Routable-iOS

我们在iOS中通常都是用 pushViewController 或者 presentViewController 的方式来做视图间的跳转，但是这种方式免不了要在一个controller中初始化另外一个controller，使用Routable可以实现controller之间的解耦。

这是routable-ios的github地址：https://github.com/clayallsopp/routable-ios

在Xcode中新建一个项目 RoutableStudy

1.用cocospods来引入这个库吧，在Pod文件中加入

platform :ios, '7.0'

pod 'Routable','~> 0.1.1'

然后 pod install

2.把 main interface置空,不使用storyboard

 

3.分别新建两个UIViewController:   删除默认的ViewController, 新建 FirstViewController 和 SecondViewController

4.在AppDelegate.m 中加入

#import <Routable/Routable.h>#import "FirstViewController.h"#import "SecondViewController.h"

在 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {  }  中加入

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];    // Override point for customization after application launch.    self.window.backgroundColor = [UIColor whiteColor];        UINavigationController *nav = [[UINavigationController alloc] initWithNibName:nil bundle:nil];    [[Routable sharedRouter] map:@"firstViewController" toController:[FirstViewController class]];    [[Routable sharedRouter] map:@"secondViewController" toController:[SecondViewController class] withOptions:[[UPRouterOptions modal] withPresentationStyle:UIModalPresentationFormSheet]];    [[Routable sharedRouter] setNavigationController:nav];        [self.window setRootViewController:nav];    [self.window makeKeyAndVisible];        [[Routable sharedRouter] open:@"firstViewController"];

5. FirstViewController

- (id)initWithRouterParams:(NSDictionary *)params {    if ((self = [self initWithNibName:nil bundle:nil])) {        self.title = @"FirstViewController";    }    return self;}- (void)viewDidLoad {    [super viewDidLoad];        UIButton *modal = [UIButton buttonWithType:UIButtonTypeRoundedRect];    [modal setTitle:@"SecondViewController" forState:UIControlStateNormal];    [modal addTarget:self action:@selector(tapped:) forControlEvents:UIControlEventTouchUpInside];    [modal sizeToFit];    [modal setFrame:CGRectMake(0, self.view.bounds.size.height - modal.frame.size.height, modal.frame.size.width, modal.frame.size.height)];        [self.view addSubview:modal];}- (void)tapped:(id)sender {    [[Routable sharedRouter] open:@"secondViewController"];}

6. SecondViewController

- (id)initWithRouterParams:(NSDictionary *)params {    if ((self = [self initWithNibName:nil bundle:nil])) {        self.title = @"SecondViewController";    }    return self;}- (void)viewDidLoad {    [super viewDidLoad];        UIButton *modal = [UIButton buttonWithType:UIButtonTypeRoundedRect];    [modal setTitle:@"Close" forState:UIControlStateNormal];    [modal addTarget:self action:@selector(tapped:) forControlEvents:UIControlEventTouchUpInside];    [modal sizeToFit];    [modal setFrame:CGRectMake(0, self.view.bounds.size.height - modal.frame.size.height, modal.frame.size.width, modal.frame.size.height)];    [self.view addSubview:modal];        UIButton *user = [UIButton buttonWithType:UIButtonTypeRoundedRect];    [user setTitle:@"FirstViewController" forState:UIControlStateNormal];    [user addTarget:self action:@selector(tappedUser:) forControlEvents:UIControlEventTouchUpInside];    [user sizeToFit];    [user setFrame:CGRectMake(self.view.bounds.size.width - user.frame.size.width , self.view.bounds.size.height - user.frame.size.height, user.frame.size.width, user.frame.size.height)];        [self.view addSubview:user];}- (void)tapped:(id)sender {    [[Routable sharedRouter] pop];}- (void)tappedUser:(id)sender {    [[Routable sharedRouter] open:@"firstViewController"];}

跑一下程序吧，controller之间的跳转不再需要引入其它的controller并且alloc了。

Routable 不只是只有解偶的作用  先到这里吧 有更多领悟再来补充。
