UIWebView leaks, JS Garbage Collector & WebCore VMs

Question

I\'ve been building a browser feature for an app which obviously works with UIWebView. I\'ve been seeing memory jump up when the browser opens which makes sense, however i\'m se

Answer 1

I'm unsure if I would immediately consider this a problem. Those VMs only start when you add a web view to your view hierarchy and load a request with it.

It may just be the OS that keeps those resources alive in case they will be used again.

I tried to replicate your code that cleans up the data and had drops of 50%.

The JS Garbage collector was always at around 3MB minimum, but had maximums of 8MB The WebCore purgeable data was always at around 700KB

You may also consider that this may be related to bad JavaScript that continues to live because of leaks in the JavaScript code.
