Get indexpath If user edit the UITextfield in UITableview - ios

Question

I'm using the UITableview like below image. If i typing Unit price and Qty i need to calculate. But now i dont know how to get indexpath for two text box in UITableView . In UITableView if button clicking goes to didSelectRowAtIndexPath method. Same method not calling when I typing in qty and unitprice textbox.
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

Answer 1

you can do this in various methods
Type -1
// get the current visible rows
NSArray *paths = [yourtableName indexPathsForVisibleRows];
NSIndexPath *indexpath = (NSIndexPath*)[paths objectAtIndex:0];
Type-2
you can get which cell you touched
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];
}

Try this one
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController
- (void)viewDidLoad
{
[super viewDidLoad];
firstTxt.delegate = self;
secondTxt.delegate = self;
// Do any additional setup after loading the view, typically from a nib.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField{
NSLog(#"textFieldShouldBeginEditing");
textField.backgroundColor = [UIColor colorWithRed:220.0f/255.0f green:220.0f/255.0f blue:220.0f/255.0f alpha:1.0f];
return YES;
}
- (void)textFieldDidBeginEditing:(UITextField *)textField{
NSLog(#"textFieldDidBeginEditing");
}
- (BOOL)textFieldShouldEndEditing:(UITextField *)textField{
NSLog(#"textFieldShouldEndEditing");
textField.backgroundColor = [UIColor whiteColor];
return YES;
}
- (void)textFieldDidEndEditing:(UITextField *)textField{
NSLog(#"textFieldDidEndEditing");
[tableView reloadData];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
NSLog(#"touchesBegan:withEvent:");
[self.view endEditing:YES];
[super touchesBegan:touches withEvent:event];
}

Answer 3

In textfield delegate method you can get the indexpath of row or you can directly get the textfields text
-(void)textFieldDidEndEditing:(UITextField *)textField
{
CGPoint hitPoint = [txtfield convertPoint:CGPointZero toView:tbl];
hitIndex = [tbl indexPathForRowAtPoint:hitPoint];
int localCount = [txtfield.text intValue];
}

Subclass your UITableViewCells. Create a protocol for each cell, with methods like cellName:(UITableViewCell*)cellName didSelectItem:(Item*) item. You can find more info here.
In the UITableViewCell set your UITextView delegate to self, and implement the protocol. textFieldShouldReturn: method, will indicate when the user is typing, so inside you will call [self.delegate cellName:self didEditText:textField.text].
In your MainViewController tableView: cellForRowAtIndexPath: set the UITabelViewCell's delegates, and implement the protocols.
So you will know in MainViewController when a user has typed in any of your textfields, independently from the table row number.
