Disable App Transport Security in iOS 9
<!--
This disables app transport security and allows non-HTTPS requests.
Note: it is not recommended to use non-HTTPS requests for sensitive data. A better
approach is to fix the non-secure resources. However, this patch will work in a pinch.
To apply the fix in your Ionic/Cordova app, edit the file located here:
platforms/ios/MyApp/MyApp-Info.plist
And add this XML right before the end of the file inside of the last </dict> entry:

What forces layout/reflow. The comprehensive list.

What forces layout / reflow

All of the below properties or methods, when requested/called in JavaScript, will trigger the browser to synchronously calculate the style and layout*. This is also called reflow or layout thrashing, and is common performance bottleneck.

Generally, all APIs that synchronously provide layout metrics will trigger forced reflow / layout. Read on for additional cases and details.

Element APIs

Getting box metrics
  • elem.offsetLeft, elem.offsetTop, elem.offsetWidth, elem.offsetHeight, elem.offsetParent
