Question

我想为UISegmentedControl的文本和背景设置颜色。所以我要设置四种颜色，文本和背景的默认和选定颜色。

我可以使用tintColor和backgroundColor来设置背景。但是如何设置默认文本颜色，与色调颜色不一样？

注意：这里是swift3而不是旧语言。我是ios的初学者，我刚从swift3开始，没有前一种语言的经验。

任何帮助将不胜感激。

 //ProfilePage     
 loginFB(){
    this.usersService
        .registerUserFb()
        .then(()=>{
             this.usersService.getUserFacebook().subscribe((userObject) => {
                this.user = userObject;
             });
        });
 }


//users.services.ts
registerUserFb(){
    return new Promise(resolve => {
      Facebook.login(['email']).then((response) => {
         Facebook.getLoginStatus().then((response) => {

            if(response.status == 'connected'){
               this.checkIfUserExists(response.authResponse.userID);
               resolve();
            }

         });
      });
    });
}

快速4 代码为您的UISegmentedControl（在下面的示例中为sc）更新文本颜色：

// selected option color
sc.setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.green], for: .selected)

// color of other options
sc.setTitleTextAttributes([NSAttributedStringKey.foregroundColor: UIColor.white], for: .normal)

Answer 3

customSC.backgroundColor= UIColor（red: 0.5, greep: 0.5, blue: 0.5, alpha: 1.0）
customSC.tintColor= UIColor（red: 0.5, greep: 0.5, blue: 0.5, alpha: 1.0）

Answer 4

这是可行的：

    //default background color
    customSC.backgroundColor = UIColor(red:65/255.0, green:140/255.0, blue:218/255.0, alpha: 1.0)

    //selected background color
    customSC.tintColor = UIColor(red:65/255.0, green:140/255.0, blue:218/255.0, alpha: 1.0)

    //selected title text color
    customSC.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.white], for: UIControlState.selected)

    //default title text color
    customSC.setTitleTextAttributes([NSForegroundColorAttributeName: UIColor.darkGray], for: UIControlState.normal)

Answer 5

Swift 4.2 +

segmentedControl.tintColor = .black //background
segmentedControl.setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.white], for: .selected)
segmentedControl.setTitleTextAttributes([NSAttributedString.Key.foregroundColor: UIColor.red], for: .normal)

Swift3如何为UISegmentedControl设置默认文本颜色？
