Question

iOS开发 之 检测是否有网络连接

Answer 1

要引入AFNetworkReachabilityManager
AFNetworkReachabilityManager *networkJudge = [AFNetworkReachabilityManager sharedManager];

[networkJudge startMonitoring];

[networkJudge setReachabilityStatusChangeBlock:^(AFNetworkReachabilityStatus status) {

if (status == AFNetworkReachabilityStatusNotReachable && [YShareModel shareInstance].remindNetwork) {

alert = [[UIAlertView alloc] initWithTitle:@"通知" message:@"网络连接已断开" delegate:self cancelButtonTitle:@"OK" otherButtonTitles: nil];

[alert show];

}else if (status != AFNetworkReachabilityStatusNotReachable) {

[alert dismissWithClickedButtonIndex:0 animated:YES];

}

}];
