przycisk wykrywania kliknij w widoku tabeli kod ios dla wielu wierszy i sekcji

Question

Chcę wykryć przycisk kliknij na widok tabeli z wieloma wierszami i sekcjami. Udało mi się to osiągnąć w przypadku pojedynczego rzędu, ale mam problem z tym, że nie wykryłem właściwej sekcji. mam kłopoty, aby wykryć, który przycisk sekcja ma użytkownik kliknął

poniżej jest zaktualizowany kod po problem jest rozwiązany

Detecting which UIButton was pressed in a UITableView

Answer 1

Cel 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 przede

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)) 
} 

Answer 2

Swift 3 

let clickedButtonIndexPath = self.tableView.indexPathForRow(at: touchPoint) 
     if(clickedButtonIndexPath != nil) 
     { 
      NSLog("index path.section ==%ld", Int(clickedButtonIndexPath!.section)) 
      NSLog("index path.row ==%ld", Int(clickedButtonIndexPath!.row)) 
      }
