Question

我在填充表时遇到问题。我创建了一个自定义视图，在视图中我创建了一个tableview。下面给出了UIView子类的代码。出现该表并调用所有代理。

根据代理创建24个单元格并显示它们但不显示文本或任何其他单元格内容。我无法更改任何单元格属性，包括单元格背景颜色。

- (id)initWithFrame:(CGRect)frame andCellHeight:(CGFloat)cellh{
    self = [super initWithFrame:frame];
    if(self){

        [self initTimeArray];
        [self initTable];
    }
    return self;
}


- (void) initTable{
    timeLine = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, self.frame.size.width,self.frame.size.height )];
    timeLine.backgroundColor = [ UIColor clearColor];
   timeLine.separatorStyle = UITableViewCellSeparatorStyleNone;
    timeLine.rowHeight = cellHeight;
    timeLine.delegate =self;
    timeLine.dataSource = self;
    [self addSubview:timeLine];
}


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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:nil];

    if (cell == nil) {
        cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
        [cell setBackgroundColor:[UIColor blueColor]];

    }


    UIView *lineView = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 28, 2)];
    [lineView setBackgroundColor:[UIColor grayColor]];
   // [cell.contentView addSubview:lineView];
    UILabel *time = [[UILabel alloc]initWithFrame:CGRectMake(0, 10, 40 , 40)];
    time.text = @"Test text";
    time.textColor = [ UIColor  redColor];
    cell.textLabel.text = @"Another test Text";
    [time setFont:[UIFont systemFontOfSize:14]];
    [cell.contentView addSubview:time];

    return cell;

}
-(void) initTimeArray
{
    timeArray = [NSArray arrayWithObjects:@"12 PM", @"11 PM" ,
                 @"10 PM", @"9 PM", @"8 PM" , @"7 PM" ,
                 @"6 PM", @"5 PM", @"4 PM" , @"3 PM" ,
                 @"2 PM", @"1 PM",   @"12 PM", @"11 AM" ,
                 @"10 AM", @"9 AM", @"8 AM" , @"7 AM" ,
                 @"6 AM", @"5 AM", @"4 AM" , @"3 AM",
                 @"2 AM", @"1 AM" , @"12 AM", nil];
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{

    return 24;
}

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

表格单元格显示为空
