如何自定义表视图单元格

Question

我正在尝试在cellFotRowAtIndexPath方法中自定义表格视图单元格，但未应用这些样式。

我将代码放在错误的位置吗？

 (void)viewDidLoad {
    [super viewDidLoad];

    self.buttonTitles = [[NSArray alloc] initWithObjects:@"1 Die", @"2 Dice", @"3 Dice", @"4 Dice", @"5 Dice", @"6 Dice", @"7 Dice", @"8 Dice", @"Roll with a Button", nil];
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


#pragma mark - Table view data source

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

    return 1;
}

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

    return buttonTitles.count;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"settingsCell" forIndexPath:indexPath];

    // Configure the cell...
    UIFont *cellFont = [UIFont fontWithName:@"Raleway-Thin" size:14];

    NSString *titles = [self.buttonTitles objectAtIndex:indexPath.row];
    cell.textLabel.text = titles;
    cell.textLabel.font = cellFont;
    cell.textLabel.textColor = [UIColor whiteColor];
    cell.textLabel.textAlignment = NSTextAlignmentCenter;
    cell.backgroundColor = [UIColor darkGrayColor];

    return cell;
}

更新

在视图调试器中有空单元格：

Answer 1

tableView:numberOfRowsInSection:中有这一行。

return buttonTitles.count;

这是引用名为buttonTitles的实例变量，而不是viewDidLoad中指定的属性。将行更改为读取

return self.buttonTitles.count;

您还可以删除buttonTitles实例变量的声明。你可能不需要它。

Answer 2

您尚未为tableview设置委托 以下代码将起作用

 -(void)viewDidLoad {

    [super viewDidLoad];

    self.buttonTitles = [[NSArray alloc] initWithObjects:@"1 Die", @"2 Dice", @"3 Dice", @"4 Dice", @"5 Dice", @"6 Dice", @"7 Dice", @"8 Dice", @"Roll with a Button", nil];
    UITableView *myTableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 0, 300, 400)];
    myTableView.delegate = self;
    myTableView.dataSource = self;
    [self.view addSubview:myTableView];
}

 -(void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

 -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {

    return 1;
}

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

    return buttonTitles.count;
}

 -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"settingsCell"];

    if(!cell){
        cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"settingsCell"];
    }




 // Configure the cell...
    UIFont *cellFont = [UIFont fontWithName:@"Raleway-Thin" size:14];

    NSString *titles = [self.buttonTitles objectAtIndex:indexPath.row];
    cell.textLabel.text = titles;
    cell.textLabel.font = cellFont;
    cell.textLabel.textColor = [UIColor whiteColor];
    cell.textLabel.textAlignment = NSTextAlignmentCenter;
    cell.backgroundColor = [UIColor darkGrayColor];

    return cell;
}

从IB中选择单元格和属性检查器，将TableView样式更改为自定义
