DeepLink Kit is a splendid route-matching, block-based way to handle your deep links. Rather than decide how to format your URLs, parse them, pass data, and navigate to specific content or perform actions, this library and a few lines of code will get you on your way.
Try the DeepLinkKit sample project by running the following command:
pod try "DeepLinkKit"DeepLinkKit is available through CocoaPods. To install the library, simply add the following line to your Podfile:
pod "DeepLinkKit"If you don't use CocoaPods, you can include all of the source files from the DeepLinkKit directory in your project.
Add deep link support to your app in 5 minutes or less following these simple steps.
Note: As of 1.0.0, all imports should be updated to import <DeepLinkKit/DeepLinkKit.h>.
1. Make sure you have a URL scheme registered for your app in your Info.plist
**2. Import DeepLinkKit**
#import <DeepLinkKit/DeepLinkKit.h>**3. Create an instance of `DPLDeepLinkRouter` in your app delegate**
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.router = [[DPLDeepLinkRouter alloc] init];
return YES;
}**4. Register a route handler**
self.router[@"/log/:message"] = ^(DPLDeepLink *link) {
NSLog(@"%@", link.routeParameters[@"message"]);
};**5. Pass incoming URLs to the router**
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
return [self.router handleURL:url withCompletion:NULL];
}6. Passing NSUserActivity objects to the router (optional)
Note: If your application supports Apple's new universal links, implement the following in your app delegate:
- (BOOL)application:(UIApplication *)application
continueUserActivity:(NSUserActivity *)userActivity
restorationHandler:(void (^)(NSArray *))restorationHandler {
return [self.router handleUserActivity:userActivity withCompletion:NULL];
}Learn more about the DeepLinkKit by reading our Integration Guide.
URLs coming into your app will be in a similar format to the following:
<scheme>://<host>/<path-component>/<path-component>
When registering routes, it's important to note that the first forward slash in your registered route determines the start of the path to be matched. A route component before the first forward slash will be considered to be the host.
Say you have an incoming URL of twitter://timeline
// Matches the URL.
router[@"timeline"] = ^{ … }
// Does not match the URL.
router[@"/timeline"] = ^{ … }In another example, a URL of twitter://dpl.com/timeline
// Matches the URL.
router[@"/timeline"] = ^{ … }
// Does not match the URL.
router[@"timeline"] = ^{ … }
You can also be scheme specific. If you support multiple URL schemes in your app, you can register routes specific to those schemes as follows:
An incoming URL of scheme-one://timeline
// Matches the URL.
router[@"scheme-one://timeline"] = ^{ … }
// Does not match the URL.
router[@"scheme-two://timeline"] = ^{ … }Does your app support AppLinks? You can easily handle incoming AppLinks by importing the AppLinks category DPLDeepLink+AppLinks. The AppLinks category provides convenience accessors to all AppLinks 1.0 properties.
router[@"/timeline"] = ^(DPLDeepLink *link) {
NSURL *referrerURL = link.referralURL;
NSString *someValue = link.extras[@"some-key"];
}To run the example project, run pod try DeepLinkKit in your terminal. You can also clone the repo, and run pod install from the project root. If you don't have CocoaPods, begin by follow this guide.
There are two demo apps, SenderDemo, and ReceiverDemo. ReceiverDemo has some registered routes that will handle specific deep links. SenderDemo has a couple actions that will deep link out to ReceiverDemo for fulfillment.
Run theSenderDemo build scheme first, then stop the simulator and switch the build scheme to ReceiverDemo and run again. Now you can switch back to the SenderDemo app in the simulator and tap on one of the actions.
You can also create deep links with DPLMutableDeepLink. Between two DeepLinkKit integrated apps, you can pass complex objects via deep link from one app to another app and easily get that object back on the other end.
In the first app:
DPLMutableDeepLink *link = [[DPLMutableDeepLink alloc] initWithString:@"app-two://categories"];
link[@"brew-types"] = @[@"Ale", @"Lager", @"Stout", @"Wheat"]
link[@"beers"] = @{
@"ales": @[
@{
@"name": @"Southern Tier Pumking Ale",
@"price": @799
},
@{
@"name": @"Sierra Nevada Celebration Ale",
@"price": @799
}
],
@"lagers": @[
...
],
...
}
[[UIApplication sharedApplication] openURL:link.URL];
In the second app:
router[@"categories"] = ^(DPLDeepLink *link) {
NSArray *brewTypes = link[@"brew-types"];
NSDictionary *beers = link[@"beers"];
