WebView怎么加载post请求并且传参数？

UIWebView *webView = [[UIWebView alloc] init];

NSString *bodyShare = [NSString stringWithFormat: @"hID:%@", userID];

NSMutableURLRequest * requestShare = [[NSMutableURLRequest alloc]initWithURL:[NSURL URLWithString:self.urlStr]];

[requestShare setHTTPMethod: @"POST"];

[requestShare setHTTPBody: [bodyShare dataUsingEncoding: NSUTF8StringEncoding]];

[webView loadRequest:requestShare];
