I am trying to share a link via Whatsapp and have read many tutorials as well. I am able to share my link successfully but the problem is that user doesn't come back to my app after sharing on whatsapp.
Here is the code I am using to share:
NSString *referralLink = [NSString stringWithFormat:#"some link here"];
NSString *textToSend = [[NSString stringWithFormat:#"whatsapp://send?text=%#",referralLink] stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding];
NSURL *whatsappURL = [NSURL URLWithString:textToSend];
if ([[UIApplication sharedApplication] canOpenURL: whatsappURL]) {
[[UIApplication sharedApplication] openURL: whatsappURL];
}
I know that I have to use URL Scheme to achive this and I have used it too. But I am not sure that I am using it in correct way.
Here is the screenshot of my .info file.
Behind the black bar, I have entered the bundle identifier. i.e com.abc.myapp
This is default behavior in iOS, only if the app developer of the app you are calling allows an option to send the user back to calling app will it work.
WhatsApp does not have such a feature and this is therefore not possible.
Also you should not use the whatsapp: url scheme in your apps info.plist. Doing this will make any app calling whatsapp: to open your app.
you should give your own url scheme(a unique identifier), probably your AppName. You are not supposed to use whatsapp
Now IOS 9 Do support the Apps to come back to the app when they are invoking any third party app being called using OpenURL scheme.
You can make a OS version based support at this moment unless you come to minimal support of IOS 9 for your application.

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.
I want to open my ios app using URL schemes. I am able to open app using this.
But I want if app is not installed then app store should be opened where user can download app.
Is this possible? How can I do that?
EDIT
Explaining question step wise:
I have a mail in my inbox with a url.
I click on URL then
i. If app is installed in phone, app will launch.
ii. Otherwise app store will be opened to download app.
Thank
I handled it via my server side code:
if ((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i))) {
location.replace("com.myapp://");
setTimeout(function() {
if (!document.webkitHidden) {
location.replace("https://itunes.apple.com/app/xxxxxxxx");
}
}, 25);}
else if ((navigator.userAgent.match(/android/i)) || (navigator.userAgent.match(/Android/i))) {
location.replace("https://play.google.com/store/apps/details?id=packagename&hl=en");}
else {
location.replace("http://www.example.com");}
I put this in my www.mysite.com/download page & share this url via campaigns.
What you're describing is called Deferred Deep Linking (Deep Linking refers to using a link to open your app, even directly to a specific piece of content, and Deferred means that it works even if the app isn't installed first).
Unfortunately there's no native way to accomplish this yet on either iOS or Android. URL schemes don't work, because they always fail if the app isn't installed. Apple's new Universal Links in iOS 9 get closer, but you'd still have to handle redirecting the user from your website to the App Store
A free service like Branch.io (full disclosure: they're so awesome I work with them) can handle all of this for you though. Here's the docs page covering exactly how to create email links like you described: https://dev.branch.io/features/email-campaigns/overview/
If your App is not installed in device then, you can open app store using below lines of code:
NSString *iTunesUrlofApp = #"itms://itunes.apple.com/us/app/apple-store/...";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesUrlofApp]];
Try below code:
if([[UIApplication sharedApplication] canOpenURL:url]){
// Means your app is installed, and it can be open
[[UIApplication sharedApplication] openURL:url];
}
else{
//Your app is not installed so, Open app store with your apps iTunes Url
NSString *iTunesUrlofApp = #"itms://itunes.apple.com/us/app/apple-store/...";
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesUrlofApp]];
}
After iOS 5 you can also use https:// to avoid redirections.
Edit:
Check the link to open app from url if installed: Universal links to open app from Url.
Is it possible to use a web based API push service like "Boxcar" linked to a button in my webpage, to send a silent push to my iphone in which the iphone will interrupt the currently running app, and reopen (previously opened/in background) the linked app with the push's updated info?
So in all: open an app, go to another app (such as twitter), then on my webpage press a button and have twitter interrupted and brought back to the original app with updated data from the push.
Another question would be, do I need a 3rd party API to accomplish this? or can i use purely apple code?
I am a fairly new programmer and very new to APN's and app building, so any help would be greatly appreciated. Thanks!
First off, welcome to SO!
Unfortunately, there is no way to open up applications from the background programmatically in iOS. Apple leaves that to the user. You would have to send a push to the phone that the user interacts with in order to open up the app to a specific page. The only way you can open up another app is using URL Schemes (see here: https://developer.apple.com/library/ios/documentation/iPhone/Conceptual/iPhoneOSProgrammingGuide/Inter-AppCommunication/Inter-AppCommunication.html)
The problem with that is you can only do it from YOUR app to someone else's app (or if you have a widely enough used app, some people might even link to yours, although I'm not sure Twitter would ever do that).
Basically what URL Schemes do is allow the phone to open up a URL as if it were a website. Before it loads the webpage, it checks to see if any apps respond to that URL. For instance, if you wanted to open Maps to a specific location:
NSString *title = #"title";
float latitude = 35.4634;
float longitude = 9.43425;
int zoom = 13;
NSString *stringURL = [NSString stringWithFormat:#"http://maps.google.com/maps?q=%##%1.6f,%1.6f&z=%d", title, latitude, longitude, zoom];
NSURL *url = [NSURL URLWithString:stringURL];
[[UIApplication sharedApplication] openURL:url];
Hope that answers your question!
I have to add my website link in iPad settings for our app. I know how to add simple text but don't know how to add links so that clicking on it safari will open.
Same as done in facebook / twitter app for "learn more about facebook/twitter"
I have checked this url but didn't find how to add URLs.
Write the following code to your action method of setting row/button
NSURL *yourLinkURL = [[NSURL URLWithString: #"https://www.google.co.in" ];
[[UIApplication sharedApplication] openURL: yourLinkURL];
You can't do that with the settings bundle. The only reason Facebook and Twitter have it is because they are more integrated with the system, so they run a special settings bundle that normal developers don't have access to.
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.
