ios - 如何在 objective-c 中将 SOAP 数据发布到服务器

我正在尝试将数据发布到服务器，但它给了我错误 代码是

-(IBAction)loginBtnClkid)sender
{
  [self sendDataToServer "OST"];
}

-(void) sendDataToServer : (NSString *) method{

    int UserId=0;

    NSData *postData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

    NSString *postLength = [NSString stringWithFormat"%lu",(unsigned long)[post length]];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];

        NSLog(@"Connection Successful");
    } else {

它终于运行了。只是我改了代码

-(IBAction)sendDataUsingGet:(id)sender{

    [self sendDataToServer : @"GET"];
}
-(void) sendDataToServer : (NSString *) method{

    int UserId=idtxt.text;
    NSString *UserCode  = userTf.text;
