在UITableView中顯示解析的JSON

Question

我有這個UITableView，我已經從webservice解析數據並加載到NSDictionary中，它的所有工作都很好，數據顯示id和imageurl到tableview中問題是logo-id，它是一個int完美展現，當我向下滾動tableview中，但是當我向上滾動的tableview它消失了，當我csroll下再次出現，並在那裏停留

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{ 
    //Where we configure the cell in each row 

    static NSString *CellIdentifier = @"Cell"; 
    UITableViewCell *cell; 

    cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    // if (cell == nil) { 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]; 
    // } 
    // Configure the cell... setting the text of our cell's label 

    NSDictionary *dic = [json objectAtIndex:[indexPath row]]; 


    NSString *strImage = [dic objectForKey:@"image-name-small"]; 
    NSURL *ImageURL = [NSURL URLWithString:[strImage stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 
    AsyncImageView *asyncImgView = [[AsyncImageView alloc] initWithFrame:CGRectMake(3, 10, 100, 100)]; 
    asyncImgView.contentMode = UIViewContentModeScaleAspectFit; 
    asyncImgView.backgroundColor = [UIColor clearColor]; 
    [asyncImgView loadImageFromURL:ImageURL]; 





    UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(200, 200, 100, 25)]; 
    lbl.text = [dic objectForKey:@"logo-id"]; 
    [cell addSubview:lbl]; 
    [cell addSubview:asyncImgView]; 
    cell.textLabel.text = @""; 
    return cell; 
}

如果電池addSubview不起作用試試這個：

[cell.contentView addSubView:lbl]; 

或嘗試默認單元格屬性：

cell.textLabel.text=@"sample text"; 

//嘗試此代碼：

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath: (NSIndexPath *)indexPath{ 

static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; 
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier]; 

if(cell == nil) 
{ 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier]; 
} 
else 
{ 
    for (UIView *subview in cell.contentView.subviews) 
     [subview removeFromSuperview]; 
} 

NSDictionary *dic = [json objectAtIndex:[indexPath row]]; 


NSString *strImage = [dic objectForKey:@"image-name-small"]; 
NSURL *ImageURL = [NSURL URLWithString:[strImage stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 
AsyncImageView *asyncImgView = [[AsyncImageView alloc] initWithFrame:CGRectMake(3, 10, 100, 100)]; 
asyncImgView.contentMode = UIViewContentModeScaleAspectFit; 
asyncImgView.backgroundColor = [UIColor clearColor]; 
[asyncImgView loadImageFromURL:ImageURL]; 

UILabel *lbl = [[UILabel alloc]initWithFrame:CGRectMake(200, 200, 100, 25)]; 
lbl.backgroundColor=[UIColor redColor]; 
lbl.text = [dic objectForKey:@"logo-id"]; 

[cell.contentView addSubview:lbl]; 
[cell.contentView addSubview:asyncImgView]; 

return cell; 

}
