聲明失敗 - [UITableView _configureCellForDisplay：forIndexPath：]，

Question

我是新來的Xcode試圖顯示一些數據在tableview中使用自定義單元格獲得*** Assertion failure in -[UITableView _configureCellForDisplay:forIndexPath:]，錯誤。請任何人都可以指導我。提前致謝。我正在使用storyboard來創建UITableview。

這裏是我的Viewcontroller.m代碼

#import "ViewController.h" 
#import "CustomCell.h" 
@interface ViewController() 

{ 
    NSArray *profilehd; 
    NSArray *profileimg; 
} 

@end 

@implementation ViewController 

@synthesis tableview; 

-(void)viewDidLoad 
{ 
    tablevw.dataSource = self; 
    tablevw.delegate = self; 

    profilehd = [[NSArray alloc]initWithObjects:@"Name",@"Email",@"Skype", nil]; 
    profileimg = [[NSArray alloc]initWithObjects:@"about_me_icon.png",@"email_icon.png",@"skype_icon.png", nil]; 

    [super viewDidLoad]; 

    // Do any additional setup after loading the view, typically from a nib. 
} 


#pragma mark:-UITableView Datasource and Delegate Methods 

-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView 
{ 
    return 1; 
} 

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
    return [profilehd count]; 
} 

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    static NSString *cellIdentifier = @"CellID"; 

    CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; 

    if (cell == nil) 
    { 
     cell.ProfilehdLabel.text = [profilehd objectAtIndex:indexPath.row]; 
     cell.profileImgvw.image = [UIImage imageNamed:[profileimg objectAtIndex:indexPath.row]]; 
     } 

    return cell; 
} 

CustomCell.m

@property (strong, nonatomic) IBOutlet UILabel *profilehdLabel; 
@property (strong, nonatomic) IBOutlet UIImageView *profileImgvw;

你永遠不會創建一個單元格，你只是嘗試重用取出的細胞。所以，

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath; 
{ 
    static NSString *cellIdentifier = @"CellID"; 
    CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier]; 
    if (!cell) { 
     // if cell is empty create the cell 
     cell = [[CustomCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier]; 
    } 

    cell.ProfilehdLabel.text = [profilehd objectAtIndex:indexPath.row]; 

cell.profileImgvw.image = [UIImage imageNamed:[profileimg objectAtIndex:indexPath.row]]; 

    return cell; 
}
