ios - 获取索引路径 如果用户在 UITableview 中编辑 UITextfield

Question

我正在使用如下图所示的 UITableview。如果我输入单价和数量，我需要计算。但是现在我不知道如何获取 UITableView 中两个文本框的索引路径。在 UITableView 中，如果单击按钮转到 didSelectRowAtIndexPath 方法。当我在 qty 和 unitprice 文本框中输入时，没有调用相同的方法。

InvoiceMainViewController.h

    #import <UIKit/UIKit.h>
    #import <QuartzCore/QuartzCore.h>

    @class InvoiceGridViewController;

    @protocol InvoiceTableCellProtocoll <NSObject>
    -(void) didPressButton:(InvoiceGridViewController *)theCell; 
    @end

    @interface InvoiceGridViewController : UITableViewCell {
             id<InvoiceTableCellProtocoll> delegationListener; }

    @property (nonatomic,assign) id<InvoiceTableCellProtocoll>  delegationListener;
    @property (nonatomic,retain) IBOutlet UITextField *invoiceItem;
    @property (nonatomic,retain) IBOutlet UITextField *invoiceUnitPrice;
    @property (nonatomic,retain) IBOutlet UITextField *invoiceQty;
    @property (nonatomic,retain) IBOutlet UITextField *invoiceTaxRate; 

    @property (nonatomic,retain) IBOutlet UILabel *invoiceItemId;
    @property (nonatomic,retain) IBOutlet UILabel *invoiceCurrencyId;
    @property (nonatomic,retain) IBOutlet UILabel *invoiceTaxRateId;

    @property (nonatomic,retain) IBOutlet UILabel *totalItemTax; @property
    @property (nonatomic,retain) IBOutlet UILabel *converstionMessage;

    -(IBAction)deleteSel:(id)sender;
    -(void)delFileSel; 
    @end

InvoiceMainViewController.m

#import <UIKit/UIKit.h>
#import "SBPickerSelector.h"
#import <Foundation/Foundation.h>
#import "AFHTTPRequestOperationManager.h"
#import "AFURLResponseSerialization.h"
#import "AFURLRequestSerialization.h"
#import "InvoiceGridViewController.h"


@interface InvoiceMainViewController : UIViewController<UITableViewDataSource, UITableViewDelegate,NSXMLParserDelegate,UITextFieldDelegate,InvoiceTableCellProtocoll>{

Answer 1

你可以通过多种方式做到这一点

类型 -1

// get the current visible rows

NSArray *paths = [yourtableName indexPathsForVisibleRows];
NSIndexPath *indexpath = (NSIndexPath*)[paths objectAtIndex:0];

2 型

你可以得到你触摸了哪个单元格

 CGPoint touchPoint = [sender convertPoint:CGPointZero toView: yourtableName];
NSIndexPath *clickedButtonIndexPath = [mainTable indexPathForRowAtPoint: yourtableName];

Type-3

 add `TapGestuure ` for get the current cell.

Type-4

- (void) textFieldDidEndEditing:(UITextField *)textField {
CGRect location = [self convertRect:textField.frame toView:self.tableView];
NSIndexPath *indexPath = [[self.tableView indexPathsForRowsInRect:location] objectAtIndex:0];

// Save the contents of the text field into your array:
[yourArray replaceObjectAtIndex:indexPath.row withObject:textField.text];
}
