iphone - iphone 应用程序中的表单

Question

我正在制作一个 iPhone 应用程序，它要求我使用网站表单将值输入数据库，并且我可以通过我的 iPhone 应用程序以 JSON 形式查询。

现在我在想，由于我的网站表单只有 5-6 个字段需要填写，我可以在我的 iPhone 应用程序中自己制作一个表单吗？然后我可以将该表单数据以 JSON 格式发送到网络服务器。有人请指导我。

可以通过post方式将数据发送给jason。

-(void)registration:(NSString *)nickName 
  TeamName:(NSString *)teamName
  Age:(NSString *)age
  Nationality:(NSString *)countryName

{   
NSString *JSON = [NSString stringWithFormat:@"{\"NICKNAME\":\"%@\"",nickName];
JSON = [JSON stringByAppendingFormat:@",\"TEAM_NAME\":\"%@\"",teamName];
JSON = [JSON stringByAppendingFormat:@",\"AGE\":\"%@\"",age];
JSON = [JSON stringByAppendingFormat:@",\"NATIONALITY\":\"%@\"",countryName];
NSLog(@"%@", JSON);

  NSData *postData = [JSON dataUsingEncoding:NSUTF8StringEncoding allowLossyConversion:YES];    
  NSString *strURL = [NSString stringWithFormat:@"%@%@", kServerPath, kUserRegisterPath];

NSLog(@"Resgistration URL: %@", strURL);

NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:strURL] cachePolicy:NSURLRequestReloadIgnoringLocalCacheData timeoutInterval:120.0];    

[request setHTTPMethod:@"POST"];
[request setValue:@"application/json" forHTTPHeaderField:@"Content-Type"];
[request setValue:@"application/json" forHTTPHeaderField:@"Accept"];

[request setHTTPBody:postData];

NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:request delegate:[WebServices sharedInstance]];


if(theConnection) {
    NSLog(@"connection made");
}

else {
    NSLog(@"theConnection is NULL");

    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Error " message:@"Network not responding"  delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
    [alert show];
}

}
