ios 完全删除 UISegmentedControl 分隔符。（苹果手机）

Remove UISegmentedControl separators completely. (iphone)

提问by Kazmi

Is there a way to completely remove the line separating the two segments in a UISegmentedControl?

有没有办法完全删除 UISegmentedControl 中分隔两个段的线？

Setting the segmentedControlStyleis not helping.

设置segmentedControlStyle没有帮助。

No, there is not. You should look into creating the UISegmentedControl functionality manually. Maybe use two UIButtons.

不，那里没有。您应该考虑手动创建 UISegmentedControl 功能。也许使用两个 UIButton。

EDITED:-Swift 3.0extensions

编辑：- Swift 3.0扩展

    extension UISegmentedControl {

    func customizeAppearance(for height: Int) {

        setTitleTextAttributes([NSFontAttributeName:UIFont(name:"Helvetica Neue", size:13.0)!,NSForegroundColorAttributeName:UIColor.white], for:.normal)
        setTitleTextAttributes([NSFontAttributeName:UIFont(name:"Helvetica Neue", size:13.0)!,NSForegroundColorAttributeName:UIColor.white], for:.selected)
        setDividerImage(UIImage().colored(with: .clear, size: CGSize(width: 1, height: height)), forLeftSegmentState: .normal, rightSegmentState: .normal, barMetrics: .default)
        setBackgroundImage(UIImage().colored(with: .clear, size: CGSize(width: 1, height: height)), for: .normal, barMetrics: .default)
        setBackgroundImage(UIImage().colored(with: UIColor.init(red: 215/255.0, green: 0.0, blue: 30/255.0, alpha: 1.0), size: CGSize(width: 1, height: height)), for: .selected, barMetrics: .default);

        for  borderview in subviews {
            let upperBorder: CALayer = CALayer()
            upperBorder.backgroundColor = UIColor.init(red: 215/255.0, green: 0.0, blue: 30/255.0, alpha: 1.0).cgColor
            upperBorder.frame = CGRect(x: 0, y: borderview.frame.size.height-1, width: borderview.frame.size.width, height: 1)
            borderview.layer.addSublayer(upperBorder)
        }

    }
}

extension UIImage {

    func colored(with color: UIColor, size: CGSize) -> UIImage {
        UIGraphicsBeginImageContext(size)
        let context = UIGraphicsGetCurrentContext()
        context!.setFillColor(color.cgColor);
        let rect = CGRect(origin: CGPoint(x: 0, y: 0), size: size)
        context!.fill(rect);
        let image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        return image!
    }
}

The UIImageextension generates a colored image with desired size.

该UIImage扩展程序生成具有所需大小的彩色图像。

Forcing the heightparameter in customizeAppearanceavoid any crash when building the context.

强制height参数在customizeAppearance构建时要避免任何崩溃context。

You can make it even more reusable by extracting each customization attribute and put it as function's parameters ;)

您可以通过提取每个自定义属性并将其作为函数的参数来使其更具可重用性；)

Here is sample code, tested over iOS 9 and works fine for me.

这是示例代码，在 iOS 9 上测试过，对我来说效果很好。

Add these lines of code in viewDidLoad-

将这些代码行添加到viewDidLoad-

[yourSegmentControl setTitleTextAttributes:@{ NSFontAttributeName:[UIFont fontWithName:@"Roboto-black" size:13.0],NSForegroundColorAttributeName:[UIColor whiteColor] }forState:UIControlStateSelected];

[yourSegmentControl setTitleTextAttributes:@{ NSFontAttributeName:[UIFont fontWithName:@"Roboto-black" size:13.0],NSForegroundColorAttributeName:[UIColor whiteColor] }forState:UIControlStateNormal];

[yourSegmentControl setDividerImage:[self imageWithColor:[UIColor clearColor]] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

[yourSegmentControl setBackgroundImage:[self imageWithColor:[UIColor clearColor]] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

[yourSegmentControl setBackgroundImage:[self imageWithColor:[UIColor colorWithRed:215/255.0 green:0 blue:30/255.0 alpha:1.0]] forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];

for (UIView *borderview in yourSegmentControl.subviews) {

    CALayer *upperBorder = [CALayer layer];

    upperBorder.backgroundColor = [UIColor colorWithRed:215/255.0 green:0 blue:30/255.0 alpha:1.0].CGColor;

    upperBorder.frame = CGRectMake(0, borderview.frame.size.height-1, borderview.frame.size.width, 1.0f);

    [borderview.layer addSublayer:upperBorder];
}

and

和

- (UIImage *)imageWithColor:(UIColor *)color {
    CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();

