NSURLConnection NSMutableURLRequest和HTTPS

Question

我有以下上传图像到网站的代码。

[request setURL:nsurl];
[request setHTTPMethod:@"POST"];  

NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];  
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];  
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];  

/* 
 now lets create the body of the post 
 */  
NSMutableData *body = [NSMutableData data];  

//parameter1  
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];   
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"guid\"\r\n\r\n%@", [Settings sharedInstance].uploadID] dataUsingEncoding:NSUTF8StringEncoding]];  
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];  
//Image  
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"filMyFile\"; filename=\"%@\"\r\n", fileName] dataUsingEncoding:NSUTF8StringEncoding]];  
[body appendData:[[NSString stringWithString:@"Content-Type: image/png\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];  
[body appendData:[NSData dataWithData:dataObj]];  
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];  

// setting the body of the post to the reqeust  
[request setHTTPBody:body];  

NSURLConnection *connection = [[NSURLConnection alloc] initWithRequest:request delegate:self];

在HTTP上运行时，一切都很好，但当我切换到HTTPS时，它会失败，如下所示

错误:错误Domain=NSURLErrorDomain代码=-1005“网络连接丢失。”UserInfo=0x1c7f70 {NSErrorFailingURLStringKey=https:.......

它与之通信的服务器是MS Server2008 R2。

任何想法都将不胜感激。
