Position UIButton in UITextview - ios

Question

I would like to place a "forgot?" Button into my Password Textfield. If nothing is in the Textfield the user should be able to click it and another ViewController should pop up. The only thing I managed to do is what you can see in the picture down below. My problem is that the button is not clickable and that it is not on the same level as the placeholder text. Any ideas on how to solve this two problems?
let button = UIButton(type: .custom)
button.setTitle("vergessen?", for: .normal)
button.frame = CGRect(x: CGFloat(0), y: CGFloat(0), width: CGFloat(100), height: CGFloat(100))
button.addTarget(self, action: #selector(self.refresh), for: .touchUpInside)
passwordTextField.rightView = button
passwordTextField.rightViewMode = .unlessEditing

Answer 1

In the file you have subclassed from my answer add another function in that file
// Modify the values as required
override func rightViewRect(forBounds bounds: CGRect) -> CGRect {
let offset = -20
let width = 100
let height = width
let x = Int(bounds.width) - width - offset
let y = offset
let rightViewBounds = CGRect(x: x, y: y, width: width, height: height)
return rightViewBounds
}
Now you can remove the follow line
button.frame = CGRect(x: CGFloat(0), y: CGFloat(0), width: CGFloat(100), height: CGFloat(100))
Output
And regarding the button click event. Remove your code as you mention its not connected
IBAction func refresh(_ sender: Any) { }
And add the following code in the same file where the button is created.
#objc func refresh() {
// your vc code here
print("in refresh")
}
The above code hooks in with addTarget code you have.
button.addTarget(self, action: #selector(self.refresh), for: .touchUpInside)
Hope this helps.

I suggest to create a xib file and its relevant view for text items that have a button inside it. So you would be able to reuse it elsewhere in the future (this or another projects)
By defining constant height (100) you will experience ugly and misplaced UI in different iOS devices.
Here it is what you should do :
Define a xib file for your custom UITextView
Create constraints for it so it width and height defined by its parent.Also define your forgot UIButton in relative to your UITextView.
Define its (xib) relevant UIView class
Use it in your Storyboard

Answer 3

You can use Storyboard. Make a helper view for the password TextField and Forgot Button.
-Set the Helper view same width and height with the email TextField.
-Add a TextField and a Button inside the helper view and then you can decide for the password TextField width and the Forgot Button width.
-Set constrains for the TextField and Button
I set green color to understand what the helper View does.
Update
I just used your code and it works fine.Check your textfield constrains again. This is what I used.
override func viewDidLoad() {
super.viewDidLoad()
let button = UIButton(type: .system)
button.setTitle("vergessen?", for: .normal)
button.setTitleColor(#colorLiteral(red: 0.3647058904, green: 0.06666667014, blue: 0.9686274529, alpha: 1), for: .normal)
button.frame = CGRect(x: CGFloat(0), y: CGFloat(0), width: CGFloat(100), height: CGFloat(100))
button.addTarget(self, action: #selector(self.refresh), for: .touchUpInside)
textfFeld.rightView = button
textfFeld.rightViewMode = .unlessEditing
}
#objc func refresh(_ sender: Any) {
print("Hello")
}
The only think I changed is the button type from .custom to .system.
