Solution in Swift 3:

In Swift 2 and iOS 9 you can call:

UITextField.appearanceWhenContainedInInstancesOfClasses([UISearchBar.self]).backgroundColor = UIColor.darkGrey()

Swift 3:

UITextField.appearance(whenContainedInInstancesOf: [UISearchBar.self]).backgroundColor = UIColor.darkGrey()

for (UIView *subView in _searchBar.subviews) {
    for(id field in subView.subviews){

            [textField setBackgroundColor:[UIColor grayColor]];
