Can any one get me idea to find whether iphone device connected to 3G /Wifi using Reachability.kindly get me some samples / URL's .im new in this iphone development.
Thanks in advance
您可以尝试从Apple http://developer.apple.com/iphone/library/samplecode/Reachability/的Rechability示例开始
firstly add SystemConfiguration.framework to your project
//Class.h
#import "Reachability.h"
#import <SystemConfiguration/SystemConfiguration.h>
- (BOOL)connected;
//Class.m
- (BOOL)connected
{
Reachability *reachability = [Reachability reachabilityForInternetConnection];
NetworkStatus networkStatus = [reachability currentReachabilityStatus];
return networkStatus != NotReachable;
}
Then, I use this whenever I want to see if I have a connection:
if (![self connected]) {
// Not connected
} else {
// Connected. Do some Internet stuff
}
