Using the URL Scheme below, I'm able to open the 'Settings' App from the app I'm currently working on.
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
Is it also possible to tweak the URL Scheme so that I can directly open the 'Notification Center' feature inside the 'Settings' App?
Kindly advise. All help appreciated!
I tried this code to prevent crashes from iOS versions and it's working for me:
if ([[UIApplication sharedApplication] respondsToSelector:#selector(openURL:options:completionHandler:)]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString] options:#{} completionHandler:nil];
} else {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];
}
tested on iOS 8 up;
you can try this url scheme: "prefs:root=NOTIFICATIONS_ID"
But u must add URL types in ur project: Click on ur Project in Project Navigator-> click on TARGET -> tab Info -> and add URL Types by click (+) and add URL scheme : "prefs".
if you still not clear check this Answer here
All the best,

Does UIApplication:openURL work?
NSString *iTunesLink = #"http://www.youtube.com/watch?v=TFFkK2SmPg4";
BOOL did = [[UIApplication sharedApplication] openURL:[NSURL URLWithString:iTunesLink]];
This does nothing.
I assume you're wanting to test a Custom URL Scheme. You will want to use canOpenURL to see if the URL can be opened first. canOpenURL returns a BOOL value indicating whether or not the URL’s scheme can be handled by some app installed on the device. If canOpenURL returns YES then you would continue to open the URL with openURL.
YouTube links open the YouTube app by default on iOS devices. This behavior is not yet testable on the new Apple TV as YouTube's app is not accessible in the tvOS beta.
Here's an example of how to use canOpenURL to see if Facebook is installed on an iOS device using its Custom URL Scheme:
Obj-C:
// Check if FB app installed on device
if ([[UIApplication sharedApplication] canOpenURL:[NSURL URLWithString:#"fb://"]]) {
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:#"fb://profile/355356557838717"]];
}
else {
// FB not installed
// Do something else
}
Swift:
// Check if FB app installed on device
if UIApplication.sharedApplication().canOpenURL(NSURL(string:"fb://")!) {
UIApplication.sharedApplication().openURL(NSURL(string:"fb://profile/355356557838717")!)
}
else {
// FB not installed
// Do something else
}
I'd anticipate that applications such as Facebook, and others, will implement their Custom URL Schemes in the same manner as their iOS counterparts.
I'm trying to open iOS's mail application by clicking a button.
So I did this :
NSString *mailString = [NSString stringWithFormat:#"mailto://test#test.com"];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailString]];
But nothing in particular happens... what's the problem ?
Thanks for your advices
#"mailto:test#test.com"
instead of
#"mailto://test#test.com"
Better way of doing this would be to use MFMailComposeViewController
And it works only on the real device, not on the simulator (in my case)
I'm creating an application where users can share data by sending emails to each other.
In this mail there is a link to my app (I created an URL scheme for my app)
But, if the users doesn't have my application on his iPhone, then when he clicks on the link, nothing happens.
My question : How could I do to launch my app when the application is installed on the user's iPhone and launch the Appstore or a website if this application is not installed
Thank you
canOpenURL is what you're looking for.
Here is an example for launching twitter app:
NSURL* twitterURL = [NSURL URLWithString:[NSString stringWithFormat:#"twitter:#%#", twitterUser]];
if ([[UIApplication sharedApplication] canOpenURL:twitterURL]) {
[[UIApplication sharedApplication] openURL:twitterURL];
} else {
NSURL* url = [NSURL URLWithString:#"http://itunes.apple.com/us/app/twitter/id333903271?mt=8"];
[[UIApplication sharedApplication] openURL:url];
}

In my app I have a button. Pressing the button takes me to the Facebook app with the scheme: fb://. But I want to have a scheme to link to my facebook page. fb://page/MYPAGENAME doesn't work or am I doing it wrong? Help is much appreciated!
Edit
This is what the method looks like now:
- (IBAction)facebookButton:(id)sender
{
NSURL *url = [NSURL URLWithString:#"fb://MYPAGENAME"];
[[UIApplication sharedApplication] openURL:url];
}
I've added a username to my page now.
Hey guys,
On my Xcode project, I am trying to open a web browser at the click of one of my buttons, but here's what I'm really trying to do. First of all, I am opening a web browser using this example code:
NSURL *fanPageURL = [NSURL URLWithString:#"fb://profile/210227459693"];
if (![[UIApplication sharedApplication] openURL: fanPageURL]) {
NSURL *webURL = [NSURL URLWithString:#"http://www.facebook.com/pages/Blackout-Labs/210227459693"];
[[UIApplication sharedApplication] openURL: webURL];
}
[super viewDidLoad];
Now this code works properly, but the problem is that it's closing my application and opens the link in the Safari application, which is not what I want. I went the other way around by creating another view (after click the button), then inserted a UIWebView using Interface Builder, but it still didn't work. So I was hoping someone can help me out how to open this link within my app instead of closing my app and opening the link in the Safari app, thanks
Look at SVWebViewController. It's a ready made UIViewController subclass with a UIWebView in it and all you need to do to show it is
SVWebViewController *webViewController = [[SVWebViewController alloc] initWithAddress:#"http://google.com"];
[self.navigationController pushViewController:webViewController animated:YES];
There is also a modal version, see the Usage Section.
You'll need to create a UIViewController subclass that has UIWebView as a subview, and show that when the button in tapped.
