Minimize & Reopen app hangs the UI for 5-8 seconds

[fparkar]

This lib have a big issue especially iPhone 6 onwards.

Follow steps to view this issue.

1. Minimize app.
2. Lock phone
3. Un-lock phone
4. Open app
5. Click on any UIButton or tableview and go to another view controller. Going to another view controller is most important. It will hang for some time and after some time, app will go to another viewcontroller.

**Note : If you log the click event, you will see the logs when you click, but transition is done after 5-8 seconds. Even I try to put transition to another view controller with dispatch_async(dispatch_get_main_queue(), ^{ but still UI hangs.
