Does iOS voice input option is available with "Number Keypad" in the applications as I observed that "Voice input" option disappears when we select number keypad for textfield or search bar.

Xcode 10 - Launch storyboard with static images

Currently I'm using static launch images to be able to show a full-screen image on app startup, which can show a different image: one designed for portrait and one for landscape. The only way I've been able to do this is to NOT use storyboards.

However, I want my app to run on a new iPad Pro with no letterboxing, so it looks like I'll have to use a launch storyboard. But I'm afraid I won't be able to implement the adaptive launch images I have set up....

So it is possible, even practical, to use full-screen, orientation-dependent images within a launch storyboard?
Divide string into components separated by , but keep strings in ""
I would like to divide a line such as:
```
1,abc,"def ghi",jk
```
into array of Strings separated by commas while keeping strings in "" as single elements of array, even if this string contains a comma.

For example:
```
1,"abc,def",ghi
```
should become:
```
["1", "abc,def", "ghi"]
```
What would be the best approach to this? It should be as fast as possible, as it will be executed over large files.

Swift problem with the table view inside a tableView cell

I need you help because I don't know what I did wrong... Here is my problem:

I created a custom table view inside a tableView cell and when I launch my application the innerTableView doesn't show.

How can set video as a home screen and lock screen in ios Objective-C

I have a local video and set the home screen and lock screen also, but just not see it?

So basically you have a video in my iPhone application.

Is this possible if so how?
Input detection for the cpu

When we write a code and provide an input through the keyboard to the system then when we press a certain alphabet the bits corresponding to the ASCII values should be being transferred at back-end and in case of numbers the binary form of number related bits must be being transferred. How does the system detect whether the bits it has received for a input is an ASCII value related bit or a simple number when we are providing input and if there is a certain mechanism for this in CPU then how does the compiler decide which form of input bits it has received and print out type mismatch when we provide different type of input in terminal? Please clarify the whole mechanism.
Detect if touch keyboard is active

I am trying to do an action every time the touch keyboard is being opened or closed. But I have trouble detecting these event. WinSpy doesn't seem to detect it, and TabTip.exe always is running.
Owl Carousel keyboard navigation with multiple carousel

Is there a way to fix keyboard tabbing with the left and right keys when multiple owl carousels are on a page?

The issue is although the keyboard tabbing works - also it affects all the owl carousels on the page instead of the one focused on. So all the owl carousels and moving.

Is it because of this function. Is there a more specific way of calling just the current owl carousel instead of: document.documentElement

Here's the demo: https://codepen.io/anon/pen/YRQZVK
More than four keyboard inputs?

I have made a simple top-down shooter that isn't very good but still fun to boot up whenever we have some time off. It started out with just two players on one keyboard and that worked fine. However, now I have made it so that three players can play on the same keyboard and then we had a small problem - the keyboard inputs. I have tried four different approaches (two of them using p5.js built-in systems, and two using normal keydown and keyup events). With three of them it worked quite well although if four keys were pressed the game wouldn't detect any more inputs. With the last approach (keydown and keyup) everything worked fine except for the fact that when someone held down a button no other input would update, not keydown neither keyup.

And for those of you who didn't want to read all that. What is the best way to handle keyboard input if it at some points could need to manage nine different inputs at once?

I am still pretty new to JavaScript so please bear with me. Also if this doesn't happen to anyone else it might not be the input handling that's wrong but I think it is! Thanks!

simulate ctrl+c event in windows 10 using python

I am trying to simulate ctrl+c keyboard event in the python3 using the library pyautogui. Unfortunately, the library doesn't generate this event. Is there any other way to generate this?

The following code is not working,

from pyautogui import hotkey

hotkey('ctrl', 'c')

I want to do this task for the following code. The code can record live audio for the arbitrary duration and the recording can stop anytime by pressing 'Ctrl+c'. I want to generate this event so that I can add some additional features.

import os
import sys
import time
import queue
import soundfile as f
import sounddevice as sd

def callback(indata, frames, time, status):
            """
    This function is called for each audio block from the record function.
    """

    if status:
        print(status, file=sys.stderr)
    q.put(indata.copy())

def record(filename):

    try:
        # Make sure the file is open before recording begins
        with sf.SoundFile(filename, mode='x', samplerate=48000, channels=2, subtype="PCM_16") as file:
            with sd.InputStream(samplerate=48000, channels=2, callback=callback):
                print('START')
                print('#' * 80)
                """ 
                Here is the place I want to generate the event (Ctrl+c) 
                after n minutes
                """
                print('press Ctrl+c to stop the recording')
                while True:
                    file.write(q.get())
    except KeyboardInterrupt:
        print('The recording is over.')

if __name__ == "__main__":
    q = queue.Queue()
    record('filename.wav')

Same key with different effects in glutKeyboardFunc

I'm making a game from a rpg gamebook using C and OpenGL. I want to know if I can use the same key with different efects, eg, pressing changes what is shown in the screen, but in other context, inside the same calling of glutKeyboard it would select some option given.

Can you set contentInset more than once?

I have a tableview with table cells. Each cell has a textfield. I have the following code to prevent the bottom few cells from being blocked by the keyboard

@objc func keyboardWillShow(_ notification:Notification) {
    if let keyboardSize = (notification.userInfo?[UIResponder.keyboardFrameEndUserInfoKey] as? NSValue)?.cgRectValue {
        tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardSize.height, right: 0)
    }
}
@objc func keyboardWillHide(notification: NSNotification) {
    tableView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
}
override func viewDidLoad() {
    super.viewDidLoad()

    NotificationCenter.default.addObserver(self, selector: #selector(TransactionViewController.keyboardWillHide), name: UIApplication.keyboardWillChangeFrameNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(TransactionViewController.keyboardWillShow), name: UIApplication.keyboardWillChangeFrameNotification, object: nil)
}

The keyboardWillHide function works as expected. However, when the keyboard is hidden, the table does bounce back down the the bottom, resulting in no extra whitespace being shown (which is what I want). What I don't like is how you can still scroll down on the table to the contentInset from where the keyboard was first shown. Is there a way to make it so that after the keyboard disappears, that you can't scroll down passed the bottom of the table?

How to set keyboardAppearance and inputView?.backgroundColor to dark at the same time?

I have datePicker that I set as inputView of textField.

import UIKit

class ViewController: UIViewController {

    @IBOutlet weak var textField: UITextField!
    var datePicker: UIDatePicker = UIDatePicker()

    override func viewDidLoad() {
        super.viewDidLoad()

        datePicker.datePickerMode = .date
        datePicker.setValue(UIColor.white, forKeyPath: "textColor")
        textField.inputView = datePicker

        textField.keyboardAppearance = .dark
        textField.inputView?.backgroundColor = #colorLiteral(red: 0.07627698034, green: 0.1097967997, blue: 0.1355849206, alpha: 1)
    }

}

I want to have dark toolbar and dark UIDatePicker's background at the same time. But, actually, textField.inputView?.backgroundColor doesn't work.

But if I comment textField.keyboardAppearance = .dark, the background of datepicker changes:
