Question

所以我有以下代码来设置分割控制背景颜色:

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];

一切正常, 除了当我点击段段时, 我可以看到蓝色按钮被突出显示。我如何禁用此突出显示? 这里截图显示我的问题 :

Answer 1

UISEGENT 控制在两个区段之间有一个分隔符。使用以下代码, 您可以更改分隔符背景。

[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];

分隔符_ sective. png 是您用于选定状态的图像。分隔符_ normal. png 是您用于正常状态的图像。

希望这能帮上忙...

为突出显示状态设置相同的背景图像 :

[segmentedCtrl setBackgroundImage:[UIImage imageNamed:@"btn-gradient-brown"] forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault];
