I have two applications and i want to open them from each other (like facebook opens messenger).
After a little search i found that i have to know the url scheme of my app, but i don't know how can i declare it. In my urlSchemes are only facebook's schemes.
var url = NSURL(string: "")
UIApplication.sharedApplication().canOpenURL(url!)
I found that code and as i understand i have to put in the url my urlScheme.
Any help?
Here is a good tutorial on setting up URL Schemes within you app: https://dev.twitter.com/cards/mobile/url-schemes
Incase this tutorial disappears, heres the info:
Configure our Xcode project
Go to Your Target > Info > URL Types
You need to define your custom URL type. Remember, you want to open the app via birdland://, so that will be your URL scheme. We also need to assign an unique identifier to the scheme. Apple recommends that you use reverse DNS notation to ensure that there are no name collisions on the platform, e.g com.mycompany.ios.
That’s it! You’ve configured the app with simple support for the URL scheme birdland://. There is, of course, much more that you can do with Custom URL Schemes. To find out more, check out Apple’s documentation.
Now, to check that our registered URL scheme works, we’ll head out to Safari. Press the “Home” button in the Simulator (or press command-shift-H) to reach the Home Screen. Open Safari.
Next, type birdland:// in the address bar of Safari. Just as you can with http:// URLs, you’re asking Safari to open the “birdland” scheme. Press Go.
NSString *openAppURL = #"yourappname://";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:openAppURL]];
//check if app is installed or not
BOOL canOpenURL = [[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:openAppURL]];

I installed Meeseva app on my device. When I try to open it programmatically it's not opening.
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:#"Meeseva App://location?id=1"]]) {
NSString *mystr=[[NSString alloc] initWithFormat:#"Meeseva App://location?id=1"];
NSURL *myurl=[[NSURL alloc] initWithString:mystr];
[[UIApplication sharedApplication] openURL:myurl];
}
When I opened fb, twitter, google+ and etc... all are opening successfully.
Can any solve this this issue?
App link is
https://itunes.apple.com/in/app/meeseva-app/id1121539928?mt=8
Is there any another way to open installed app programatically?
If your app can receive specially formatted URLs, you should register the corresponding URL schemes with the system. Apps often use custom URL schemes to vend services to other apps.
Hence "Meeseva" app might not have created a custom url for their app. So you can't do anything for it.
As mentioned above the apps which want to provide support for url schema then they have to create a custom URL schemes.
You need to find out what the correct URL scheme of the Meeseva App is. Meeseva App:// does not seem to be a valid URL scheme as it has a space in the middle.
For example the Google Maps URL scheme is comgooglemaps://, not Google Maps://
Usually developers make their URL scheme public in their documentation. However this is a feature that needs to be implemented and apps don't support this "out of the box". If the developer did not implement this, the app can't be opened via link.
Alternatively it is possible that the app reacts on "universal links". That means if there is a website for the app, iOS might ask you whether to open that website in the app or in Safari. In that case you could simply link to the website and let the user decide how the link should be opened. However, again, this needs to be implemented by the developer. If the app does not support universal links either, there's no way for you to open the app at all.
The official Apple documentation doesn't seem to specify whether iOS URL schemes are case-sensitive or not.
Can I register myApp and still get opened for someone calling openURL: on MyApp://params?
They are not case-sensitive.
You can verify this by entering both sms:// and sMs:// into the URL box in Safari.
Also, it seems that third-party URL schemes in the Safari address bar now lead to a page not found error. This must be new in iOS 9.3.x, because it did not do this before. Entering the URL into another app (e.g. Notes) and then opening it still works.
Edit: the above hypothesis about iOS 9.3.x is actually a bit more nuanced...
They work if…
You are starting from a blank screen
A page is still loading when you request the custom URL scheme
They do NOT work if…
You are on a webpage that has fully loaded before you request the custom URL scheme
Go figure
What I want to do is,
We have having one product info on Website.
That product is available on store.
what we have on website is that, Product info and one button for that product.
I want to take two actions on that button.
When User opens website on iPad or iPhone on Safari (browser) and click on GetProduct button, then following two actions must be taken place.
1. If user is already having product installed on device then directly open the app in device.
2. If user is not having the app on device then link user to the app on store, so he can download from there.
I already handled second condition,
but how to handle the first condition.
If I am already having the app then how to open it on action of button click in browser.
You can achieve what you're asking for by using a URL scheme. This will enable you to call the openUrl: method with your application's url scheme which will then launch your app.
Here's how you setup a custom url scheme:
Open your app's Info.plist and add a row with a key called URL Types.
Expand the URL Types item, and Item 0 under it and you'll see URL Identifier
Enter your app's bundle identifier (e.g. com.myCompany.myApp) as the URL Identifier value.
Add another row to Item 0 and enter URL Schemes.
Expand the URL Schemes and under Item 0 type in the name for your custom scheme (e.g. myScheme).
You should now be able to open your app from Safari by typing myScheme:// in the address bar.
Alternatively, from your app, you can launch the other app like this:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"myScheme://"]];
Note that you can also send parameters to the app you're launching with the url scheme (more on that here).
With iOS9 Apple introduced a way to open installed app from Links. Here is the official link for this : Apple universal links
Is it possible to retrieve the name of the app which will handle a specific URL?
In other apps I saw "Open Link in Safari" and if you click, YouTube or whatever else will launch. I don't really like this behavior and I'd like the get the corresponding app name before calling
[[UIApplication sharedApplication] openURL:[NSURL someURL]];
to set the right button title.
No, that's not possible with the official SDK.
If you really want that you could create a file/database with the most common URL schemes on iOS (check this), then ship your app with it.
I wanted to open Facebook and Twitter apps from my app. I find very simple way like:
NSURL *url = [NSURL URLWithString:#"fb://profile"];
[[UIApplication sharedApplication] openURL:url];
And there are many others url for open different page of Facebook. How can I check if Facebook app exist on iPhone? What happens if the application is not install on device? Now I try to use this method on iOS Simulator but nothing happened. It's bug of iOS Simulator? Only tomorrow I will have chance to check on device.
You can check if a URL would likely open ahead of time using the canOpenURL method of UIApplication.
http://developer.apple.com/library/ios/DOCUMENTATION/UIKit/Reference/UIApplication_Class/Reference/Reference.html#//apple_ref/occ/instm/UIApplication/canOpenURL:
Also! You can pass values for the facebook page you'd like. This Stack Overflow includes a link to a wiki with all the variations:
Launching Facebook and Twitter application from other iOS app
If you know the URL scheme that the other app is using (e.g. fb:// for the Facebook app), you can first ask whether your UIApplication object can open such URLs in the first place, with canOpenURL:. You can use this, for instance, to decide whether to display a link at all, or whether to direct the user to Safari (with a normal web URL) instead.
As third-party apps cannot be installed on the Simulator as far as I know, the only way to test compatibility with them is on an actual device.
