如何在文本字段和键盘中隐藏蓝色光标？

Question

I need to get an empty textfield when my ViewController Appears. I tried this:

override func viewWillAppear(animated: Bool) {
    linkField.placeholder = "test"
    linkField.text = ""
}

But when it appears the keyboard pops up and a blue cursor blinks in a textField. How can I get rid of those ?

EDIT:

I think I didn't explain my question correctly. I don't need to get an empty cursor, I just need to hide it and the keyboard until user touches the textfield to input something.

Answer 1

The textfield cursor color is based on the default tint color. In your case it's blue. I would change the tint color to clear color.

linkField.tintColor = UIColor.clearColor()

For the edited question, if you just want to dismiss the keyboard then

linkField.resignFirstResponder()

will dismiss the keyboard and when you want focus again use

linkField.becomeFirstResponder()

Answer 2

Create subclass of UITextField and override caretRectForPosition

import UIKit

class RemoveBlinkCursor: UITextField {
    override init(frame:CGRect)
    {
        super.init(frame:frame)
    }

    required init(coder aDecoder: NSCoder) {
        super.init(coder: aDecoder)
    }

    override func caretRectForPosition(position: UITextPosition!) -> CGRect {
        return CGRectZero
    }
}

After your edit answer changed :

For show and hide keyboard and focus you can use resign and become first responders as said by Vig.

Hope this will help to others for removing blinking bar.

Answer 3

try this

self.textField.tintColor = [UIColor clearColor];

Hope it helps.

Swift 3 Xcode 8

Calling view.endEditing(true) has always worked for me
