检測网络连接状态

非常久后:
- (NetworkStatus)statusForNet
{
Reachability *reachability = [Reachability reachabilityWithHostName:@"www.apple.com"];
NetworkStatus netStatus = [reachability currentReachabilityStatus];
return netStatus;
}
- (BOOL)isHaveNetWork
{
if([self statusForNet] == ReachableViaWiFi || [self statusForNet] == ReachableViaWWAN){
return YES;
}else{
return NO;
}
}
- (void)replyAction:(UIButton *)sender
{
if ([self isHaveNetWork]){
//
}else{
[self showTextPrompt:nil
prompt:@"当前没有网络"];
sender.userInteractionEnabled = NO;
}
sender.userInteractionEnabled = YES;
}
说说为什么这个时候贴出这些代码, 关于项目的严谨性,断网的时候须要做一些预判的,我们常规的返回结果都是请求后给的,达不到想要的效果,比方没网时关闭用户交互并提示
