讀取iOS代理設定的代碼

轉自: http://www.cocoachina.com/iphonedev/toolthain/2011/1118/3538.html

用過ASIHTTPRequest這個開源網路程式庫，它可以讀取代理設定，於是我在源碼中發現讀取代理設定的方法，我已把代碼提取出來：

 

NSDictionary *proxySettings = NSMakeCollectable([(NSDictionary *)CFNetworkCopySystemProxySettings() autorelease]); 
NSArray *proxies = NSMakeCollectable([(NSArray *)CFNetworkCopyProxiesForURL((CFURLRef)[NSURL URLWithString:@"http://www.google.com"], (CFDictionaryRef)proxySettings) autorelease]); 
NSDictionary *settings = [proxies objectAtIndex:0]; 
NSLog(@"host=%@", [settings objectForKey:(NSString *)kCFProxyHostNameKey]); 
NSLog(@"port=%@", [settings objectForKey:(NSString *)kCFProxyPortNumberKey]); 
NSLog(@"type=%@", [settings objectForKey:(NSString *)kCFProxyTypeKey]);

 

需要CFNetwork.framework
