需要用到第三方AFNetworking/SVProgressHUD
没有的可以关注我微博私信我.http://weibo.com/hanjunqiang
AppDelegate.m
#import "AFNetworking.h" #import "SVProgressHUD.h"代码实现比较简单:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { // Override point for customization after application launch. [SVProgressHUD setDefaultMaskType:SVProgressHUDMaskTypeNone]; [SVProgressHUD setRingThickness:8]; // 1. 获得网络监控的管理者 AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager]; // 2. 设置网络状态改变后的处理 [manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) { // 当网络状态改变了, 就会调用这个block switch (status) { case AFNetworkReachabilityStatusUnknown: NSLog(@"未知网络"); break; case AFNetworkReachabilityStatusNotReachable: NSLog(@"没有网络(断网)"); break; case AFNetworkReachabilityStatusReachableViaWWAN: NSLog(@"手机自带网络"); break; case AFNetworkReachabilityStatusReachableViaWiFi: NSLog(@"WIFI"); [SVProgressHUD showSuccessWithStatus:@"WIFI"]; break; } }]; // 3. 开始监控 [manager startMonitoring]; return YES; }
最终效果:
