UIActivityIndicator scrolls with tableView

问题

I have a table view controller .When I start activity indicator to animate and then scroll the table view , activity indicator starts to scroll with that . I have tried to set a specific location for activity indicator and also add it as subview of vew .This is the codes that I have written for that :

spinner.frame.origin.x = self.view.frame.size.width / 2  - (spinner.frame.size.width / 2)
spinner.frame.origin.y = self.view.frame.size.height  - (self.tableView.rowHeight / 2 )
spinner.hidesWhenStopped = true
self.view.addSubview(spinner)

What's wrong with that ?

Thanks in advance

回答1:

When you are using a UITableViewController then self.view is the table (the same as self.tableView). You are adding the spinner to the table so when the table scrolls, the spinner scrolls too.

To avoid this, don't use a UITableViewController. Use a simple UIViewController and add a UITableView to it. Then self.view won't scroll.

something like

self.tableView.backgroundView = indicator;

might help
