 # LSApplicationQueriesSchemes-Working-Example
-iOS 9 introduces LSApplicationQueriesSchemes to allow apps to query if other apps are installed. This project provides two sample apps which are querying for each other. To the moment I didn't get this example run. Thus I use these two apps to communicate with Apple and others.
+iOS 9 introduces LSApplicationQueriesSchemes to allow apps to query if other apps are installed. This project provides two sample apps TestA and TestB which are querying for each other. 
+
+In its info.plist file TestA defines the following URL schemes: 
+
+'''
+<key>CFBundleURLSchemes</key>
+<array>
+  <string>testA</string>
+</array>
+'''
+
+TestB wants to check if TestA is installed by calling
+
+'''
+BOOL canBeOpened = [[UIApplication sharedApplication] 
+                   canOpenURL:[NSURL URLWithString:@"TestA.scheme2://"]];
+'''
+
+This is normally not allowed in iOS9. But by adding the following code to TestB's info.plist file, the query will return YES:
+
+'''
+<key>LSApplicationQueriesSchemes</key>
+<array>
+  <string>TestA</string>
+</array>
+'''
