我有一个 tableView 应该填充一个NSMutableArray. 这在没有自定义原型的情况下工作得很好UITableViewCell。我有一个自己的单元格文件，名为SimpleTableCell. 我的故事板中的原型单元有这个类分配给它。SimpleTableCell.h的内容
：
#import <UIKit/UIKit.h>
@interface SimpleTableCell : UITableViewCell
@property (nonatomic, weak) IBOutlet UILabel *nameLabel;
@property (nonatomic, weak) IBOutlet UILabel *moreInfoLabel;
@end
这被导入到viewController我拥有的位置tableView，如下所示：
CargoViewController.h
#import <UIKit/UIKit.h>
#import "StartupViewController.h"
#import "boatInfoViewController.h"
#import "SimpleTableCell.h"
@interface CargoViewController : UIViewController <UIPickerViewDataSource, UIPickerViewDelegate, UITableViewDelegate, UIPickerViewDataSource>
@property(strong,nonatomic) IBOutlet UILabel *testLabel; //label I use to test stuff instead of LOG
@property(strong,nonatomic) IBOutlet UIButton *findOwner; //button to summon pickerWheel
@property(strong,nonatomic) IBOutlet UIButton *findShip; //Button to confirm selection in picker and unhide tableView
@property(strong,nonatomic) NSArray *boatOwners; //Array for boat owners.
@property(strong,nonatomic) NSMutableArray *boatsForOwner; //array for boats, added by owner
@property(strong,nonatomic) IBOutlet UITableView *boatsTableView; //Table view
-(IBAction)findOwnerButtonPressed:(id)sender;
-(IBAction)findShipButtonPressed:(id)sender;
@property(strong, nonatomic) IBOutlet UIPickerView *shipOwners; //ship owner picker wheel
@property(strong,nonatomic)IBOutlet UILabel *infoLabel;
/*@property(strong,nonatomic)IBOutlet UILabel *nameLabel; //These was tested, but didn't work. Illegal assignment error.
@property(strong,nonatomic)IBOutlet UILabel *moreInfoLabel;
@property(strong,nonatomic)IBOutlet UITableViewCell *SimpleTableCell;*/
@end
这又是对 CargoViewController.m的控制（仅添加了相关部分）
#import "CargoViewController.h"
#import "SimpleTableCell.h"
@interface CargoViewController ()
@end
@implementation CargoViewController
@synthesize testLabel, findOwner, findShip,shipOwners, boatsTableView, infoLabel;
@synthesize boatOwners, boatsForOwner;
//When I try to synthesize name and infolabel in cell here, it does not work
//...more code...
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [boatsForOwner count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = @"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[SimpleTableCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.nameLabel.text = [boatsForOwner objectAtIndex:indexPath.row];
return cell;
}
我的问题是：
cell.nameLabel.text在对象上找不到UITableViewCell
哪个，根据
我的故事板是错误的（？）
有关更多信息，该表在我实现原型单元之前有效。在我只使用默认值之前。错误触发：
