Date picker causes crash

[nfranke]

Run the demo, select the calendaring event item (first one). Click "starts" and then click the row again to hide. Click the cancel button. Click "Text Field Examples" in the main screen. It will crash all the time in the simulator. Both 32 and 64 bits iOS 7.1

Instruments flags this as: An Objective-C message was sent to a deallocated 'CALayer' object (zombie) at address: 0x10b69e170.

@nfranke Thanks for reporting this issue.
I think we should remote this: line of code

I will add the fix on v1.0.1.
