UISearchBar 按钮的文字和颜色更改

设置 取消 按钮的颜色 为 黑色（这个方法是google来的）

[[UIBarButtonItem appearanceWhenContainedIn: [UISearchBar class], nil] setTintColor:[UIColor blackColor]];

至于更改cancel按钮为 “取消”按钮

- (void)searchBarTextDidBeginEditing:(UISearchBar *)hsearchBar
{
    self.searchBar.showsCancelButton = NO;
    for(id searchButton in [self.searchBar subviews])
    {
        if([searchButton isKindOfClass:[UIButton class]])
        {
            [(UIButton *)searchButton setTitle:@"取消"  forState:UIControlStateNormal];
            
        }
    }
}
