URLManager

URL Scheme为基础的NavigationController,让ViewController实现松耦合,不依赖

2014,新年快乐,码不停提!

使用

URLManager提供两个NavigationController,一个WebViewController和一个基础ViewController,可单独使用也可结合使用。

UMViewController

URLManager的基础ViewController,使用URLManager需要以UMViewController代替UIViewController作为基类。

UMViewController可以使用URL初始化(方法如下)。但一般不直接使用,而是通过NavigationController的工厂方法。

- (id)initWithURL:(NSURL *)aUrl; - (id)initWithURL:(NSURL *)aUrl query:(NSDictionary *)query; 

通过URL打开新的ViewController过程中会触发以下方法

- (BOOL)shouldOpenViewControllerWithURL:(NSURL *)aUrl; // 是否继续打开 - (void)openedFromViewControllerWithURL:(NSURL *)aUrl; // 从哪里来 

UMNavigator

UMNavigator是一个单例对象,可以监控当前显示的ViewController,并使用URL管理机制代替UINavigationController的push和pop机制。

注册URL和ViewController的对应关系

 [[UMNavigator sharedNavigator] setViewControllersForKeysFromDictionary:@{@"nava":navA, @"navb":navB}]; 

 [[UMNavigator sharedNavigator] setViewControllerName:@"UMDemoViewController" forURL:@"demo"]; 

 UINavigationController *navC = [[UINavigationController alloc] initWithRootViewControllerURL: [[NSURL URLWithString:@"um://demo"] addParams:[NSDictionary dictionaryWithObjectsAndKeys: @"Demo1", @"title", nil]]]; [[UMNavigator sharedNavigator] setViewController:navC forURL:@"navc"]; 

初始化UMNavigationController

UMNavigationController * umNav = [[UMNavigationController alloc] initWithRootViewControllerURL:[[NSURL URLWithString:@"um://demo"] addParams:[NSDictionary dictionaryWithObjectsAndKeys: @"Demo", @"title", nil]]]; [self.window addSubView:umNav.view]; 

打开新的ViewController

// 取代 [self.navigationController pushViewController: animated:]; [[UMNavigator sharedNavigator] openURL:[NSURL URLWithString:@"um://demo?title=NextDemo&param=value"]]; 

调用openURL: 将会触发以下方法

在调用方Controller中会触发以下方法,返回YES则执行push效果

- (BOOL)shouldOpenViewControllerWithURL:(NSURL *)aUrl; 

在被调用的ViewController中,触发以下方法

- (void)openedFromViewControllerWithURL:(NSURL *)aUrl; 

UMSlideNavigationController

侧栏导航,与Path侧栏滑动类似的效果。

 UINavigationController * navA = [[UINavigationController alloc] initWithRootViewController:[[UIViewController alloc] init]]; UMNavigationController * navB = [[UMNavigationController alloc] initWithRootViewControllerURL:[NSURL urlWithString:@"um://demo"]]; self.navigator = [[UMDemoSlideNavViewController alloc] initWithItems:@[@[navA, navB], @[navA]]]; 

侧栏滑动即将出现和已经消失时,将会发送两个通知。

- (void)viewWillAppear:(BOOL)animated{[super viewWillAppear:animated]; [[NSNotificationCenter defaultCenter] postNotificationName:UMNotificationWillShow object:nil]} - (void)viewDidDisappear:(BOOL)animated{[super viewDidDisappear:animated]; [[NSNotificationCenter defaultCenter] postNotificationName:UMNotificationHidden object:nil]} 

侧栏演示

UMWebViewController

当使用URL管理ViewController过程中,如果出现http协议的URL则自动调用UMWebViewController,载入WebView
