Question

我有一个分段控件，可以显示段的自定义图像。我创建了如下

[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOffState"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOnState"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];


[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"on_div"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"off_div"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

CGRect frameSeg= repaymetSegmentedControl.frame;
[repaymetSegmentedControl setFrame:CGRectMake(frameSeg.origin.x, frameSeg.origin.y-5, frameSeg.size.width, frameSeg.size.height + 15)];

在我运行应用程序时，我会根据偏好选择其中一个细分。它如图所示。不知道它有什么问题。

在viewDidLoad中使用此代码给了我一些我认为您正在寻找的结果（我将您的图片重命名为让我更清楚一点）。

    [repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"whiteBG"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [repaymetSegmentedControll setBackgroundImage:[UIImage imageNamed:@"pinkBG"] forState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault];
    [repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"pinkBG"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
    [repaymetSegmentedControl setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor blackColor]} forState:UIControlStateNormal ];
    [repaymetSegmentedControll setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]} forState:UIControlStateHighlighted ];
    [repaymetSegmentedControl setTitleTextAttributes:@{NSForegroundColorAttributeName:[UIColor whiteColor]} forState:UIControlStateSelected ];

    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateHighlighted rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"pinkDivider"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateHighlighted barMetrics:UIBarMetricsDefault];
    [repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"whiteDivider"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

使用此代码，结果如下。附图：

我的猜测是，所选片段的文字颜色设置为黑色和白色。因此，在屏幕截图中，选择了中间片段。

问题可能出在其他地方：

[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOffState"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[repaymetSegmentedControl setBackgroundImage:[UIImage imageNamed:@"-SingleJointOnState"] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

让图像名称以-开头似乎很奇怪。

[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"on_div"] forLeftSegmentState:UIControlStateSelected rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[repaymetSegmentedControl setDividerImage:[UIImage imageNamed:@"off_div"] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

您似乎缺少正确选择/左侧正常选项。

另外，由于您的设计看起来很平坦，我不确定您是否需要其中任何一种。

最后你能把所有的图像都附在问题上了吗？

您的线段分割线图像应与背景图像的高度相同。

为什么其中一个段在分段控件上显示为禁用？
