额，最近公司的接口让人给通过抓包给破解了，搞不清楚https的证书是怎么泄露的，然后就有了这么个需求，只要是网络设置了代理，那么就禁止一切网络访问，这里记录一下如何判断是否设置了代理。
需要导入框架CFNetwork
然后，这个方法是mrc的：需要添加-fno-objc-arc的flag
代码如下：
+ (BOOL)getProxyStatus {
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]);
if ([[settings objectForKey:(NSString *)kCFProxyTypeKey] isEqualToString:@"kCFProxyTypeNone"])
{
//没有设置代理
return NO;
}
else
{
//设置代理了
return YES;
}
}
