[request setHTTPMethod: @"POST"]; 
[request setHTTPBody: [body dataUsingEncoding: NSUTF8StringEncoding]]; 
[_webView loadRequest: request]; 

Answer 1

你已经错过了格式说明尝试使用此

NSString *body = [NSString stringWithFormat: @"txtemail=%@&txtpwd=%@&txtcpwd=%@", email, password,confirmpassword]; 

Answer 2

您的格式字符串只有2个格式说明符，但您传递的是3个参数。让他们匹配。

检查：

[NSString stringWithFormat: @"txtemail=%@&txtpwd=%@&txtcpwd=%@", email, password,confirmpassword]; 

Answer 3

试用确认passord这个..你已经错过了格式说明(%@)。

NSString *body = [NSString stringWithFormat: @"txtemail=%@&txtpwd=%@&txtcpwd=%@", email, password,confirmpassword]; 

更新：尝试网址与http://

NSURL *url = [NSURL URLWithString: @"http://www.bikrionline.com/database/iqry_mbr_mst.php"]; 

入住这也..

UIWebView *webView=[[UIWebView alloc] initWithFrame:CGRectMake(0,0,320,480); 
[self.view addSubView:webView];
