I'm looking into this issue https://issues.apache.org/jira/browse/CB-11178
The problem is on iOS 9 you can no longer query for schemes unless you add them to the info.plist under the LSApplicationQueriesSchemes key. When the inAppBrowser plugin is called with _system option this code is called: *- (**void**)openInSystem:(**NSURL***)url* *{* *if** ([[**UIApplication* *sharedApplication**] **canOpenURL**:url]) {* * [[**UIApplication* *sharedApplication**] **openURL**:url];* * } **else** { **// handle any custom schemes to plugins* * [[**NSNotificationCenter* *defaultCenter**] **postNotification**:[* *NSNotification* *notificationWithName**:* *CDVPluginHandleOpenURLNotification* *object**:url]];* * }* *}* So, it fails on iOS 9 as fb scheme is not in the info.plist I have 3 options here: 1. Document that on iOS 9 you have to add the urls to the info.plist 2. Document that you don't need inAppBrowser plugin to open a 3rd party app, you just need to use an a tag element with the url scheme on the href 3. Change the code to *- (**void**)openInSystem:(**NSURL***)url* *{* * [[**UIApplication* *sharedApplication**] **openURL**:url];* *}* This will open the app without querying, but we miss the else. I'm not sure why that code is there or if it's used anywhere, it's been there since the beginning of the github repo, it sends a notification with the url scheme in case some other plugin can do something with the url scheme, but I don't think it makes much sense as you are trying to open an external app and that code is to handle the url inside the app. So, opinions?
