项目中经常会遇到需要获取当前的网络状态，自己就简单的封装了一下。
- 基于AFNetworking的网络监测
1.import "NetworkStatus.h"
#import <Foundation/Foundation.h>
#import "AFNetworking.h"
typedef void(^netStateBlock)(NSInteger netState);
@interface NetworkStatus : NSObject
+ (instancetype)sharedNetManager;
/**
* 网络监测
* @param block 判断结果回调
* @return 网络监测
*/
+ (void)netWorkState:(netStateBlock)block;
@end
2.import "NetworkStatus.m"
#pragma mark - 网络监测
+ (instancetype)sharedNetManager {
static dispatch_once_t once;
static NetworkStatus *sharedInstance;
dispatch_once(&once, ^{
sharedInstance = [[self alloc] init];
});
return sharedInstance;
}
#pragma mark----网络检测
+ (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.调用
[NetworkStatus netWorkState:^(NSInteger netState) {
switch (netState) {
case 1:{
NSLog(@"手机流量上网");
}
break;
case 2:{
NSLog(@"WIFI上网");
}
break;
default:{
NSLog(@"没网");
}
break;
}
}];
4.网络状态
AFNetworkReachabilityStatusUnknown = -1, //未知的网络
AFNetworkReachabilityStatusNotReachable = 0, // 无连接
AFNetworkReachabilityStatusReachableViaWWAN = 1, //2G,3G,4G
AFNetworkReachabilityStatusReachableViaWiFi = 2, //wifi网络
