当我单击按钮creaX时，我的应用程序崩溃了，控制台显示了以下错误，并且在Thread 1: signal SIGABRT中显示了AppDelegate。我尝试检查按钮是否有可能没有的插座，但没关系，我尝试将按钮与ViewController断开连接，然后重新连接，我尝试再次创建按钮的动作（从插座和视图控制器中删除前一个），但错误仍然在这里：

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.

"<NSLayoutConstraint:0x60c00008d480 UILayoutGuide:0x60c0001bef40'UIViewSafeAreaLayoutGuide'.trailing == UIImageView:0x7f9d19e0ad60.trailing + 92 (active)>",

Will attempt to recover by breaking constraint

Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

出了什么问题？
答案 0 :(得分：0)
此签名是错误的（似乎您在将操作连接到按钮之后更改了参数）
@IBAction func Create(_ signIn: GIDSignIn!, didSignInFor user: GIDGoogleUser!)
应该是
@IBAction func Create(_ sender: UIButton)
您还希望按钮从何处为您提供GIDSignIn的值
&& GIDGoogleUser，它只能自我提供
并重新分配您分享给他们的价值
