swift - "How to fix ' 链接器命令失败，退出代码为 1(使用 -v 查看调用)'?"

Question

我想使用 Structure SDK 构建非常简单的代码。但是，我得到一个错误(见下文)

代码:

import UIKit
import Foundation

class ViewController: UIViewController {

    override func viewDidLoad() {
        if (myclass.isConnected() == true){
            myTextView.text = "Exist."
        }
        else{
            myTextView.text = "Not Exist!"
        }
    }

    @IBOutlet weak var myTextView: UITextView!

    var myclass = STSensorController()
}

错误:

Undefined symbols for architecture arm64:
  "_OBJC_CLASS_$_STSensorController", referenced from:
      objc-class-ref in ViewController.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

请帮我调试

Answer 1

使用此命令清理代码 shift + option + command + k。如果失败，请确保您的 STSensorController 类在模块中有引用。
