Routable

Routable is an in-app native URL router, for iOS. Also available for Android.

Usage

Set up your app's router and URLs (usually done in application:didFinishLaunchingWithOptions:):

[[Routable sharedRouter] map:@"users/:id" toController:[UserController class]];
// Requires an instance of UINavigationController to open UIViewControllers
[[Routable sharedRouter] setNavigationController:aNavigationController];

Implement initWithRouterParams: in your UIViewController subclass:

@implementation UserController

// params will be non-nil
- (id)initWithRouterParams:(NSDictionary *)params {
  if ((self = [self initWithNibName:nil bundle:nil])) {
    self.userId = [params objectForKey:@"id"];
  }
  return self;
}

Then, anywhere else in your app, open a URL:

NSString *aUrl = @"users/4";
[[Routable sharedRouter] open:aUrl];

If you wish to do custom allocation of a controller, you can use +allocWithRouterParams:

[[Routable sharedRouter] map:@"users/:id" toController:[StoryboardController class]];

@implementation StoryboardController

+ (id)allocWithRouterParams:(NSDictionary *)params {
    UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Storyboard" bundle:nil];
    StoryboardController *instance = [storyboard instantiateViewControllerWithIdentifier:@"sbController"];
    instance.userId = [params objectForKey:@"id"];

    return instance;
}

Set ignoresExceptions to YES to NOT throw exceptions (suggested for a Release/Distribution version)

[[Routable sharedRouter] setIgnoresExceptions:YES];

Installation

CocoaPods

pod 'Routable', '~> 0.1.1'

#import <Routable/Routable.h>

If you're not able to use CocoaPods, please install Routable as a git submodule and add the files to your Xcode project.

Features

Anonymous Callbacks

You can invoke anonymous callbacks with Routable:

[[Routable sharedRouter] map:@"invalidate/:id" toCallback:^(NSDictionary *params) {
  [Cache invalidate: [params objectForKey:@"id"]]];
}];

[[Routable sharedRouter] open:@"invalidate/5h1b2bs"];

Presentation Options

You can configure if and how a UIViewController is presented modally with UPRouterOptions:

UPRouterOptions *options = [[UPRouterOptions modal] withPresentationStyle: UIModalPresentationFormSheet];
[self.router map:@"info" toController:[InfoController class]
                          withOptions:options];

UPRouterOptions has the following DSL setters:

modal
withPresentationStyle:
withTransitionStyle:
forDefaultParams:

Open External URLs

Sometimes you want to open a URL outside of your app, like a YouTube URL or open a web URL in the browser. You can use Routable to do that:

[[Routable sharedRouter] openExternal:@"http://www.youtube.com/watch?v=oHg5SJYRHA0"];

Multiple Routers

If you need to use multiple routers, simply create new instances of Router:

UPRouter *adminRouter = [Routable newRouter];
[adminRouter map:@"profile" toController: [AdminProfile class]];

UPRouter *userRouter = [Routable newRouter];
[userRouter map:@"profile" toController: [UserProfile class]];
