I've been developing a programming where the user can select a list of fields from popup buttons, then they press a calculate button and then depending on the choices, a string of text gets outputted to a UIText Field.
However I would like for the text field to be cleared when the user starts selecting other choices in the popup button before pressing the select button.
Is there anyway this is possible?
Just right this code in the place where that happens:
/*You can replace theTextFieldYouAreTalkingAbout with the one you are talking about*/
theTextFieldYouAreTalkingAbout.text = ""
I have a table view list and an add button at the top right. The user would press the button and a text field would pop up for a user to enter a string to be the label of the new item. Nothing new or special, what you'd expect from a "new playlist" type situation.
I am looking to have the small text field input that the user would type into. Most examples have the app move to a new view controller with a text field. I simply want a little box to overlay the current view that accepts a string. I cannot find/remember the name of the text box so I cannot find examples or code.
I think you are searching for something like
https://github.com/bmancini55/iOSExamples-DockedKeyboardView
Where your UITextField would be attached on the keyboard's accessory view.
OR
http://nshipster.com/uialertcontroller/
Where you use an UIALertController with an input field. I think the second one will resolve your problem more than the first one, because you are asking for a pop-up solution.
Hope it helps
Is there a native UI control for code input text field, for example like Whatsapp:
No. To achieve this, they're almost certainly tapping into the textField:shouldChangeCharactersInRange:replacementString: method for their UITextField, selectively accepting and formatting user input to match the dash-if-empty approach.
Further, I'm sure they've subclassed the field; per your comments there isn't a blue cursor - which isn't standard for a UITextField.
No there isn't. Use a UITextField, fill it with dashes, keep track of how many characters the user has entered, and replace the dashes accordingly as the user types.
There's a 4-digit code input text field called CodeInputView written in Swift.
In the past I've added a UITextField to the view and set its hidden == true. Then I show/hide the keyboard by calling becomeFirstResponder()/resignFirstResponder() on it. I listen for text did change notifications and update a visible label with the value of the hidden text field.
Hi! Thanks in advance...
I am doing a code to add a string value in a Vector and show that value on a textfield and after, display that value on the editfield. And I want to make an event for that editfield to update the vector value for the Blackberry I want to make a code.
I make one customeTextField and one button field on clicking this button field the value enter on customeTextField is added to vector and create a new customeTextfield which holds the enter string.
I want to event for the another customeTextField which will update the string and vector element in blackberry.
(Blackberry code is necessary)
Try to get the index of element on the focus listener of the text field then make a code for the fieldchange listener and take the index of element and write the setElement for the vector method.
I am using edit field to enter some text. When I click on edit field, one Highlighting box is showing as in image. I want to hide that box. Please catch the problem using below image:
How to remove this focused box in edit field??
As it's Edit Field, its default nature is to highlight text for editing. If you are going to enter values in the field during application runtime means you have to bare this. If you are going to enter values programatically means use Rich Text Field or your
editfield.setEditable(false);
