好吧,所以我知道有關於此的網上文檔噸,我覺得我已經嘗試了一切,仍然無法讓它工作。我正在嘗試使用我在IB中創建的自定義單元來實現tableview。文件的CustomCell.xib
文件的所有者是UITableViewCell
。這是我在實現表視圖頭文件:iphone uitableview與自定義單元格 - xcode 4
#import <UIKit/UIKit.h>
@interface QuickCalcController : UIViewController<UITabBarDelegate, UITableViewDelegate, UITableViewDataSource>{
NSMutableArray *numbers;
NSMutableArray *discount_numbers;
}
@property (nonatomic, retain) IBOutlet UITableView *tblView;
@end
,這裏是在執行文件中的代碼:
- (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;
}
我已經在自定義單元格連接標籤到standardLabel
和discountLabel
於DiscountCellController
。我得到這個錯誤:
[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.'
因爲我錯過了什麼?
我想你需要投DiscountCellController * cell =(DiscountCellController *)[ tblView ... for one thing。另外,你可以分享DiscountCellController的代碼嗎? – Jim
