Getting TextField Text On Button Click - ios

Question

I am developing an IOS App. I am creating a text field and a button dynamically, and I want to get textfield's text on button click, but I'm getting an error:
[UIView setText:]: unrecognized selector sent to instance
Here is my code:
- (IBAction)customFieldAdd:(id)sender{
[_addfieldArray addObject:_field];
x = 10;
y = 10;
for( int i = 0; i < [_addfieldArray count]; i++ ) {
UITextField *copyfield = [[UITextField alloc]initWithFrame:CGRectMake(5.0, x + _field.frame.size.height, 195.0f, 30.0f)];
[copyfield setDelegate:self];
[copyfield setTag:i];
[_filterPossibleValueView addSubview:copyfield];
x = x+_field.frame.size.height+10;
UIButton *copyAddButton = [[UIButton alloc]initWithFrame:CGRectMake(202.0f, y + _addField.frame.size.height, 30.0f, 30.0f)];
[copyAddButton setTag:i];
[copyAddButton addTarget:self action:#selector(customFieldDelete:) forControlEvents:UIControlEventTouchUpInside];
[_filterPossibleValueView addSubview:copyAddButton];
y = y+_addField.frame.size.height+10;
count++;
}
}
- (IBAction)customFieldDelete:(id)sender{
UIButton *button = (UIButton*)sender;
NSInteger index = button.tag;
// [_addfieldArray removeObjectAtIndex:index];
UITextField *field = [_filterPossibleValueView viewWithTag:index];
NSString *myText = field.text;
}

Answer 1

The default value for the tag property is 0, and you are setting that value to one of the text fields. So, when you try to get the view with tag == 0, it will have more than one view with that tag.
You should use an offset when setting the tag:
[copyfield setTag:kOffset + i];
...
[copyAddButton setTag:kOffset*2 + i]; // note that the button and the text field should not have the same tag either
where kOffset is defined (for example) like this:
let kOffset: Int = 1000
Then, to get the text field's text, you can use:
NSInteger tag = button.tag - kOffset;
UITextField *field = [_filterPossibleValueView viewWithTag:tag];
NSString *myText = field.text;
