-----------------------------

             Summary: iOS application crashes when InAppBrowser is opened and quickly closed
                 Key: CB-4995
                 URL: https://issues.apache.org/jira/browse/CB-4995
             Project: Apache Cordova
          Issue Type: Bug
          Components: Plugin InAppBrowser
    Affects Versions: 3.0.0, 2.9.0, 2.8.0, 2.7.0
         Environment: iOS
            Reporter: Hyong Kim


I personally experienced the issue with 2.8.15, but it appears others are seeing the same
problem even on version 3. Just now, I quickly took a look at the latest version 3 source
code, and it is likely that the issue is still around. That is, I had identified the cause
of the crash and we fixed it in our app.

The issue is presented when a user rapidly opens and closes InAppBrowser while using Cordova
iOS application because (referring to the latest CDVInAppBrowser.m as of 10/3/2013 with commit
hash of a001cffc30cf94cb406128f7b68d143e2cd62114) self.inAppBrowserViewController (line: 332)
is nil if 'browserExit' (line: 353) is called before 'webViewDidFinishLoad' (line: 328) is
invoked.

We put our own patch around line 332 as below, and didn't experience the crash any more with
2.8.15

if (self.inAppBrowserViewController != nil) {
    url = [self.inAppBrowserViewController.currentURL absoluteString];  
} else {
    url = @"";
}
