iOS开发——界面跳转方法总结

一、UITableBarController（标签栏控制器）中的界面跳转

我是在AppDelegate.m中写的代码，代码如下

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

//创建标签栏控制器tabBarController
UITabBarController *tabBarController = [[UITabBarController alloc] init];

//初始化firstView和secondView
FirstViewController *firstView = [[FirstViewController alloc] init];
SecondViewController *secondView = [[SecondViewController alloc]init];

//添加子视图控制器firstView和secondView
[tabBarController addChildViewController:firstView];
[tabBarController addChildViewController:secondView];

//设置底部标签栏上的title
firstView.tabBarItem.title = @"first";
secondView.tabBarItem.title = @"second";

self.window.rootViewController = tabBarController;
[self.window makeKeyAndVisible];
return YES;
}

效果如下：



二、UINavigationController（导航控制器）中的界面跳转

AppDelegate.m中

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

FirstViewController *firstView = [[FirstViewController alloc] init];

//创建导航控制器
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:firstView];
self.window.rootViewController = nav;

[self.window makeKeyAndVisible];
return YES;
}

FirstViewController.m中

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

//创建一个Lable标记这是fistView
UILabel *lable = [[UILabel alloc] initWithFrame:CGRectMake(50, 50, 100, 100)];
lable.text = @"fist";
[self.view addSubview:lable];

//创建一个button实现界面间的跳转
UIButton *button = [UIButton buttonWithType:UIButtonTypeRoundedRect];

button.frame = CGRectMake(50, 150, 150, 100);

[button setTitle:@"To secondView" forState:UIControlStateNormal];

[button addTarget:self action:@selector(buttonPressed) forControlEvents:UIControlEventTouchUpInside];

[self.view addSubview:button];
}

-(void)buttonPressed
{
SecondViewController *secondView = [[SecondViewController alloc] init];

//跳转到secondView的实现方法
[self.navigationController pushViewController:secondView animated:YES];
}

UINavigationController中跳转有三个方法，上述例子只实现了一个方法，还有其他两个方法。这里总结一下：

1.[self.navigationController pushViewController:firstView animated:YES];跳转到firstView界面
2.[self.navigationController popViewControllerAnimated:YES]; //返回上一页面
3.[self .navigationController popToRootViewControllerAnimated: YES ];  //返回根控制器

三、模态视图

很简单，就两个方法

[ self presentViewController:SVC animated: YES completion:nil];

[ self dismissViewControllerAnimated: YES completion: nil ];
