苹果账号登录 – sign in with apple

参考网址：https://www.wangquanwei.com/560.html

配置设置：

1.在 Xcode 里的 Signing & Capabilities 开启 Sign in with Apple 功能

2.添加完 Sign In With Apple

国际化配置（针对 ASAuthorizationAppleIDButton）

本地化中文显示info设置：

核心代码：

登录按钮：建议使用苹果提供的，以免格式不符合，审核被拒
需要导入头文件 AuthenticationServices

import AuthenticationServices

if #available(iOS 13.0, *) {
    let apLoginBtn = ASAuthorizationAppleIDButton(authorizationButtonType: .signIn, authorizationButtonStyle: .whiteOutline)
    self.view.addSubview(apLoginBtn)
    apLoginBtn.addTarget(self, action: #selector(appleLogin), for: .touchUpInside)
    apLoginBtn.snp.makeConstraints { (maker) in
        maker.bottom.equalTo(otherLoginBtn!.snp.top).offset(-25)
        maker.centerX.equalToSuperview()
        maker.width.equalTo(300)
        maker.height.equalTo(50)
    }
    apLoginBtn.layoutIfNeeded()
    apLoginBtn.cornerRadius = 25
}
