-------------------------------------
Summary: iOS WebView's height becomes greater than screen height
after dismissing the presented ViewController
Key: CB-12478
URL: https://issues.apache.org/jira/browse/CB-12478
Project: Apache Cordova
Issue Type: Bug
Components: Plugin Battery Status, Plugin Camera
Environment: iOS
Reporter: Michael Capulong
The combination of PRs for CB-10158 and CB-11191 has created this scenario.
Versions involved:
# cordova-plugin-statusbar - 2.2.1
# cordova-plugin-camera - 2.3.1 and below
When the camera plugin view controller is dismissed in line 548
*
https://github.com/apache/cordova-plugin-camera/blob/rel/2.3.1/src/ios/CDVCamera.m#L548,
the cordovaViewWillAppear method is called. This happens because
cordovaViewWillAppear was registered to listen for
"CDVViewWillAppearNotification" events
*
https://github.com/apache/cordova-plugin-statusbar/blob/rel/2.2.1/src/ios/CDVStatusBar.m#L120.
The method cordovaViewWillAppear calls resizeWebView. When resizeWebView
reaches line 473
*
https://github.com/apache/cordova-plugin-statusbar/blob/rel/2.2.1/src/ios/CDVStatusBar.m#L473,
all of statusBarFrame's members are set to zeroes. The app then proceeds with
lines 476 and 480
*
https://github.com/apache/cordova-plugin-statusbar/blob/rel/2.2.1/src/ios/CDVStatusBar.m#L476
*
https://github.com/apache/cordova-plugin-statusbar/blob/rel/2.2.1/src/ios/CDVStatusBar.m#L480
and this results in frame.origin.y being assigned the value of 20.
Then in line 485, the frame.size.height gets the value of -20
*
https://github.com/apache/cordova-plugin-statusbar/blob/rel/2.2.1/src/ios/CDVStatusBar.m#L485.
The negative height of the frame causes the the WebView to increase its height
beyond the screen by 20 units.
