iOS 9 has made a small change to the handling of URL scheme  You must whitelist the url s that your app will call out to using the LSApplicationQueriesSchemes key in your Info plist  Please see post here  http   awkwardhare com post 121196006730 quick-take-on-ios-9-url-scheme-changes The main conclusion is that   If you call the    canOpenURL    method on a URL that is not in your whitelist  it will return    NO     even if there is an app installed that has registered to handle this scheme  A    This app is not allowed to query for scheme xxx    syslog entry will appear  If you call the    openURL    method on a URL that is not in your whitelist  it will fail silently  A    This app is not allowed to query for scheme xxx    syslog entry will appear   The author also speculates that this is a bug with the OS and Apple will fix this in a subsequent release

Assuming two apps TestA and TestB  TestB wants to query if TestA is installed   TestA  defines the following URL scheme in its info plist file    lt key gt CFBundleURLTypes lt  key gt   lt array gt       lt dict gt           lt key gt CFBundleURLSchemes lt  key gt           lt array gt               lt string gt testA lt  string gt           lt  array gt       lt  dict gt   lt  array gt    The second app  TestB  tries to find out if  TestA  is installed by calling     UIApplication sharedApplication  canOpenURL  NSURL URLWithString   TestA          But this will normally return NO in iOS9 because  TestA  needs to be added to the LSApplicationQueriesSchemes entry in TestB s info plist file  This is done by adding the following code to TestB s info plist file    lt key gt LSApplicationQueriesSchemes lt  key gt   lt array gt       lt string gt TestA lt  string gt   lt  array gt    A working implementation can be found here  https   github com gatzsche LSApplicationQueriesSchemes-Working-Example

It doesn t seem anyone has addressed how to specify URLs with embedded parameters  Any URL that contains parameters it won t possible to specify the specific URL in LSApplicationsQueriesSchemes    For example  assume I have an email app that passes the the senders email address   myemail   mailto bob gmail com   The only way it seems to get it to work in iOS9 is to remove any parameters

Apple changed the canOpenURL method on iOS 9  Apps which are checking for URL Schemes on iOS 9 and iOS 10 have to declare these Schemes as it is submitted to Apple

Well you can open an app by calling openURL  or openURL options completionHandler   iOS 10 onwards  directly without making the conditional check canOpenURL   Please read the discussion section in Apple doc for canOpenURL  method which says      the openURL  method is not constrained by the LSApplicationQueriesSchemes requirement

It is important to note that there was a bug with jailbroken phones on 9 0 x which broke url schemes   If you re running a jailbroken device then make sure you update Patcyh in Cydia

When I tried to call Facebook from my own app today  I found that there is no a LSApplicationQueriesSchemes key I can add to the Info plist  Xcode Version 8 2 1  8C1002    I opened the Info plist with Sublime Text and manually added it into the file  then it worked  Just to let you know that if you cannot find the key  simply add it yourself

From  Session 703 WWDC 2015      You can continue to use URL schemes when you build your app for iOS 9   and you want to call URL schemes  you will now need to declare them in   your apps Info plist  There is a new key  LSApplicationQueriesSchemes    and here you will need to add the list of schemes you want to are   canOpenURL on

This is a new security feature of iOS 9  Watch WWDC 2015 Session 703 for more information    Any app built with SDK 9 needs to provide a LSApplicationQueriesSchemes entry in its plist file  declaring which schemes it attempts to query    lt key gt LSApplicationQueriesSchemes lt  key gt   lt array gt    lt string gt urlscheme lt  string gt    lt string gt urlscheme2 lt  string gt    lt string gt urlscheme3 lt  string gt    lt string gt urlscheme4 lt  string gt   lt  array gt
