Can'T click textView when delegate is set - ios

Question

I have an App with 2 Views on top of each other and on the overlaying view there is a UITextView and a UIButton next to it.
When I click the Button once the TextView should become smaller (from CGRectMake(0, 50, self.view.frame.bounds.size.width, 100) to CGRectMake(0, 50, self.view.frame.bounds.size.width, 50)) and on the second click it should become bigger again.
Here's the code how I manage this:
-(IBAction)buttonTouched:(id)sender {
if(counter == 1) {
[self.textView removeFromSuperview];
self.textView = nil;
self.textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.bounds.size.width, 50)];
[self.overlayView addSubview:self.textView];
counter = 2;
} else {
[self.textView removeFromSuperview];
self.textView = nil;
self.textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.bounds.size.width, 100)];
[self.overlayView addSubview:self.textView];
counter = 1;
}
}
My problem is that when I do it like this, I can't handle the delegate methods for the UITextView like textViewDidBeginEditing:(UITextView *)textView without setting the delegate. But when I set the delegate like self.textView.delegate = self after recreating the TextView, nothing happens when I click on it. No keyboard appears and the events aren't called either.
Any suggestions?

Answer 1

Try to alloc your textView in the ViewDidLoad,
self.textView = [[UITextView alloc]init];
and on the button click use
[self.textView setFrame:CGRectMake(0, 50, self.view.frame.bounds.size.width, 50)];
and
[self.textView setFrame:CGRectMake(0, 50, self.view.frame.bounds.size.width, 100)];

-(IBAction)buttonTouched:(id)sender {
if(counter == 1) {
[self.textView removeFromSuperview];
self.textView = nil;
self.textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.bounds.size.width, 50)];
[self.overlayView addSubview:self.textView];
counter = 2;
} else {
[self.textView removeFromSuperview];
self.textView = nil;
self.textView = [[UITextView alloc] initWithFrame:CGRectMake(0, 50, self.view.frame.bounds.size.width, 100)];
[self.overlayView addSubview:self.textView];
counter = 1;
}
}
In above code only change "self.view.bounds.size.width" insted of "self.view.frame.bounds.size.width"
Assign delegate "self.textView.delegate=self" before that in .h file
#interface ViewController : UIViewController

Try this,
Initialise and addSubview self.textView in viewDidLoad and set self.textView.delegate = self;
-(IBAction)buttonTouched:(id)sender {
if(counter == 1) {
self.textView.frame = CGRectMake(0, 50, self.view.frame.bounds.size.width, 50);
counter = 2;
} else {
self.textView.frame = CGRectMake(0, 50, self.view.frame.bounds.size.width, 100);
counter = 1;
}
[self.overlayView bringSubviewToFront:self.textView];
}
Just change the frame of self.textView in buttonTouched:
