UISearchBar appearance issues

[tomleavy]

I have discovered 2 problems in UI7SearchBar. The first one only happens when you add the bar to a view controller programmatically.

1. A white, rounded rect background as seen in iOS7 is applied to the textfield inside the search bar, but it is still drawn with the iOS6 style simultaneously.
2. The current tint color is not reflected in the cancel button after focusing the search bar's text field

iOS6 + UI7Kit iOS7
