How to set the title text color of UIButton?
提问by coolmac
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颜色，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。

This is swift 5 compatible answer. If you want to use one of the built-in colours then you can simply use
这是 swift 5 兼容的答案。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。

referring to radio buttons ,you can also do it with Segmented Control as following:
参考单选按钮，您也可以使用分段控制来执行以下操作：
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)
}
}
