非常久後:
- (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:@"當前沒有網絡"];
sender.userInteractionEnabled = NO;
}
sender.userInteractionEnabled = YES;
}
說說為什麽這個時候貼出這些代碼, 關於項目的嚴謹性,斷網的時候須要做一些預判的,我們常規的返回結果都是請求後給的,達不到想要的效果,比方沒網時關閉用戶交互並提示
