When the network connectivity is down, the data loading from internet makes my app to be in a slow state. Is there any way to fix this problem.

Answer 1

You can check for internet wherever its convenient, it can be in the viewDidLoad or didFinishLaunching methods
below is the example code i use to check for internet connection

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

Apple provide the Reachability sample application to show how you can test for network availability .. with the below code you can accomplish auto reachability

if ([[Reachability reachabilityForLocalWiFi] currentReachabilityStatus] == ReachableViaWiFi)
{
    // perform action that requires a local WiFi connection
}
else
{
    // give a message that local WiFi is required
}
