uitextfield

问题 I am trying to create a UITextField that will always display the blinking cursor whether the keyboard is displaying or not. Is there any way I can achieve this effect? 回答1: @andreamazz answer in Swift. UITextField show cursor even when userInteractionEnabled is set to NO UIView.animateWithDuration(1, delay: 0, options: .Repeat, animations: {() -> Void in cursorView.alpha = 0 }, completion: {(animated: Bool) -> Void in cursorView.alpha = 1 }) 来源： https://stackoverflow.com/questions/39059625

问题 Why doesn't the shouldChangeCharactersInRange update the textfield right away. It is 1 delayed by one character. For example, download this file: https://www.dropbox.com/s/goljs3d6lcxutxy/UITextField%20Tutorial.zip?dl=0 add the following code to func textField(textField: UITextField, shouldChangeCharactersInRange range: NSRange, replacementString string: String) -> Bool { method print(textField.text) see how it is delayed by one character. I want it to be updated as I type the text not one

问题 so i make this otp screen but i have some catch, i make this otp screen with bunch of uitextfield and i make the logic of it, but i just cant delete on of the num in the textfield that i make the textfield wont delete when i fill like the first 2 of my num, even i pressess backButton it wont work.....but it will work when i fill the whole num of textfield, in my case is six. so i have to fill all six of the number and i can delete the number from the textfield, it wont work if only half fill

问题 I have an app that works properly on iOS 11-13, but when I run it in iOS 14 several text fields within it are rendered with a nil, and so transparent, background color even though the background color is set to White explicitly in the Interface Builder. I can't see anywhere in the code that uses those text fields that might mess up the background color, and these same UITextFields running under the same scenarios appear with White background on iOS 13 and below. If I set the color explicitly
