項(xiàng)目中經(jīng)常會(huì)遇到需要獲取當(dāng)前的網(wǎng)絡(luò)狀態(tài)，自己就簡單的封裝了一下。

• 基于AFNetworking的網(wǎng)絡(luò)監(jiān)測

1.import "NetworkStatus.h"

#import <Foundation/Foundation.h>
#import "AFNetworking.h"

typedef void(^netStateBlock)(NSInteger netState);

@interface NetworkStatus : NSObject

+ (instancetype)sharedNetManager;

/**
 *  網(wǎng)絡(luò)監(jiān)測
 *  @param block 判斷結(jié)果回調(diào)
 *  @return 網(wǎng)絡(luò)監(jiān)測
 */
+ (void)netWorkState:(netStateBlock)block;

@end

2.import "NetworkStatus.m"

#pragma mark - 網(wǎng)絡(luò)監(jiān)測
+ (instancetype)sharedNetManager {
    static dispatch_once_t once;
    static NetworkStatus *sharedInstance;
    dispatch_once(&once, ^{
        sharedInstance = [[self alloc] init];
    });
    return sharedInstance;
}

#pragma mark----網(wǎng)絡(luò)檢測
+ (void)netWorkState:(netStateBlock)block {
    
    AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];
    [manager startMonitoring];
    [manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
        if (status== 0 || status == -1) {
            block(status);
        }else{
            block(status);
        }
    }];
}

3.調(diào)用

[NetworkStatus netWorkState:^(NSInteger netState) {
        
        switch (netState) {
            case 1:{
                NSLog(@"手機(jī)流量上網(wǎng)");
            }
                break;
            case 2:{
                NSLog(@"WIFI上網(wǎng)");
            }
                break;
            default:{
                NSLog(@"沒網(wǎng)");
            }
                break;
        }
    }];

4.網(wǎng)絡(luò)狀態(tài)

 AFNetworkReachabilityStatusUnknown          = -1,  //未知的網(wǎng)絡(luò)
 AFNetworkReachabilityStatusNotReachable     = 0,   // 無連接
 AFNetworkReachabilityStatusReachableViaWWAN = 1,   //2G,3G,4G
 AFNetworkReachabilityStatusReachableViaWiFi = 2,   //wifi網(wǎng)絡(luò)
