        if([[self.subviews objectAtIndex:i] isKindOfClass:[UITextField class]]) {
            searchField = [self.subviews objectAtIndex:i];
        }
    }
    if(!(searchField == nil)) {
        searchField.textColor = [UIColor whiteColor];
        [searchField.leftView setHidden:YES];
        [searchField setBackground: [UIImage imageNamed:@"SearchBarBackground.png"] ];
