Answer 1

Please try to use this one.I hope it may help you. But you should assign tag 1 to email and 2 to password text field.
-(IBAction)loginBtnPressed:(IBAction)sender
{
UITableViewCell *emailCell = [self.tblView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
UITableViewCell *passwordCell = [self.tblView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0]] ;//pass
UITextField *emailTxtFLd = (UITextField *)[emailCell viewWithTag:1];
UITextField *passwordTxtFLd = (UITextField *)[passwordCell viewWithTag:2];
NSLog(#"Email : %#",emailTxtFLd.text);
NSLog(#"Password : %#",passwordTxtFLd.text);
}

You do one thing, when you add textFiled as a subView to the cell, set a tag to the textFiled like as given,
[textField setTag:-1];
And when you want to get the text from the textFiled, follow the steps below.
// Getting email
CustomCell *tableCell = (CustomCell*)[myTableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0]];
UITextField *myTextField = (UITextField *)[tableCell viewWithTag:-1];
NSString *emailString = [myTextField text];
NSLog(#"~~~~ email: %#", emailString);
// Getting Password
tableCell = [myTableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0]];
myTextField = (UITextField *)[tableCell viewWithTag:-1];
NSString *passwordString = [myTextField text];
NSLog(#"~~~~ password: %#", passwordString);
Hope this will help you :)

Since both cells are visible, you can just ask for them this way:
UITableViewCell *emailCell = [myTableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:0 inSection:0] //email
UITableViewCell *passwordCell = [myTableView cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1 inSection:0] //password
Then assuming both UITableViewCell have a property in their header exposed for the UILabel you can do:
emailCell.myLabel.text //Value of the text in the cell

If email and password has allocated then You can directly access them in your IIBAction method like that
in your .h file delcare this to email and password UItextfield
#interface ViewController : UIViewController
{
UITextField *email;
UITextField *pass;
}
Now alloc and add it in your cell
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
email = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 320, 140)];
pass = [[UITextField alloc] initWithFrame:CGRectMake(0, 0, 320, 140)];
}
// Table View Data Source methods
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 2;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell=[tableView dequeueReusableCellWithIdentifier:nil];
if(cell==nil)
{
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if(indexPath.row==0)
{
[cell addSubview:email];
}
if(indexPath.row==1)
{
[cell addSubview:pass];
}
return cell;
}
Now apply this IBAction on your login button
- (IBAction)loginBtnTouchUpInside:(id)sender
{
NSLog(#"email ==== %#",email.text);
NSLog(#"pass ==== %#",pass.text);
NSString *strEmail = email.text;
NSString *strPassword = pass.text;
}
I hope this is works for you

The easiest way is, save the textField value in a separate string in textField delegate like below.
-(void)textFieldDidEndEditing:(UITextField *)textField{
stringEmail = textField.text;
}
and use the string value for further process.Do it for both by setting tag.
Thank You.

-(void)ActivateLogin{
NSIndexPath *tmpIndexPath0 = [NSIndexPath indexPathForRow:0 inSection:0];
NSIndexPath *tmpIndexPath1 = [NSIndexPath indexPathForRow:1 inSection:0];
CustomCell *cellCopy0 =(CustomCell*) [tableViewName cellForRowAtIndexPath:tmpIndexPath0];
CustomCell *cellCopy1 =(CustomCell*) [tableViewName cellForRowAtIndexPath:tmpIndexPath1];
NSString *strEmail = #""; NSString *strPassword = #"";
strEmail = cellCopy0.tf.text;
strPassword = cellCopy1.tf.text;
if(![strEmail isEqualToString:#""] && ![strPassword isEqualToString:#""]){
... //Do what you want to do with the data
}
else{
//Alert user to enter credentials
}
}
