代码：

#import <Foundation/Foundation.h>

typedef NS_ENUM(NSUInteger, NetworkStatus){
    NetworkStatusGood = 0,
    NetworkStatusBad
};

NSString * const NetworkStatusNameMapping[] = {
    [NetworkStatusGood] = @"NetworkStatusGood",
    [NetworkStatusBad] = @"NetworkStatusBad"
};

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        // 打印枚举值与其对应的字符串
        NSLog(@"NetworkStatusGood = (%tu, %@)", NetworkStatusGood, NetworkStatusNameMapping[NetworkStatusGood]);
        NSLog(@"NetworkStatusBad = (%tu, %@)", NetworkStatusBad, NetworkStatusNameMapping[NetworkStatusBad]);
    }
    return 0;
}

输出：

NetworkStatusGood = (0, NetworkStatusGood)
NetworkStatusBad = (1, NetworkStatusBad)
