我如何重写下面的代码？
self.view.frame = CGRectOffset(self.view.frame,movement)
‘Offset’ has been replaced by ‘offsetby’
当我用所谓的“解决方案”替换它时：
self.view.frame = CGRect.offsetby(self.view.frame,movement)
我收到一个错误：
“Instance member ‘offsetBy’ cannot be used on type ‘CGRect’; did you mean to use a value of this type instead?”
解决方法
您必须在CGRect的实例上调用offsetBy.
self.view.frame = self.view.frame.offsetBy(dx: 0,dy: movement)
