我能够通过一种 hack 代码更改分段控件：

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
for (UIView *subview in self.view.subviews) {
    for (UIView *subview2 in subview.subviews) {
        if ([subview2 isKindOfClass:[UISegmentedControl class]]) {
            UISegmentedControl *segmentedControl = (UISegmentedControl *)subview2;
            segmentedControl.tintColor = [UIColor blackColor];
            segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar;
        }           
    }
}}

然而按钮是巨大的，我怎样才能修复它，让它们和原来的一样漂亮？

我可以使用以下代码自定义表格视图：

- (void)searchDisplayController:(UISearchDisplayController *)controller willShowSearchResultsTableView:(UITableView *)tableView {
tableView.backgroundColor = [UIColor colorWithRed:(19.0 / 255.0) green:(19.0 / 255.0) blue:(19.0 / 255.0) alpha:1.0];
tableView.separatorColor  = [UIColor blackColor]; }

但是，当您触摸取消按钮时，界面会在返回原始 tableview 之前闪烁白色。如何解决这个问题？

尽管尝试了每个分段控制样式，但我也永远无法让按钮变小。这是我需要用来至少在 IOS4 上获得正确色调的代码：

- (void)searchDisplayControllerWillBeginSearch:(UISearchDisplayController *)controller {
    static BOOL tintAlreadyChanged = NO;
    if (tintAlreadyChanged) return;

    NSLog(@"Searching subViews for UISegmentControl:");
    //fix segmented control
    for (UIView *subview in self.view.subviews) {
        //NSLog(@"\n\nsubView = %@",subview);
        for (UIView *subview2 in subview.subviews) {
            //NSLog(@"subView2 = %@",subview2);
            for (UIView *subview3 in subview2.subviews) {
                //NSLog(@"subView3 = %@",subview3);
                if ([subview3 isKindOfClass:[UISegmentedControl class]]) {
                    NSLog(@"Found UISegment SubView = %@",subview3);
                    UISegmentedControl *segmentedControl = (UISegmentedControl *)subview3;
                    segmentedControl.tintColor = [UIColor blackColor];
                    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBezeled;
                    tintAlreadyChanged = YES;
                }
            }                       
        }
    }
}
