在iphone应用程序中的表格

Question

我正在制作一个iPhone应用程序，它需要我使用网站表单来获取数据库中的值，并且可以通过我的iPhone应用程序以JSON格式进行查询。

现在我想，因为我的网站形式只有5-6个字段填满，我可以在我的iphone应用程序本身做一个表单吗？然后，我可以将这些表单数据以JSON格式发送到网络服务器。 有人请指导我。

您可以通过post方法将数据发送给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]; 
} 

}
