UIWebView帶Post請求地址

UIWebView帶Post請求地址，如果使用Get方式的話，請求的參數直接拼接在Url裏面就好。如果是Post方式就需要放在Body裏面

    NSURL *url = [NSURL URLWithString: @"www.baidu.com"];

    NSString *body = [NSString stringWithFormat: @"arg1=%@&arg2=%@", @"val1",@"val2"];

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc]initWithURL: url];
    [request setHTTPMethod: @"POST"];
    [request setHTTPBody: [body dataUsingEncoding: NSUTF8StringEncoding]];
    [self.webView loadRequest: request];
