Ios 检测是否轻触包含多个部分的UITableView的UITableViewCell中的按钮

我想在父UITableView包含多个部分的UITableView单元格上检测按钮点击

我可以在单节的情况下这样做，但在有多个节的情况下，我很难确定正确的节

我试图确定用户点击按钮的UITableViewCell对应的正确部分

以下是问题解决后的更新代码：

@property (strong, nonatomic) NSMutableArray* quantityArray;
@property (strong, nonatomic) NSMutableArray* rows; 

@synthesize quantityArray,rows;

- (void)viewDidLoad {
    [super viewDidLoad];

    quantityArray = [[NSMutableArray alloc] init];
    [self PluMinusFunction];
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
        //
        // Some code here.
        //         

    if (addBtnClicked || minusBtnClicked) {
        cell.lblCount.text = [[quantityArray objectAtIndex:indexPath.section-1]objectAtIndex:indexPath.row];
        addBtnClicked = NO;
        minusBtnClicked = NO;
    } else {
        cell.lblCount.text = [[quantityArray objectAtIndex:indexPath.section-1]objectAtIndex:indexPath.row];                
    }

        cell.btnMinus.tag = indexPath.row;
        cell.btnPlus.tag = indexPath.row;
        cell.lblCount.tag = indexPath.row;

        [cell.btnPlus addTarget:self action:@selector(addItem:) forControlEvents:UIControlEventTouchUpInside];

        if ([ cell.lblCount.text integerValue]!=0) {
            [cell.btnMinus addTarget:self action:@selector(deleteItem:) forControlEvents:UIControlEventTouchUpInside];
        }

        return cell;
    }
}

    for (int j=0; j <[itemArr count]; j++) {
        rows = [[NSMutableArray alloc] init];
        for (int i=0; i <[ [[itemArr objectAtIndex:j] objectForKey:@"itemList"]count]; i++) {
            [rows insertObject:@"0" atIndex:i];
        }
        [quantityArray insertObject:rows atIndex:j];
    }
    [self sum];
}

    NSMutableArray *subArray = [quantityArray objectAtIndex:section-1];
    [subArray replaceObjectAtIndex:row withObject: [NSString stringWithFormat:@"%ld",(long)LabelText]];
    [quantityArray replaceObjectAtIndex:section-1 withObject: subArray];
    addBtnClicked = YES;

    NSIndexPath* rowToReload = [NSIndexPath indexPathForRow:row inSection:section];
    NSArray* rowsToReload = [NSArray arrayWithObjects:rowToReload, nil];
    [self.tableView reloadRowsAtIndexPaths:rowsToReload withRowAnimation:UITableViewRowAnimationNone];
}

- (void)deleteItem:(UIButton*)button {
    CGPoint touchPoint = [button convertPoint:CGPointZero toView:self.tableView];
    NSIndexPath *clickedButtonIndexPath = [self.tableView indexPathForRowAtPoint:touchPoint];

    NSInteger row = clickedButtonIndexPath.row;
    NSInteger section = clickedButtonIndexPath.section;

    NSInteger  LabelValue =[[[quantityArray objectAtIndex:section-1]objectAtIndex:row]integerValue];

    if (LabelValue >= 1) {
        NSInteger  LabelText =[[[quantityArray objectAtIndex:section-1]objectAtIndex:row]integerValue] - 1;
        NSMutableArray *subArray = [quantityArray objectAtIndex:section-1];
        [subArray replaceObjectAtIndex:row withObject: [NSString stringWithFormat:@"%ld",(long)LabelText]];

        [quantityArray replaceObjectAtIndex:section-1 withObject: subArray];

-(void)addItem:(UIButton*) sender
{

CGPoint touchPoint = [sender convertPoint:CGPointZero toView:mainTable]; // maintable --> replace your tableview name
NSIndexPath *clickedButtonIndexPath = [mainTable indexPathForRowAtPoint:touchPoint];

 NSLog(@"index path.section ==%ld",(long)clickedButtonIndexPath.section);

 NSLog(@"index path.row ==%ld",(long)clickedButtonIndexPath.row);


}

Swift3

 func addItem(sender: UIButton)
{
    var touchPoint = sender.convert(CGPoint.zero, to: self.maintable)
    // maintable --> replace your tableview name
    var clickedButtonIndexPath = maintable.indexPathForRow(at: touchPoint)
    NSLog("index path.section ==%ld", Int(clickedButtonIndexPath.section))
    NSLog("index path.row ==%ld", Int(clickedButtonIndexPath.row))


}

Swift2及以上版本

func addItem(sender: UIButton)
 {
var touchPoint: CGPoint = sender.convertPoint(CGPointZero, toView: mainTable)
    // maintable --> replace your tableview name
var clickedButtonIndexPath: NSIndexPath = mainTable(forRowAtPoint: touchPoint)
NSLog("index path.section ==%ld", Int(clickedButtonIndexPath.section))
NSLog("index path.row ==%ld", Int(clickedButtonIndexPath.row))
}

在不使用
CGPoint
和假设用户界面的情况下，获取索引路径的更直接的方法是查看
.superview
。我认为这在实践中更可靠

- (myTableViewCell *)cellContainingView:(UIView *)view
{
    do {
        view = view.superview;
    } while (view != nil && ![view isKindOfClass:[myTableViewCell class]]);

    return (myTableViewCell *)view;
}

然后，您只需在按钮操作中执行此操作：

- (IBAction)myButtonPressed:(id)sender
{
    myTableViewCell *cell = [self cellContainingView:(UIView *)sender];
    NSIndexPath *path = [self.tableView indexPathForCell:cell];
}

斯威夫特5

 let touchPoint: CGPoint = sender.convert(.zero, to: tableViews)
    let clickedButtonIndexPath = self.tableViews.indexPathForRow(at: touchPoint)
            if(clickedButtonIndexPath != nil)
            {
                NSLog("index path.section ==%ld", Int(clickedButtonIndexPath!.section))
                NSLog("index path.row ==%ld", Int(clickedButtonIndexPath!.row))
               }

我得到了一个问题>在某些情况下，任何想法ab都是在随机场景中发生的，你面对哪种场景？你能检查一下这个问题吗？Swift代码是让touchPoint:CGPoint=sender.convertPoint（CGPointZero，toView:self.tableView）让buttonIndexPath=self.tableView.indexPathForRowAtPoint（touchPoint）！Swift 3.1-变量clickedButtonIndexPath=mainTable.indexPathForRow（在：接触点）
 let touchPoint: CGPoint = sender.convert(.zero, to: tableViews)
    let clickedButtonIndexPath = self.tableViews.indexPathForRow(at: touchPoint)
            if(clickedButtonIndexPath != nil)
            {
                NSLog("index path.section ==%ld", Int(clickedButtonIndexPath!.section))
                NSLog("index path.row ==%ld", Int(clickedButtonIndexPath!.row))
               }
