swift - 比较 Swift 中的 Objective-C 枚举值

Question

我正尝试在 Swift 中这样做:

var netStatus:NetworkStatus = reachability.currentReachabilityStatus();
if (!netStatus) { // error here says network status not convertible to bool
    ....
}

typedef enum : NSInteger {
    NotReachable = 0,
    ReachableViaWiFi,
    ReachableViaWWAN
} NetworkStatus;

我也试过

if (netStatus ==0)
if (netStatus == NetworkStatus.NotReachable) // NetworkStatus.type does not have a member named 'NotReachable'

等等

尝试使用现代 Objective-C 实践:

typedef NS_ENUM(NSInteger, NetworkStatus) {
        NetworkStatusNotReachable,
        NetworkStatusReachableViaWiFi,
        NetworkStatusReachableViaWAN
};
