated:YES]; //返回指定页面 [self.navigationController popToViewController:vcX animated:YES];
bar:spa
包含左右UIBarButtonItem,也就是左右两个按钮,下面添加左面按钮:code
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemReply target:self action:@selector(clickLeftButton)]; //初始化并非initWithBarButt....一种,聪明的你确定知道comand点进去了。有initWithTitle。。。等等,这个能够改变按钮文字 self.navigationItem.leftBarButtonItem = leftButton;
固然左边的默认显示的。右面的就不在这里添加了吧orm
下面是按钮样式,自行参考get
toolBar:string
//显示toolBar [self.navigationController setToolbarHidden:NO]; //添加toolBar 把UIBarButtonItem 放到,,,,,///UIBarButtonSystemItemFlexibleSpace 空白按钮风格 [self setToolbarItems:[NSArray arrayWithObjects:,,,, nil]; ///本身添加UIToolbar 初始化 用setItems 添加 UIBarButtonItem UIToolbar* toolBar = [[UIToolbar alloc] initWithFrame:CGRectMake(0, 416-84, 320, 44)]; toolBar.hidden = YES; //toolBar.backgroundColor = [UIColor redColor]; [self.view addSubview:toolBar]; //批量给Toolbar添加按钮 NSMutableArray* array = [NSMutableArray array]; for (int i = 0; i < 7; i++) { if (i%2==0) { UIBarButtonItem* button = [[[UIBarButtonItem alloc] initWithTitle:[NSString stringWithFormat:@"%d",i] style:UIBarButtonItemStyleBordered target:self action:nil] autorelease]; [array addObject:button]; } else { UIBarButtonItem* button = [[[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemFlexibleSpace target:self action:nil] autorelease]; //宽 //FixedSpace 固定空白 //FlexibleSpace 灵活分布空白 //button.width = 50; [array addObject:button]; } } //若是是咱们本身写的toolBar,用这个方法添加 [toolBar setItems:array animated:YES]; //若是是导航自带的toolBar,用这个方法添加 [self setToolbarItems:array];
自定义按钮it
//把自定义的按钮mybutton 添加到 UIBarButtonItem barButton = [[UIBarButtonItem alloc] initWithCustomView:mybutton];
// 让iOS7 导航控制器不透明io
self.navigationController.navigationBar.translucent = NO; self.edgesForExtendedLayout = UIRectEdgeNone;
//隐藏导航栏table
[[self navigationController] setNavigationBarHidden:YES animated:YES];
