QUESTION
Making a download page in APP, and there are over 10 UIProgressView in the UITableView. The progress bars work fine, but once they are scrolled outside the screen and scrolled back, they update once, then they refuse to update more though they are still downloading.
Here is the code (clear some other code for a clean look):
...ANSWER
Answered 2018-Jun-11 at 14:57I created a sample app a few years ago that demonstrates this exact technique. It is not perfect:

My guess is that you're not correctly modeling the progress of each download. It is important to keep the modeling of that data (and any async requests) separate from the rendering of the table view cells because iOS will set up and tear down each cell as it scrolls off screen. You may also have some threading issues going on, as well.
I would brush up on the UITableViewCell
life cycle events and ensure that you fully understand what's happening when a cell scrolls off screen.
QUESTION
I have a ListTile (in the drawer), which when clicked, goes to a new screen and in that screen the user can choose from a number of (using a for loop) IconButtons (which are in a ListView), but the function which is to be executed when one taps the button is actually executed when the user is sent to the choosing screen (when he/she clicked the ListTile) and as a result the function (which by the way opens another screen) gets executed the same amount of times as there are IconButtons in my ListView and before they are clicked.
For more details see the sourcecode:
When the ListTile is clicked:

that is executed when the button is pressed
QUESTION
I have 2 questions about backgroundWorker: one is cancellation and another is invoking.
My code briefly looks like this:
...ANSWER
Answered 2017-Oct-06 at 17:30There are 2 issues here:
Regarding cancellation - you need to check for cancellation status in the loop that does downloading (thus downloading only part of requested files), not in the later loop which I don't really understand.
As an additional side note you can avoid using BackgroundWorker by using WebClient.DownloadFileAsync
and WebClient.CancelAsync
combo.
As of reporting progress - make you BackgroundWorker
report progress back to the UI thread via ReportProgress
and update UI from there.
