好吧,所以我知道有关于此的网上文档吨,我觉得我已经尝试了一切,仍然无法让它工作。我正在尝试使用我在IB中创建的自定义单元来实现tableview。文件的CustomCell.xib
文件的所有者是UITableViewCell
。这是我在实现表视图头文件:iphone uitableview与自定义单元格 - xcode 4
#import <UIKit/UIKit.h>
@interface QuickCalcController : UIViewController<UITabBarDelegate, UITableViewDelegate, UITableViewDataSource>{
NSMutableArray *numbers;
NSMutableArray *discount_numbers;
}
@property (nonatomic, retain) IBOutlet UITableView *tblView;
@end
,这里是在执行文件中的代码:
- (UITableViewCell *)tableView:(UITableView *)tblView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = @"DiscountCellController";
DiscountCellController *cell = [tblView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil){
NSLog(@"New Cell Made");
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"DiscountCellController" owner:nil options:nil];
for(id currentObject in topLevelObjects)
{
if([currentObject isKindOfClass:[DiscountCellController class]])
{
cell = (DiscountCellController *)currentObject;
break;
}
}
}
cell.standardLabel.text = @"hi";//[discount_numbers objectAtIndex:indexPath.row];
cell.discountLabel.text = @"hi";//[discount_numbers objectAtIndex:indexPath.row];
NSLog(@"setting the cell");
return cell;
}
#pragma mark -
#pragma mark Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tblView
{
return 1;
}
- (NSString *)tableView:(UITableView *)tblView titleForHeaderInSection: (NSInteger)section
{
return nil;
}
- (NSInteger)tableView:(UITableView *)tblView numberOfRowsInSection:(NSInteger)section
{
return 5;
}
- (NSArray *)sectionIndexTitlesForTableView:(UITableView *)tblView {
return nil;
}
我已经在自定义单元格连接标签到standardLabel
和discountLabel
于DiscountCellController
。我得到这个错误:
[3390:207] *** Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[<NSObject 0x4e227d0> setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key standardLabel.'
因为我错过了什么?
我想你需要投DiscountCellController * cell =(DiscountCellController *)[ tblView ... for one thing。另外,你可以分享DiscountCellController的代码吗? – Jim
