处理SECTIONS -我将NSIndexPath存储在一个自定义UITableViewCell中

在CLKIndexPricesHEADERTableViewCell.xib

在IB中添加UIButton到XIB -不要添加动作!

添加outlet @property (retain, nonatomic)

不要在IB中按CTRL+拖动动作(在下面的代码中完成)

@interface CLKIndexPricesHEADERTableViewCell : UITableViewCell
...
@property (retain, nonatomic) IBOutlet UIButton *buttonIndexSectionClose;
@property (nonatomic, retain) NSIndexPath * indexPathForCell;
@end

在viewForHeaderInSection(应该也适用于cellForRow....等等，如果你的表只有一个部分)

- viewForHeaderInSection is called for each section 1...2...3
- get the cell CLKIndexPricesHEADERTableViewCell 
- getTableRowHEADER just does the normal dequeueReusableCellWithIdentifier
- STORE the indexPath IN the UITableView cell
- indexPath.section = (NSInteger)section
- indexPath.row = 0 always (we are only interested in sections)

- (UIView *) tableView:(UITableView *)tableView1 viewForHeaderInSection:(NSInteger)section {


    //Standard method for getting a UITableViewCell
    CLKIndexPricesHEADERTableViewCell * cellHEADER = [self getTableRowHEADER];

.．.使用该节获取单元格的数据

.．.填进去

   indexName        = ffaIndex.routeCode;
   indexPrice       = ffaIndex.indexValue;

   //

   [cellHEADER.buttonIndexSectionClose addTarget:self
                                          action:@selector(buttonDELETEINDEXPressedAction:forEvent:)
                                forControlEvents:UIControlEventTouchUpInside];


   cellHEADER.indexPathForCell = [NSIndexPath indexPathForRow:0 inSection:section];


    return cellHEADER;
}

用户按下Section头上的DELETE按钮

- (void)buttonDELETEINDEXPressedAction:(id)sender forEvent:(UIEvent *)event
{
    NSLog(@"%s", __PRETTY_FUNCTION__);


    UIView *  parent1 = [sender superview];   // UiTableViewCellContentView
    //UIView *myContentView = (UIView *)parent1;

    UIView *  parent2 = [parent1 superview];  // custom cell containing the content view
    //UIView *  parent3 = [parent2 superview];  // UITableView containing the cell
    //UIView *  parent4 = [parent3 superview];  // UIView containing the table


    if([parent2 isMemberOfClass:[CLKIndexPricesHEADERTableViewCell class]]){
        CLKIndexPricesHEADERTableViewCell *myTableCell = (CLKIndexPricesHEADERTableViewCell *)parent2;

        //UITableView *myTable = (UITableView *)parent3;
        //UIView *mainView = (UIView *)parent4;

        NSLog(@"%s indexPath.section,row[%d,%d]", __PRETTY_FUNCTION__, myTableCell.indexPathForCell.section,myTableCell.indexPathForCell.row);

        NSString *key = [self.sortedKeysArray objectAtIndex:myTableCell.indexPathForCell.section];
        if(key){
            NSLog(@"%s DELETE object at key:%@", __PRETTY_FUNCTION__,key);
            self.keyForSectionIndexToDelete = key;
            self.sectionIndexToDelete = myTableCell.indexPathForCell.section;

            UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"Remove Index"
                                                                message:@"Are you sure"
                                                               delegate:self
                                                      cancelButtonTitle:@"No"
                                                      otherButtonTitles:@"Yes", nil];
            alertView.tag = kALERTVIEW_REMOVE_ONE_INDEX;
            [alertView show];
            [alertView release];
            //------
        }else{
            NSLog(@"ERROR: [%s] key is nil for section:%d", __PRETTY_FUNCTION__,myTableCell.indexPathForCell.section);
        }

    }else{
        NSLog(@"ERROR: [%s] CLKIndexPricesHEADERTableViewCell not found", __PRETTY_FUNCTION__);
    }
}

在这个例子中，我添加了一个删除按钮，所以应该显示UIAlertView来确认它

我将section和key存储到字典中，在VC中的ivar中存储关于section的信息

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {
   if(alertView.tag == kALERTVIEW_REMOVE_ONE_INDEX){
        if(buttonIndex==0){
            //NO
            NSLog(@"[%s] BUTTON:%d", __PRETTY_FUNCTION__,buttonIndex);
            //do nothing
        }
        else if(buttonIndex==1){
            //YES
            NSLog(@"[%s] BUTTON:%d", __PRETTY_FUNCTION__,buttonIndex);
            if(self.keyForSectionIndexToDelete != nil){

                //Remove the section by key
                [self.indexPricesDictionary removeObjectForKey:self.keyForSectionIndexToDelete];

                //sort the keys so sections appear alphabetically/numbericsearch (minus the one we just removed)
                [self updateTheSortedKeysArray];                

                //Delete the section from the table using animation
                [self.tableView beginUpdates];

                [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:self.sectionIndexToDelete]
                              withRowAnimation:UITableViewRowAnimationAutomatic];
                [self.tableView endUpdates];

                //required to trigger refresh of myTableCell.indexPathForCell else old values in UITableViewCells
                [self.tableView reloadData];
            }else{
                NSLog(@"ERROR: [%s] OBJECT is nil", __PRETTY_FUNCTION__);
            }
        }
        else {
            NSLog(@"ERROR: [%s] UNHANDLED BUTTON:%d", __PRETTY_FUNCTION__,buttonIndex);
        }
    }else {
        NSLog(@"ERROR: [%s] unhandled ALERTVIEW TAG:%d", __PRETTY_FUNCTION__,alertView.tag);
    }
}