    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}

Here is the Swiftextension for achieving same view in Swift-

这里是斯威夫特扩展在Swift-实现同样的观点

yourSegmentControl.setTitleTextAttributes([NSFontAttributeName:UIFont(name:"Helvetica Neue", size:13.0)!,NSForegroundColorAttributeName:UIColor.whiteColor()], forState:UIControlState.Normal)

yourSegmentControl.setDividerImage(self.imageWithColor(UIColor.clearColor()), forLeftSegmentState: UIControlState.Normal, rightSegmentState: UIControlState.Normal, barMetrics: UIBarMetrics.Default)

yourSegmentControl.setBackgroundImage(self.imageWithColor(UIColor.clearColor()), forState:UIControlState.Normal, barMetrics:UIBarMetrics.Default)

yourSegmentControl.setBackgroundImage(self.imageWithColor(UIColor.init(red: 215/255.0, green: 0.0, blue: 30/255.0, alpha:1.0)), forState:UIControlState.Selected, barMetrics:UIBarMetrics.Default);

for  borderview in yourSegmentControl.subviews {

let upperBorder: CALayer = CALayer()
upperBorder.backgroundColor = UIColor.init(red: 215/255.0, green: 0.0, blue: 30/255.0, alpha: 1.0).CGColor
upperBorder.frame = CGRectMake(0, borderview.frame.size.height-1, borderview.frame.size.width, 1.0);
borderview.layer .addSublayer(upperBorder);

}

and

和

func imageWithColor(color: UIColor) -> UIImage {

    let rect = CGRectMake(0.0, 0.0, 1.0, yourSegmentControl.frame.size.height)
    UIGraphicsBeginImageContext(rect.size)
    let context = UIGraphicsGetCurrentContext()
    CGContextSetFillColorWithColor(context, color.CGColor);
    CGContextFillRect(context, rect);
    let image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    return image

}

Use this method to change your segment divider image:

使用此方法更改您的分段分隔符图像：

[segmentControl setDividerImage:dividerimg
            forLeftSegmentState:UIControlStateNormal
              rightSegmentState:UIControlStateNormal
                     barMetrics:UIBarMetricsDefault];

I combined the previous answers into a Swiftextension.

我将之前的答案组合成一个Swift扩展。

I wanted to remove all borders and dividers. This code just uses the normal segment colors, e.g. tint and background for selected / deselected.

我想删除所有边框和分隔线。此代码仅使用正常的段颜色，例如选中/取消选中的色调和背景。

Call

称呼

segmentedControl.removeBorders()

Here's the extension

这是扩展名

extension UISegmentedControl {
    func removeBorders() {
        setBackgroundImage(imageWithColor(backgroundColor!), forState: .Normal, barMetrics: .Default)
        setBackgroundImage(imageWithColor(tintColor!), forState: .Selected, barMetrics: .Default)
        setDividerImage(imageWithColor(UIColor.clearColor()), forLeftSegmentState: .Normal, rightSegmentState: .Normal, barMetrics: .Default)
    }

    // create a 1x1 image with this color
    private func imageWithColor(color: UIColor) -> UIImage {
        let rect = CGRectMake(0.0, 0.0, 1.0, 1.0)
        UIGraphicsBeginImageContext(rect.size)
        let context = UIGraphicsGetCurrentContext()
        CGContextSetFillColorWithColor(context, color.CGColor);
        CGContextFillRect(context, rect);
        let image = UIGraphicsGetImageFromCurrentImageContext();
        UIGraphicsEndImageContext();
        return image
    }
}

The following code will do exactly what you want.

以下代码将完全符合您的要求。

UIGraphicsBeginImageContextWithOptions(CGSizeMake(1, self.segControlOut.frame.size.height), NO, 0.0);
UIImage *blank = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
[self.segControlOut setDividerImage:blank
                forLeftSegmentState:UIControlStateNormal
                  rightSegmentState:UIControlStateNormal
                         barMetrics:UIBarMetricsDefault];

You can remove all background, border and separators from a UISegmentedControl by setting a black image. Or you can set custom colours.

您可以通过设置黑色图像从 UISegmentedControl 中删除所有背景、边框和分隔符。或者您可以设置自定义颜色。

The below example removes all borders/seperators, and sets the background to be white with 0.2 alpha, and the selected segment to be white with alpha 1.0

下面的示例删除所有边框/分隔符，并将背景设置为 0.2 alpha 的白色，并将所选部分设置为 alpha 1.0 的白色

[self.segmentedControl setBackgroundImage:[self imageWithColor:[UIColor colorWithWhite:1.0 alpha:0.2]] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[self.segmentedControl setBackgroundImage:[self imageWithColor:[UIColor colorWithWhite:1.0 alpha:1.0]] forState:UIControlStateSelected  barMetrics:UIBarMetricsDefault];

- (UIImage *)imageWithColor:(UIColor *)color {
    CGRect rect = CGRectMake(0.0f, 0.0f, 1.0f, 1.0f);
    UIGraphicsBeginImageContext(rect.size);
    CGContextRef context = UIGraphicsGetCurrentContext();

    CGContextSetFillColorWithColor(context, [color CGColor]);
    CGContextFillRect(context, rect);

    UIImage *image = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return image;
}

I have used segmentcontrol.tintColor = [UIColor clearColor];with iOS7 and it seems to work.

我用过segmentcontrol.tintColor = [UIColor clearColor];iOS7，它似乎工作。
