在iOS状态栏中显示下载进度

Question

I would like to display the download progress in the iOS status bar the same way android does. I know we can show the activity indicator but I was thinking

Answer 1

You cannot display download progress in the iOS status bar. The iOS Human Interface Guidelines for Progress Indicators shows some alternatives: https://developer.apple.com/ios/human-interface-guidelines/controls/progress-indicators/

A brief summary of the options:

1. Display a spinner using a UIActivityIndicatorView .
2. Display a progress bar with UIProgressView .
3. Show the network activity indicator in the status bar.

You can also roll your own implementations of the spinner or progress bar, or use one of many third-party frameworks.

Hope that helps!
