from How do I create a text field?
To create a text field, use the UITextField class, as shown in Listing 11.
Listing 11: Creating a text field
CGRect textFieldFrame = CGRectMake(0.0, 0.0, 100.0, 30.0);
UITextField *textField = [[UITextField alloc] initWithFrame:textFieldFrame];
[textField setBorderStyle:UITextFieldBorderStyleBezel];
[textField setTag:1234];
[textField setTextColor:[UIColor blackColor]];
[textField setFont:[UIFont systemFontOfSize:20]];
[textField setDelegate:self];
[textField setPlaceholder:@"<enter text>"];
[textField setBackgroundColor:[UIColor whiteColor]];
textField.keyboardType = UIKeyboardTypeDefault;

Use this method for text field creation, and use setTag: function for setting unique ID. If you want exact name for each text field, then you can make your own text field class that will be derived from base text field class and it will have the NSString member name.

Hai Benoit, I got result with your help. Thanks!
Assign tag for each UITextField..
then access the textField using
UITextField *tf=(UITextField *)[yourView viewWithTag:tag];

include this line txt.tag=i; in ur for loop
KingofBliss
then retrieve the value as follows,for(int i=1; i<=5;i++) { UITextField *tf=(UITextField *)[self.view viewWithTag:i]; [mutArr addObject:tf.text];}
for (int i=0; i<[checklistArray count]; i++) {
[self addUITextFieldMethod:i]
}
-(void) addUITextFieldMethod:(int)y {
UITextField *textField = [[UITextField alloc]initWithFrame:CGRectMake(20, 70*y+40, 280, 31)];
textField.placeholder = @"Click here to type";
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.font = [UIFont systemFontOfSize:15];
textField.textAlignment = NSTextAlignmentLeft;
textField.returnKeyType = UIReturnKeyDefault;
int DropDownTag = [[NSString stringWithFormat:@"10%d",y]integerValue];
textField.tag = DropDownTag ;
textField.delegate = self;
[textField addTarget:self action:@selector(returnFromKeyboard:) forControlEvents:UIControlEventEditingDidEndOnExit];
[scrollViewChecklist addSubview:textField];
}
int textFieldTagValue = textField.tag;
/****************Code In Your Method****************/
UITextField *myTextField = (UITextField *)[self.view viewWithTag:textFieldTagValue];
myTextField.text = [arrayTest objectAtIndex:indexPath.row];
