对App进行实时的网络状态监听也是项目中的一项比较重要的功能.
在写项目的时候也查阅了很多资料,基本就两种方法:Reachability和AFNetworking两种方法.
这两种方法的具体实现方法在简书上都有很多很不错的文章讲过
但这篇文章我想讲讲查到的另一个判断网络类型的方法---通过状态栏判断网络类型
我的项目内采用的是AFNetworkReachabilityManager,它的底层代码就是对系统的Reachability的二次封装,使用起来能更方便些.话不多说了,看一下具体的实现
[[AFNetworkReachabilityManager sharedManager] setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {
switch (status)
{
//结合MBProgressHUD进行显示:
case -1: //AFNetworkReachabilityStatusUnknown
{
//提示框:
MBProgressHUD *textOnlyHUD = [MBProgressHUD showHUDAddedTo:self.tabBarController.view animated:YES];
textOnlyHUD.mode = MBProgressHUDModeText;
textOnlyHUD.labelText = @"未知网络";
[textOnlyHUD hide:YES afterDelay:1.f];
}
break;
case 0: //AFNetworkReachabilityStatusNotReachable
{
//提示框:
MBProgressHUD *textOnlyHUD = [MBProgressHUD showHUDAddedTo:self.tabBarController.view animated:YES];
textOnlyHUD.mode = MBProgressHUDModeText;
textOnlyHUD.labelText = @"无法连接";
[textOnlyHUD hide:YES afterDelay:1.f];
}
break;
case 1: //AFNetworkReachabilityStatusReachableViaWWAN
{
//这里是本文的核心点:采用遍历查找状态栏的显示网络状态的子视图,通过判断该子视图的类型来更详细的判断网络类型
NSArray *subviewArray = [[[[UIApplication sharedApplication] valueForKeyPath:@"statusBar"] valueForKeyPath:@"foregroundView"] subviews];
int type = 0;
for (id subview in subviewArray)
{
if ([subview isKindOfClass:NSClassFromString(@"UIStatusBarDataNetworkItemView")])
{
type = [[subview valueForKeyPath:@"dataNetworkType"] intValue];
}
switch (type)
{
case 1:
{
//提示框:
MBProgressHUD *textOnlyHUD = [MBProgressHUD showHUDAddedTo:self.tabBarController.view animated:YES];
textOnlyHUD.mode = MBProgressHUDModeText;
textOnlyHUD.labelText = @"当前为2G网络";
[textOnlyHUD hide:YES afterDelay:1.f];
}
break;
case 2:
{
//提示框:
MBProgressHUD *textOnlyHUD = [MBProgressHUD showHUDAddedTo:self.tabBarController.view animated:YES];
textOnlyHUD.mode = MBProgressHUDModeText;
textOnlyHUD.labelText = @"当前为3G网络";
[textOnlyHUD hide:YES afterDelay:1.f];
}
break;
case 3:
{
//提示框:
MBProgressHUD *textOnlyHUD = [MBProgressHUD showHUDAddedTo:self.tabBarController.view animated:YES];
textOnlyHUD.mode = MBProgressHUDModeText;
textOnlyHUD.labelText = @"当前为4G网络";
[textOnlyHUD hide:YES afterDelay:1.f];
}
break;
default:
break;
}
}
}
break;
case 2: //AFNetworkReachabilityStatusReachableViaWiFi
{
//提示框:
MBProgressHUD *textOnlyHUD = [MBProgressHUD showHUDAddedTo:self.tabBarController.view animated:YES];
textOnlyHUD.mode = MBProgressHUDModeText;
textOnlyHUD.labelText = @"当前为WIFI";
[textOnlyHUD hide:YES afterDelay:1.f];
}
break;
default:
{
//提示框:
MBProgressHUD *textOnlyHUD = [MBProgressHUD showHUDAddedTo:self.tabBarController.view animated:YES];
textOnlyHUD.mode = MBProgressHUDModeText;
textOnlyHUD.labelText = @"无网络连接";
[textOnlyHUD hide:YES afterDelay:1.f];
}
break;
}
}];
//开始监测
[[AFNetworkReachabilityManager sharedManager] startMonitoring];
最后的实现效果:
WIFI
3G
此方法最大的好处就是能够更详细的监听网络类型,能够和用户的视觉信息一致,会有更好的用户体验.(个人感觉)希望能够给大家一点收获,我觉得拓宽思路,这种方法还能有更高的使用价值
