检测按钮单击表视图ios xcode多行和节 [英] detect button click in table view ios xcode for multiple row and section

问题描述

我想检测具有多个行和部分的表格视图上的按钮单击。我能够在单排的情况下实现它，但我遇到麻烦，它没有检测到正确的部分。 我无法检测用户点击了哪个部分按钮

I want to detect the Button click on table view with multiple row and section. I was able to acheive it on case of single row but I got trouble that it didnt detect correct section. I got trouble to detect which section button has user clicked

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 {
    ====================================================

        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;
    }
}

#pragma mark - Pluys Minus Button

-(void) PluMinusFunction
{
    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];
}


#pragma mark - UIButton selector

-(void)addItem:(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  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];
    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];
        addBtnClicked = YES;

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


}

我希望如下图所示

也为我的问题提供了解决方案

检测在UITableView中按下哪个UIButton

推荐答案

Objective-C

-(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

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))
}
