Answer 1

Suppose you have four text fields with tags 100 and so on to 104. You will you Counter that shows how many cells you have in tableview.

         

for (int i=0; iLessThanCounter; i++) {
            
     NSIndexPath *indexPath = [NSIndexPath indexPathForRow: i inSection: 0];
                
     UITableViewCell *cell = [mytableview cellForRowAtIndexPath:indexPath];
                
     for (UIView *view in  cell.contentView.subviews){                
                    
           if ([view isKindOfClass:[UITextField class]]){
                        
                  UITextField* txtField = (UITextField *)view;
                        
                  if (txtField.tag == 100) {
                         NSLog(@"TextField.tag:%u and Data %@", txtField.tag, txtField.text);
                  }
                  if (txtField.tag == 101) {
                        NSLog(@"TextField.tag:%u and Data %@", txtField.tag, txtField.text);
                  }
                  if (txtField.tag == 102) {
                        NSLog(@"TextField.tag:%u and Data %@", txtField.tag, txtField.text);
                  }
                  if (txtField.tag == 103) {
                       NSLog(@"TextField.tag:%u and Data %@", txtField.tag, txtField.text);
                  }
                  if (txtField.tag == 104) {
                       NSLog(@"TextField.tag:%u and Data %@", txtField.tag, txtField.text);

                  } // End of isKindofClass 
              } // End of Cell Sub View
         }// Counter Loop
    }

This way will solve the purpose. But best way is to do it through delegates. – Jurisdiction

If you do have large number of views inside the cell this code will be ambiguous. You are conterminously checking tag on if conditions, even you are not using else if or the best tool for this scenario switch statement. And if you directly get the view for a specific tag then why do you iterate with a loop? – Westleigh

help me i have same logic – Neglect

perfect only for the visible cells in the tableview...but one cannot get data for the cells scrolled up. – Abohm

Answer 2

You can simply use viewWithTag to get your desired views. Suppose you have one imageview with tag 100 and one text view with tag 200.

UITableViewCell *cell = [mytableview cellForRowAtIndexPath:indexPath];

UIImageView *getImageView = (UIImageView*)[cell.contentView viewWithTag:100];
UITextField *getTextView = (UITextField*)[cell.contentView viewWithTag:200];

Answer 3

you need to create instance for each textField in your header file. Look at this sample demo

http://windrealm.org/tutorials/uitableview_uitextfield_form.php

You can access textfield's text property for getting the text value for a particular textfield

I have multiple textFields in a cell, & there are also multiple cells, – Explain

so you can keep references for all of them – Takara
