如何设置UIButton的标题文字颜色?

[英]How to set the title text color of UIButton?

I tried changing the colors of the text for a button, but it's still staying white.我尝试更改按钮文本的 colors,但它仍然保持白色。

isbeauty = UIButton()
isbeauty.setTitle("Buy", forState: UIControlState.Normal)
isbeauty.titleLabel?.textColor = UIColorFromRGB("F21B3F")
isbeauty.titleLabel!.font = UIFont(name: "AppleSDGothicNeo-Thin" , size: 25)
isbeauty.backgroundColor = UIColor.clearColor()
isbeauty.layer.cornerRadius = 5
isbeauty.layer.borderWidth = 1
isbeauty.layer.borderColor = UIColorFromRGB("F21B3F").CGColor
isbeauty.frame = CGRectMake(300, 134, 55, 26)
isbeauty.addTarget(self,action: "first:", forControlEvents: UIControlEvents.TouchUpInside)
self.view.addSubview(isbeauty)

I also tried changing it the red, black, blue, but nothing is happening.我也尝试将其更改为红色、黑色、蓝色,但没有任何反应。

You have to use func setTitleColor(_ color: UIColor?, for state: UIControlState) the same way you set the actual title text.您必须以与设置实际标题文本相同的方式使用func setTitleColor(_ color: UIColor?, for state: UIControlState) Docs 文档

isbeauty.setTitleColor(UIColorFromRGB("F21B3F"), for: .normal)

Swift UI solution Swift UI解决方案

Button(action: {}) {
            Text("Button")
        }.foregroundColor(Color(red: 1.0, green: 0.0, blue: 0.0))

to improve comments.以改进评论。 This should work:这应该有效:

button.setTitleColor(.red, for: .normal)

设置按钮标题颜色的示例

btnDone.setTitleColor(.black, for: .normal)

This is swift 5 compatible answer.这是 swift 5 兼容的答案。 If you want to use one of the built-in colours then you can simply use如果你想使用其中一种内置颜色,那么你可以简单地使用

button.setTitleColor(.red, for: .normal)

If you want some custom colours, then create an extension for a UIColor as below first.如果你想要一些自定义颜色,那么首先为 UIColor 创建一个扩展,如下所示。

import UIKit
extension UIColor {
    static var themeMoreButton = UIColor.init(red: 53/255, green: 150/255, blue: 36/255, alpha: 1)
}

Then use it for your button as below.然后将其用于您的按钮,如下所示。

button.setTitleColor(UIColor.themeMoreButton, for: .normal)

Tip: You can use this method to store custom colours from rgba colour code and reuse it throughout your application.提示:您可以使用此方法存储来自 rgba 颜色代码的自定义颜色,并在整个应用程序中重复使用。

func setTitleColor(_ color: UIColor?, for state: UIControl.State)

Parameters :参数

color:颜色:
The color of the title to use for the specified state.用于指定状态的标题颜色。

state:状态:
The state that uses the specified color.使用指定颜色的状态。 The possible values are described in UIControl.State. UIControl.State 中描述了可能的值。

Sample :样品

let MyButton = UIButton()
MyButton.setTitle("Click Me..!", for: .normal)
MyButton.setTitleColor(.green, for: .normal)

referring to radio buttons ,you can also do it with Segmented Control as following:参考单选按钮,您也可以使用 Segmented Control 执行以下操作:

step 1: drag a segmented control to your view in the attribute inspector change the title of the two segments ,for example "Male" and "Female"第 1 步:在属性检查器中将分段控件拖到您的视图中,更改两个分段的标题,例如“男”和“女”

step 2: create an outlet & an action for it in the code第 2 步:在代码中为它创建一个插座和一个动作

step 3: create a variable for future use to contain choice's data第 3 步:创建一个变量以供将来使用以包含选择的数据

in the code do as following:在代码中执行以下操作:

@IBOutlet weak var genderSeg: UISegmentedControl!

var genderPick : String = ""


 @IBAction func segAction(_ sender: Any) {

    if genderSeg.selectedSegmentIndex == 0 {
         genderPick = "Male"
        print(genderPick)
    } else if genderSeg.selectedSegmentIndex == 1 {
        genderPick = "Female"
          print(genderPick)
    }
}

设置标题颜色

btnGere.setTitleColor(#colorLiteral(red: 0, green: 0, blue: 0, alpha: 1), for: .normal)

您可以使用十六进制代码设置 UIButton 标题颜色

btn.setTitleColor(UIColor(hexString: "#95469F"), for: .normal)

if you are using a button without NSAttribute then you can simply set the title and color of button by using如果您使用的是没有 NSAttribute 的按钮,那么您可以简单地通过使用设置按钮的标题和颜色

yourButtonName.setTitle("Your Title", for: .normal)

enterCustomAmount.setTitleColor(.gray, for: .normal)

but if you give NSAttribute in your button property then you first need to set the attribute for the button但是如果你在你的按钮属性中给出 NSAttribute 那么你首先需要为按钮设置属性

var myAttribute = [ NSAttributedString.Key.foregroundColor: UIColor.init(hexString: "#FFAEA9")]

or for more then one property you can use comma separator like或者对于多个属性,您可以使用逗号分隔符,例如

var myAttribute = [ NSAttributedString.Key.foregroundColor: UIColor.init(hexString: "#FFAEA9"), NSAttributedString.Key.font: UIFont(name: "Dubai-Medium", size: 16) ]

and assign it to your UIButton like this并像这样将其分配给您的 UIButton

 let myString = "Your title"
            let text = NSAttributedString(string: myString, attributes: myAttribute)
            enterCustomAmount.setAttributedTitle(text, for: .normal)

To change color of text更改文本颜色

button.titleLabel.textColor = UIColor.grayColor()

To change state, on button press add following -要更改 state,请在按下按钮时添加以下内容 -

button.enabled = true

IBAction method should be like - IBAction 方法应该像 -

@IBAction func buttonTapped(sender : UIButton!) {
    sender.enabled = false
}
