Question

<分区>

Answer 1

对于定位服务你可以检查

[CLLocationManager locationServicesEnabled]

返回 BOOL 值

对于互联网可达性，您可以使用苹果提供的可达性类 http://developer.apple.com/library/ios/#samplecode/Reachability/Introduction/Intro.html

像这样使用代码

Reachability *networkReachability = [Reachability reachabilityForInternetConnection];   
NetworkStatus networkStatus = [networkReachability currentReachabilityStatus];    
if (networkStatus == NotReachable) {        
    NSLog(@"There IS NO internet connection");        
} else {        
    NSLog(@"There IS internet connection");        
    }        
}
