我使用IB和Storyboards在UITableView中創建了自定義單元格。下面的代碼是加載該自定義單元的代碼;問題是雖然cA.cBusName和cA.cOrderDate中有有效的數據,但cell標籤(cell.busNameLabel.text,cell.orderDateLagbel.text)沒有設置。 問題是:爲什麼這不起作用?爲什麼UITableCell不顯示內容
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"CustomerListingsCell";
CustomerListingsCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[CustomerListingsCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
// Configure the cell...
SingletonListOfCustomers *shareInstance = [SingletonListOfCustomers sharedInstance];
cArray *cA = [shareInstance.listOfCustomers objectAtIndex: indexPath.row];
cell.busNameLabel.text = cA.cBusName;
cell.orderDateLabel.text = cA.cOrderDate;
NSLog(@"\n\nindexPath.row: %d, busNameLabel: %@, orderDateLabel: %@", indexPath.row, cA.cBusName, cA.cOrderDate);
NSLog(@"\nindexPath.row: %d, cell.busNameLabel: %@, cell.orderDateLabel: %@", indexPath.row, cell.busNameLabel.text, cell.orderDateLabel.text);
return cell;
}
CustomerListingsCell定義爲:
@interface CustomerListingsCell : UITableViewCell {
}
@property (nonatomic, strong) IBOutlet UILabel *busNameLabel;
@property (nonatomic, strong) IBOutlet UILabel *orderDateLabel;
@end
的的NSLog語句輸出是:
2012-05-24 14:01:55.363空白麪料[4876:F803]
indexPath.row:0,busNameLabel:隱藏的針跡,orderDateLabel: 2012-05-24 2012-05-24 14:01:5 5.364空白麪料[4876:f803] indexPath.row:0,cell.busNameLabel:(null),cell.orderDateLabel: (null)2012-05-24 14:01:55.365 Blank Fabrics [4876:f803]
indexPath.row:1,busNameLabel:Prager,Software,orderDateLabel: 05/24/2012 2012-05-24 14:01:55.373 Blank Fabrics [4876:f803] indexPath.row:1,cell.busNameLabel: (null),cell.orderDateLabel: (null)
你能舉一個2個NSLog語句打印的例子嗎? (也許只是'NSLog(@「Cell:%@」,cell);'? –
根據請求更新NSLog語句... – SpokaneDude
嘗試使用cell.textLabel.text = cA.cBusName;如果它工作,那麼你的自定義tableviewcell上的連接是錯誤的。 – 3lvis
