Question

我正在尝试在tableview单元格中加载自定义视图。确切地说，我有一个对象数组，我想使用自定义视图在单元格中加载内容。我的对象结构是：

{  ID = 1;  date = "2014-01-06";  n1 = 12;  n2 = 3;  n3 = 34;  n4 = 5; n5 = 44;  n6 = 24;  report = "<null>";  win = 123443; }

我试图在视图中显示n1，n2 ...的值，我制作了这个方法：

@interface MenuCell : UITableViewCell

@property (nonatomic, strong) BallView *ballView;
@property (nonatomic, strong) IBOutlet UILabel *labelDescription; 
@property (nonatomic, strong) IBOutlet UILabel *labelDetails;
@property (nonatomic, strong) IBOutlet UIView *ballsView;

+ (CGFloat)getCellHeight;

我的BallView.h

@interface BallView : UIView

@property (nonatomic, strong) IBOutlet UIImageView *imgSelectedBall;
@property (nonatomic, strong) IBOutlet UILabel *labelNo;
@property (nonatomic, strong) IBOutlet UIActivityIndicatorView *spinner;

+ (BallView*)showInView:(UIView*)parrentView xOrigin:(NSInteger)xOriginValue;

@end

我的BallView.m

+ (BallView*)showInView:(UIView*)parrentView xOrigin:(NSInteger)xOriginValue {
    NSArray* nibViews = [[NSBundle mainBundle] loadNibNamed:@"BallView" owner:self options:nil];
    BallView *modal = [nibViews objectAtIndex:0];
    modal.frame = CGRectMake(xOriginValue,ball_yOrigin, ball_width, ball_height);
    [modal setBackgroundColor:[UIColor greenColor]];
    [parrentView addSubview:modal];
    return modal; }

在UITableView委托方法的ViewController中，我尝试以这种方式加载信息（我用1号值进行了测试）：

 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
    {
        static NSString *CellIdentifier = @"NewsCell";
        MenuCell *cell = (MenuCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

        if (cell == nil) {
            NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"MenuCell_3" owner:self options:nil];
            for (id currentObject in topLevelObjects){
                if ([currentObject isKindOfClass:[UITableViewCell class]]){
                    cell =  (MenuCell *) currentObject;
                }
            }
        }

        __block TickteObj *obj   = [self.dataSourceArray objectAtIndex:indexPath.row];

        if (obj){        
            __block CGFloat leftMark = ball_offSet;
            for (int i = 1 ; i<5 ; i++){ //5 = my object has 6 numbers which must be displayed
                __block BallView  *ballView = [BallView showInView:cell.ballView xOrigin:leftMark];
                cell.ballView.labelNo.text = obj.n1;

                leftMark+=ball_offSet+ballView.frame.size.width;
            }
        }
        return cell;
    }

我需要帮助才能在我的单元格中加载值。谢谢！

您应该真正更改TickteObj提供的界面。它不应提供许多属性（n1，n2，... nx），而应提供基于索引的方法：

- (NSString *)nValueAtIndex:(NSInteger)index

并且可能在内部将n值存储在数组中。通过这种方式，无论有多少值都可以，并且您的循环可以轻松运行。
