Font rendering issue on iOS mobile devices

I have one problem what find only on iOS and don't know to solve.
On image above you can see checkmark list where is complete font bad rendered and pixelate. I don't know why and how to solve this. I try various things from transform and text-rendering options to shaddow tricks.
I realy need help on this. Thanks!
I think -webkit-font-smoothing is the culprit here; -webkit-font-smoothing:none looks pretty bad on my iPhone 6s.
Christoph Zillgens has a really good test page for -webkit-font-smoothing which shows this clearly.

Angular-meteor tutorial WhatsApp is not working in IOS 9.3

I'm trying to deploy Whatsapp tutorial application shown in this page (http://www.angular-meteor.com/tutorials/whatsapp/meteor/layout) in IOS 9.3, but I'm not able to run properly due to a navigation problem. The behaviour is very weird, you have to click more than one time an action button in order to navigate to other page. Also, the icons in the tab control are not visible.

Anyone know where to find the -(void)lock in iOS 7 so I can hook into it?

As stated, I am trying to figure out what header in the iOS 7 Springboard that holds -(void)lock{
In earlier versions of iOS there was a SBAwayController that held this, but Apple apparently has decided to change the way it does things again... I have scoured threw the SB headers for hours and hours and have come up with a whole lot of nothing. I did however find some other interesting things like how to make the screen flash with any given color or how to bring the user back to the lockscreen.
Any and all help would be greatly appreciated thank you!!!

iPad Drawing Issue?

We are trying to develop a ipad app that allows the user to draw on an image, and then save the data for later editing as well. Some issues we are facing given in the document, http://bit.ly/dJgwhZ. Any help will be greatly appreciated.
Thanks.
I think you would greately benefit from looking at this sample code; it is called GL paint. It does most of what you want to do, you just need to implement the photo as background and saving to the library.
Hope it helps!
