我正在尝试检查枚举的情况，该枚举具有每个情况的关联值，如下所示：
enum status {
case awake(obj1)
case sleeping(obj2)
case walking(obj3)
case running(obj4)
}
我正在使用if（status==deviceStatus.清醒）{检查状态大小写并收到错误：二进制运算符'=='不能应用于'status'和'（oby1）类型的操作数-
您可以使用if case.清醒=deviceStatus检查deviceStatus是否设置为清醒枚举值：
class Obj1 { }
class Obj2 { }
class Obj3 { }
class Obj4 { }
enum Status {
case awake(Obj1)
case sleeping(Obj2)
case walking(Obj3)
case running(Obj4)
}
let deviceStatus = Status.awake(Obj1())
if case .awake = deviceStatus {
print("awake")
} else if case .sleeping = deviceStatus {
print("sleeping")
}
// you can also use a switch statement
switch deviceStatus {
case .awake:
print("awake")
case .sleeping:
print("sleeping")
default:
print("something else")
}
