setting background image of UISegmentedControl
提问by adit
So I have the following code to set the segmented control background color:
所以我有以下代码来设置分段控件背景颜色：
UISegmentedControl * segmentedCtrl = [[UISegmentedControl alloc] initWithFrame:CGRectMake(0, 0, 150, 35)];
[segmentedCtrl setBackgroundImage:[UIImage imageNamed:@"btn-gradient-brown"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[segmentedCtrl setBackgroundImage:[UIImage imageNamed:@"btn-gradient-brown"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
[segmentedCtrl insertSegmentWithImage:[UIImage imageNamed:@"icon-home.png"] atIndex:0 animated:NO];
[segmentedCtrl insertSegmentWithImage:[UIImage imageNamed:@"icon-star.png"] atIndex:1 animated:NO];
It all works fine except that when I click on the segment I can see the blue button highlighted. How do I disable this highlight? Here's a screenshot of my problem:
一切正常，只是当我单击该段时，我可以看到突出显示的蓝色按钮。如何禁用此突出显示？这是我的问题的屏幕截图：

UISegmentControl has a Divider between two segments. By using the following code you can change the divider background.
UISegmentControl 在两个段之间有一个分隔符。通过使用以下代码，您可以更改分隔线背景。
[segmentedCtrl setDividerImage:[UIImage imageNamed:@"divider_selected.png"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[segmentedCtrl setDividerImage:[UIImage imageNamed:@"divider_normal.png"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
Where divider_selected.png is a image which you used for selected state. Where as divider_normal.png is a image which you used for normal state.
其中divider_selected.png 是您用于选定状态的图像。其中divider_normal.png 是您用于正常状态的图像。
Hope this will help....

Set your same background images for the highlighted state:
为突出显示的状态设置相同的背景图像：
[segmentedCtrl setBackgroundImage:[UIImage imageNamed:@"btn-gradient-brown"] forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault];
