自定义UISearchDisplayController

alt text http://img527.imageshack.us/img527/9775/searchdisplaycontrollerz.png

我可以通过一种黑客代码来改变分段控制:

- (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;
        }           
    }
}}

不管这些按钮有多大,我怎么能把它修好,让它们和原来一样漂亮呢?

尽管我尝试了每种分段控制方式,但我还是无法使按钮变小。下面是我需要使用的代码,至少要在IOS4上使色调正确:

- (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;
                }
            }                       
        }
    }
}

- (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]; }
