ios项目绕过证书访问https程序

如果是单个的webview或者request请求，在请求的文件h中直接实现NSURLConnectionDelegate，并在m中添加下列实现下列两个方法：

C代码







- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {

return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];

}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {

if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])

//if ([trustedHosts containsObject:challenge.protectionSpace.host])

[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]

forAuthenticationChallenge:challenge];

[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];

}

- (BOOL)connection:(NSURLConnection *)connection canAuthenticateAgainstProtectionSpace:(NSURLProtectionSpace *)protectionSpace {
return [protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust];
}

- (void)connection:(NSURLConnection *)connection didReceiveAuthenticationChallenge:(NSURLAuthenticationChallenge *)challenge {
if ([challenge.protectionSpace.authenticationMethod isEqualToString:NSURLAuthenticationMethodServerTrust])
//if ([trustedHosts containsObject:challenge.protectionSpace.host])
[challenge.sender useCredential:[NSURLCredential credentialForTrust:challenge.protectionSpace.serverTrust]
forAuthenticationChallenge:challenge];
[challenge.sender continueWithoutCredentialForAuthenticationChallenge:challenge];
}

上述方法很不爽的是每个请求的地方都要加。

如果项目中用到了three20，直接修改“TTRequestLoader.m”即可，这个文件本身就已经实现了NSURLConnectionDelegate，

修改如下，只改这一个地方就行，处处可用。
