不会调用UITableView委托和dataSource方法-UITableViewdelegateanddataSourcemethodsnotgettingcalled

16  

Can you please write the code that you have written on your cellForRowAtIndexPath: method? Because i can't find anything wrong with your code.

你能写一下你在cellForRowAtIndexPath：方法上写的代码吗？因为我发现你的代码没有任何问题。

Are you calling your UIView from some other ViewController? If yes, how?

你是从其他ViewController调用你的UIView吗？如果有，怎么样？

I have done something like this once. I declared a method in the UIView like this :

我曾经做过这样的事情。我在UIView中声明了一个方法，如下所示：

- (void)setUpTableView{
    self.tableview.delegate=self;
    self.tableview.dataSource=self;
}

And then i called the setUpTableView from the view controller i added this view to, like this :

然后我从视图控制器调用setUpTableView我添加了这个视图，如下所示：

[self.yourView setUpTableView]; 

This might help. Thanks.

这可能有所帮助。谢谢。

I had a similar problem, my solution was because I did not set the number of sections to 1.

我有类似的问题，我的解决方案是因为我没有将部分数量设置为1。

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    // Return the number of sections.
    return 1;
}

You should declare your view like this @interface MyView : UIView

您应该声明您的视图@interface MyView：UIView

BTW: I would have a ViewController that "controls" your view and your tableview, and have the ViewController be the delegate and datasource of the table view.

顺便说一句：我会有一个ViewController“控制”你的视图和你的tableview，并让ViewController成为表视图的委托和数据源。

You do not need to use a UIViewController, that's just a smokescreen. You also do not need to add to the .h, although you should do that anyway because Xcode will complain otherwise, and you won't get method name auto complete.

你不需要使用UIViewController，这只是一个烟幕。你也不需要添加到.h，尽管你应该这样做，因为Xcode会抱怨，否则你不会自动完成方法名称。

I just wrote a test project that embeds a table view in a normal UIView and it works fine. Just make sure your initialization code is being called. I bet you need to move it to awakeFromNib.

我刚刚编写了一个测试项目，在普通的UIView中嵌入了一个表视图，它运行正常。只需确保调用您的初始化代码。我打赌你需要将它移动到awakeFromNib。

I ran into the same issue once, what silly mistake I did was inside initWithCoder I called [super init]. TableView was in xib

我曾经遇到过同样的问题，我在initWithCoder里面犯了什么愚蠢的错误，我调用了[super init]。 TableView在xib中

-(id) initWithCoder:(NSCoder *)aDecoder
{
    self = [super init]
}

Instead of

代替

-(id) initWithCoder:(NSCoder *)aDecoder
{
    self = [super initWithCoder:aDecoder];
}

Just check if that's not the case

只是检查是否不是这种情况

Try changing your UIViewto UIViewController and in viewDidLoad, call

尝试更改您的UIViewto UIViewController并在viewDidLoad中调用

[[UITableView alloc] initWithFrame:style:] to create your Table View.

[[UITableView alloc] initWithFrame：style：]创建表视图。

Set self as the delegate and data source like you did above, and then add this UITableView as Subview in this Controller.

像上面一样将self设置为委托和数据源，然后在此Controller中将此UITableView添加为Subview。

try this:

尝试这个：

override func numberOfSections(in tableView: UITableView) -> Int {
    return 1
}

i had this stupid problem too

我也有这个愚蠢的问题
