使UISegmentedControl的段分隔符变暗

Question

我有一个分段控件，它有三个按钮，我想要将分隔线条的线条变暗。

我的代码是：

NSArray *listArray = [NSArray arrayWithObjects:@"Email",@"SMS",nil];
UISegmentedController *segmentedController = [[UISegmentedControl alloc] initWithItems:listArray]; 
segmentedController.segmentedControlStyle = UISegmentedControlStyleBar;//i have to use this style(bar) 
segmentedController.momentary = YES; 
segmentedController.frame = CGRectMake (90, CGRectGetMaxY(lbl.frame)+50, 140, 40); 
//seg.tintColor = [UIColor redColor]; 
[segmentedController addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged]; 
[self.view addSubview:segmentedController];
