可达性块应用

发布于 2024-12-17 11:27:10 字数 722 浏览 5 评论 0原文

在我的应用程序中的 appDelegate .mi 中插入了像苹果所说的可达性代码：

-(BOOL)checkInternet
{
Reachability *r = [Reachability reachabilityWithHostName:@"google.com"];
NetworkStatus internetStatus = [r currentReachabilityStatus];
BOOL internet;
if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN)) {
    internet = NO;
} else {
    internet = YES;
}
return internet;
}

并在我的 viewcontroller.m 中的方法中 - (void)applicationDidBecomeActive:(UIApplication *)application {

gotInternet = [self checkInternet];
if ( gotInternet == 0)
{
//No connection
} else {
//Connection ok
}

但是当网络 3g 出现问题时我的应用程序之后大约 20 秒，由于延迟太大，它崩溃了。如何异步实现控制连接，而不带看门狗？

谢谢

in my app in the appDelegate .m i have insert the reachability code like apple say:

-(BOOL)checkInternet
{
Reachability *r = [Reachability reachabilityWithHostName:@"google.com"];
NetworkStatus internetStatus = [r currentReachabilityStatus];
BOOL internet;
if ((internetStatus != ReachableViaWiFi) && (internetStatus != ReachableViaWWAN)) {
    internet = NO;
} else {
    internet = YES;
}
return internet;
}

and in my viewcontroller.m in the method - (void)applicationDidBecomeActive:(UIApplication *)application {

gotInternet = [self checkInternet];
if ( gotInternet == 0)
{
//No connection
} else {
//Connection ok
}

but when there are problems on the network 3g my application after about 20 seconds it crashes because of too much latency. How do I implement the control connection asynchronously, never to take the watchdog?

thanks
