how to add a textfield by pressing a button - ios

Question

I'm trying to figure out how to add a textfield in a view in my iphone app by clicking on a button. Is it possible?
I thought it should be as easy as this. But it's not working.
- (IBAction)addText:(id)sender
CGRect textField = CGRectMake(0.0, 0.0, 100.0, 30.0);
UITextField *textField = [[UITextField alloc] initWithFrame:textField];

Hi John yes you can create uitextfield after clicking the button for that you have to write code as such below
- (IBAction)addText:(id)sender
{
CGRect textfieldFrame = CGRectMake(0.0, 0.0, 100.0, 30.0);
UITextField *textField = [[UITextField alloc] initWithFrame:textfieldFrame];
textField.borderStyle = UITextBorderStyleRoundedRect;
textField.font = [UIFont systemFontOfSize:15];
textField.placeholder = #"enter text";
textField.autocorrectionType = UITextAutocorrectionTypeNo;
textField.keyboardType = UIKeyboardTypeDefault;
textField.returnKeyType = UIReturnKeyDone;
textField.clearButtonMode = UITextFieldViewModeWhileEditing;
textField.contentVerticalAlignment = UIControlContentVerticalAlignmentCenter;
textField.delegate = self;
[self.view addSubview:textField];
}

If this code not work, mean your IBAction of UIButton not work put NSLog in IBAction or write UITextView global variable, because maybe it is super call dealloc your UITextView. Or maybe your CGRectMake(0.0, 0.0, 100.0, 30.0) frame out of your view exceed max with or max height and you not see its.
- (IBAction)addText:(id)sender {
CGRect textFieldFrame = CGRectMake(0.0, 0.0, 100.0, 30.0);
UITextField *textField = [[UITextField alloc] initWithFrame:textFieldFrame];
textField.delegate = self;
[self.view addSubview:textField];
// or add to you wanted view
[yourView addSubview:textField];
}
