The issue you're facing is likely due to the fact that the code you described is running on the main thread, which is also responsible for updating the UI. When you use a time delay, as in your case, it blocks the main thread, preventing the UI updates from occurring until the delay is complete. To achieve the desired behavior of changing the background colors of buttons one at a time with a one-second delay in between, you should use a separate thread or queue to handle the time delays. In iOS, you can use Grand Central Dispatch (GCD) or an asynchronous task to perform the background color changes without blocking the main thread. Here's a simplified example in Swift:
DispatchQueue.global().async {
for button in buttonsArray {
usleep(1000000) // Sleep for 1 second (in microseconds)
DispatchQueue.main.async {
button.backgroundColor = // New background color
}
}
}
This code runs the background color change on a separate thread, ensuring that the UI updates happen one at a time with a one-second delay in between, without freezing the main thread. The same concept can be adapted to Pythonista or your specific programming environment.
