I am going to continue and assume that you are writing your code based on this thread:
Add a UIView over all other views, including the StatusBar
As the saying goes, why do you install:
statusWindow.windowLevel = UIWindowLevelStatusBar + 1;
It should be:
statusWindow.windowLevel = UIWindowLevelStatusBar;
In the future, add links to any topics you have looked at.
Good luck
