代码：
registerButton.addTarget(self, action: Selector("registerAction"), forControlEvents: UIControlEvents.TouchUpInside) |
警告：
Use ‘#selector’ instead of explicitly constructing a ‘Selector’
改为：
// registerButton.addTarget(self, action: Selector("registerAction"), forControlEvents: UIControlEvents.TouchUpInside) registerButton.addTarget(self, action: #selector(RegisterUsernameViewController.registerAction), forControlEvents: UIControlEvents.TouchUpInside) |
即可。
还有类似的问题：
代码：
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: "dismissKeyboard") self.view.addGestureRecognizer(tap) |
警告：
Use of string literal for Objective-C selectors is deprecated; use ‘#selector’ instead
改为：
let tap: UITapGestureRecognizer = UITapGestureRecognizer(target: self, action: #selector(LoginViewController.dismissKeyboard)) |
即可。