这是简单的;做一个自定义单元格，并采取一个出口的按钮

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

    cell.yourButton.tag = indexPath.Row;

- (void)buttonPressedAction:(id)sender

将上述方法中的id更改为(UIButton *)

你可以通过sender。tag得到哪个按钮被点击的值。

我是这样做的。简洁明了:

- (IBAction)buttonTappedAction:(id)sender
{
    CGPoint buttonPosition = [sender convertPoint:CGPointZero
                                           toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:buttonPosition];
    ...
}

你可以使用标签模式:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
     NSString *identifier = @"identifier";
     UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
     if (cell == nil) {
         cell = [[UITableView alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
         [cell autorelelase];

         UIButton *button = [[UIButton alloc] initWithFrame:CGRectMake(10, 5, 40, 20)];
         [button addTarget:self action:@selector(buttonPressedAction:) forControlEvents:UIControlEventTouchUpInside];
         [button setTag:[indexPath row]]; //use the row as the current tag
         [cell.contentView addSubview:button];

         [button release];
     }

     UIButton *button = (UIButton *)[cell viewWithTag:[indexPath row]]; //use [indexPath row]
     [button setTitle:@"Edit" forState:UIControlStateNormal];

     return cell;
}

- (void)buttonPressedAction:(id)sender
{
    UIButton *button = (UIButton *)sender;
    //button.tag has the row number (you can convert it to indexPath)
}

这个问题分为两部分:

1)获取包含UIButton的UITableViewCell的索引路径

以下是一些建议:

Updating UIButton's tag in cellForRowAtIndexPath: method using index path's row value. This is not an good solution as it requires updating tag continuously and it does not work with table views with more than one section. Adding an NSIndexPath property to custom cell and updating it instead of UIButton's tag in cellForRowAtIndexPath: method. This solves multiple section problem but still not good as it requires updating always. Keeping a weak refence to parent UITableView in the custom cell while creating it and using indexPathForCell: method to get the index path. Seems a little bit better, no need to update anything in cellForRowAtIndexPath: method, but still requires setting a weak reference when the custom cell is created. Using cell's superView property to get a reference to parent UITableView. No need to add any properties to the custom cell, and no need to set/update anything on creation/later. But cell's superView depends on iOS implementation details. So it can not be used directly.

但是这可以使用一个简单的循环来实现，因为我们确定问题中的单元格必须在UITableView中:

UIView* view = self;
while (view && ![view isKindOfClass:UITableView.class])
    view = view.superview;
UITableView* parentTableView = (UITableView*)view;

因此，这些建议可以组合成一个简单而安全的自定义单元格方法来获取索引路径:

- (NSIndexPath *)indexPath
{
    UIView* view = self;

    while (view && ![view isKindOfClass:UITableView.class])
        view = view.superview;

    return [(UITableView*)view indexPathForCell:self];
}

从现在开始，这个方法可以用来检测哪个UIButton被按下了。

2)通知其他方按钮按下事件

在内部知道哪个UIButton在哪个自定义单元格中被按下后，这个信息需要被发送给其他方(最有可能是处理UITableView的视图控制器)。因此，这个按钮点击事件可以在类似于UITableView委托的didSelectRowAtIndexPath:方法的抽象和逻辑级别中处理。

可以使用两种方法:

a)委托:自定义单元可以有委托属性，可以定义协议。当按钮被按下时，它只是在它的委派属性上执行它的委派方法。但是在创建每个自定义单元格时，需要为它们设置这个委托属性。作为一种替代方法，自定义单元格也可以选择在父表视图的委托上执行它的委托方法。

b)通知中心:自定义单元格可以定义一个自定义的通知名称，并将该通知与userInfo对象中提供的索引路径和父表视图信息一起发布。无需为每个单元格设置任何内容，只需为自定义单元格的通知添加一个观察者就足够了。

Swift 2更新

下面是如何找出哪个按钮被点击+从该按钮的indexPath发送数据到另一个ViewController。我认为这是大多数人的重点!

@IBAction func yourButton(sender: AnyObject) {


     var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
        let indexPath = self.tableView.indexPathForRowAtPoint(position)
        let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath!)! as
        UITableViewCell
        print(indexPath?.row)
        print("Tap tap tap tap")

    }

对于那些使用ViewController类并添加tableView的人，我使用的是ViewController而不是TableViewController，所以我手动添加了tableView以便访问它。

下面是当点击按钮并传递单元格的indexPath.row时，将数据传递给另一个VC的代码

@IBAction func moreInfo(sender: AnyObject) {

    let yourOtherVC = self.storyboard!.instantiateViewControllerWithIdentifier("yourOtherVC") as! YourOtherVCVIewController



    var position: CGPoint = sender.convertPoint(CGPointZero, toView: self.tableView)
    let indexPath = self.tableView.indexPathForRowAtPoint(position)
    let cell: UITableViewCell = tableView.cellForRowAtIndexPath(indexPath!)! as
    UITableViewCell
    print(indexPath?.row)
    print("Button tapped")


    yourOtherVC.yourVarName = [self.otherVCVariable[indexPath!.row]]

    self.presentViewController(yourNewVC, animated: true, completion: nil)

}
