、削除ボタンを押すと、それはWebServerのデータソースから選択されたオブジェクトを削除すると

Question

ファイルNSObjectのからのUITableViewデータを再ロードすることができませんが、テーブルビューを再ロードすることができない、

ここでは私のコードで、これを達成するためにどのようにすることをアドバイスしてください私がこれを間違ってやっているところを 私に知らせるようにしてください。

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"myCell" forIndexPath:indexPath]; 

    Records * RecordsObject; 

    RecordsObject = [recordsArray objectAtIndex:indexPath.row]; 
    cell.textLabel.text = RecordsObject.recordsMname; 
    cell.detailTextLabel.text= RecordsObject.recordsImei; 

    UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [detailButton setImage:[UIImage imageNamed:@"edit"] forState:UIControlStateNormal]; 
    detailButton.frame = CGRectMake(WidthCalculation - 45, 0.0f, 50.0f, 45.0f); 
    [cell addSubview:detailButton]; 
    [detailButton addTarget:self 
        action:@selector(detailsButton:) 
      forControlEvents:UIControlEventTouchUpInside]; 
    [cell.contentView addSubview:detailButton]; 
    [detailButton setTag:indexPath.row]; 


    UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [deleteButton setImage:[UIImage imageNamed:@"trash"] forState:UIControlStateNormal]; 
    deleteButton.frame = CGRectMake(WidthCalculation - 75, 0.0f, 50.0f, 45.0f); 
    [cell addSubview:deleteButton]; 
    [deleteButton addTarget:self 
         action:@selector(delButton:event:) 
      forControlEvents:UIControlEventTouchUpInside]; 
    [cell.contentView addSubview:deleteButton]; 



    // Configure the cell... 

    return cell; 
} 

削除ボタン機能

- (IBAction)delButton: (UIButton*)button event:(UIEvent*)event 
{ 
    UIButton *delButton = button; 
    NSLog(@"FaceBook Button is sharing %li row's Image", (long)delButton.tag); 

    NSIndexPath* indexPath = [self.tableView indexPathForRowAtPoint: 
           [[[event touchesForView:button] anyObject] 
           locationInView:self.tableView]]; 

    Records *object = self.recordsArray[delButton.tag]; 
    NSLog(@"selected Object %@", object); 
    NSString *id = object.recordsId; 
    NSMutableString * postString = [NSMutableString stringWithString:kdeleteURL]; 
    [postString appendString:[NSString stringWithFormat:@"?%@=%@", kId, id]]; 
    [postString setString:[postString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]]]; 

    NSMutableURLRequest *request =[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:postString]]; 

    [request setHTTPMethod:@"POST"]; 

    postConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES]; 
    [self.recordsArray removeObjectAtIndex:indexPath.row]; 

      [self.tableView reloadData]; 


} 

あなたは、このようなオブジェクトファイルまたはサーバー側からデータを取得するためのデータ検索コードスニペットのコードのようになりより多くの情報が必要な場合は私に知らせてください。

Answer 1

NSIndexPath *index = [[NSIndexPath alloc] init]; 

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"myCell" forIndexPath:indexPath]; 

    Records * RecordsObject; 

    RecordsObject = [recordsArray objectAtIndex:indexPath.row]; 
    cell.textLabel.text = RecordsObject.recordsMname; 
    cell.detailTextLabel.text= RecordsObject.recordsImei; 

    UIButton *detailButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [detailButton setImage:[UIImage imageNamed:@"edit"] forState:UIControlStateNormal]; 
    detailButton.frame = CGRectMake(WidthCalculation - 45, 0.0f, 50.0f, 45.0f); 
    [cell addSubview:detailButton]; 
    [detailButton addTarget:self 
        action:@selector(detailsButton:) 
      forControlEvents:UIControlEventTouchUpInside]; 
    [cell.contentView addSubview:detailButton]; 
    [detailButton setTag:indexPath.row]; 


    UIButton *deleteButton = [UIButton buttonWithType:UIButtonTypeCustom]; 
    [deleteButton setImage:[UIImage imageNamed:@"trash"] forState:UIControlStateNormal]; 
    deleteButton.frame = CGRectMake(WidthCalculation - 75, 0.0f, 50.0f, 45.0f); 
    deleteButton.tag = indexPath.row 
    [cell addSubview:deleteButton]; 
    [deleteButton addTarget:self 
         action:@selector(delButton:event:) 
      forControlEvents:UIControlEventTouchUpInside]; 
    [cell.contentView addSubview:deleteButton]; 



    // Configure the cell... 

    return cell; 
} 

- (IBAction)delButton: (UIButton*)button event:(UIEvent*)event 
{ 
    UIButton *delButton = button; 
    NSLog(@"FaceBook Button is sharing %li row's Image", (long)delButton.tag); 

    NSIndexPath* indexPath = [self.tableView indexPathForRowAtPoint: 
           [[[event touchesForView:button] anyObject] 
           locationInView:self.tableView]]; 

    Records *object = self.recordsArray[delButton.tag]; 
    NSLog(@"selected Object %@", object); 
    NSString *id = object.recordsId; 
    NSMutableString * postString = [NSMutableString stringWithString:kdeleteURL]; 
    [postString appendString:[NSString stringWithFormat:@"?%@=%@", kId, id]]; 
    [postString setString:[postString stringByAddingPercentEncodingWithAllowedCharacters:[NSCharacterSet URLFragmentAllowedCharacterSet]]]; 

    NSMutableURLRequest *request =[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:postString]]; 

    [request setHTTPMethod:@"POST"]; 

    postConnection = [[NSURLConnection alloc] initWithRequest:request delegate:self startImmediately:YES]; 
    index = indexPath 
} 

成功したら、配列から行とオブジェクトを削除します。

-(void)serviceResponce() { 
    [self.recordsArray removeObjectAtIndex:indexPath.row]; 
    [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject: index] withRowAnimation:UITableViewRowAnimationNone]; 
}
