只要網絡狀態(tài)發(fā)生了變化，在任何一個視圖控制器都會給出相應的提示
說明： 這里需要導入第三方庫暗膜，1. MBProgressHUD 2. AFNetworking
導入頭文件 MBProgressHUD.h, AFNetworking.h
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 應用程序加載完成
UIWindow *window = ((AppDelegate *) [UIApplication sharedApplication].delegate).window;
AFNetworkReachabilityManager *manager = [AFNetworkReachabilityManager sharedManager];
[manager setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
// 使用MBProgressHUD三方庫創(chuàng)建彈框学搜，給出相應的提示
MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:window animated:YES];
hud.mode = MBProgressHUDModeText;
switch (status) {
case AFNetworkReachabilityStatusNotReachable:
// 彈框提示的內容
hud.labelText = @"世界上最遙遠的距離就是沒網";
break;
case AFNetworkReachabilityStatusReachableViaWWAN:
hud.labelText = @"2G/3G/4G";
break;
case AFNetworkReachabilityStatusReachableViaWiFi:
hud.labelText = @"WiFi在線";
default:
break;
}
dispatch_async(dispatch_get_global_queue(0, 0), ^{
// 顯示時間2s
sleep(2);
dispatch_async(dispatch_get_main_queue(), ^{
// 讓彈框消失
[MBProgressHUD hideHUDForView:window animated:YES];
});
});
}];
[manager startMonitoring];
return YES;
}
