tablecell背景仅显示自定义单元格，但显示自定义单元格使其无法选择

标签： ios objective-c uitableview background didselectrowatindexpath

我创建了一个自定义tableCell当我通过backgroundView将xib连接到文件所有者时，我成功地将项目显示在我的表中。问题是我无法选择一行并获得回报。

table cells work

如果我取消选择backgroundView，那么我的自定义单元格不会填充，但我可以选择一个单元格并提取通知。我显然希望这两个项目都有效。显示我的自定义单元格，并能够选择特定单元格。 clicking works

答案 0 :(得分：1)

抛开你应用程序的奇怪行为，我注意到你没有以通常的方式呈现表格单元格。所以首先尝试以通常的方式呈现它：

  1. 在viewDidLoad中注册nib，因为您在xib中创建了单元格

    - (void)viewDidLoad {
    [super viewDidLoad];

    // Arrays for filling table cells
    _HomeImages=@[@"ic_bengals_nfl",@"ic_bengals_nfl",@"ic_bengals_nfl",@"ic_bengals_nfl", ];
    _AwayImages=@[@"ic_bears_nfl",@"ic_bears_nfl",@"ic_bears_nfl",@"ic_bears_nfl", ];
    _SportGameInfo=@[@"7:00pm",@"8:00pm",@"9:00pm",@"10:00pm",];
    [self.PendingChal registerNib:[GameTableCell nib] forCellReuseIdentifier:CellIdentifier];
    [self.ActiveChal registerNib:[GameTableCell nib] forCellReuseIdentifier:CellIdentifier];
}

  2. 在- tableView:cellForRowAtIndexPath:中将可重复使用的单元格取消并将其返回

  3. 你不需要在tableViewCell的init方法中加载nib删除

    NSArray * topLevelObjects = [[NSBundle mainBundle] loadNibNamed：@＆＃34; GameTableCell＆＃34;所有者：自我选择：无; self = [topLevelObjects objectAtIndex：0];
