URL Scheme为基础的NavigationController,让ViewController实现松耦合,不依赖
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。
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
使用URL管理机制代替UINavigationController的push和pop机制。
[[UMNavigationController config] setValuesForKeysWithDictionary:
[[NSDictionary alloc] initWithObjectsAndKeys:
@"UMDemoViewController", @"um://demo",
@"UMDemoViewController", @"um://demob",
nil]
];
或
[UMNavigationController setViewControllerName:@"UMDemoViewController" forURL:@"um://demo"];
[UMNavigationController setViewControllerName:@"UMDemoViewController" forURL:@"um://demob"];
UMNavigationController * umNav = [[UMNavigationController alloc]
initWithRootViewControllerURL:[[NSURL URLWithString:@"um://demo"]
addParams:[NSDictionary dictionaryWithObjectsAndKeys:
@"Demo", @"title", nil]]];
[self.window addSubView:umNav.view];
// 取代 [self.navigationController pushViewController: animated:];
[self.navigator openURL:[NSURL URLWithString:@"um://demo?title=NextDemo¶m=value"]];
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;
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];
}
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
