iphone - 检测无线网络名称

Question

是否可以运行一个方法来返回用户所连接的无线网络的名称？在我的应用程序内部，我希望能够返回用户连接到的无线网络的名称。

这对我来说非常有效:

#import <SystemConfiguration/CaptiveNetwork.h>

CFArrayRef myArray = CNCopySupportedInterfaces();
CFDictionaryRef myDict = CNCopyCurrentNetworkInfo(CFArrayGetValueAtIndex(myArray, 0));
//    NSLog(@"SSID: %@",CFDictionaryGetValue(myDict, kCNNetworkInfoKeySSID));
NSString *networkName = CFDictionaryGetValue(myDict, kCNNetworkInfoKeySSID);

if ([networkName isEqualToString:@"Hot Dog"])
{
    self.storeNameController = [[StoreDataController alloc] init];
    [self.storeNameController addStoreNamesObject];
}
else {
    UIAlertView *alert = [[UIAlertView alloc]initWithTitle: @"Connection Failed"
                                                   message: @"Please connect to the Hot Dog network and try again"
                                                  delegate: self
                                         cancelButtonTitle: @"Close"
                                         otherButtonTitles: nil];

    [alert show];
