Question

Is it possible to add a UIActivityIndicatorView to the left side of a UITableViewCell? We're already using the right side of a UITableViewCell for a disclosure indicator.

Thanks.

Answer 1

Sure. Just instantiate a UIActivityIndicatorView, give it a .frame that sets it where you want it, add it as a subview of cell.contentView, and call startAnimating .

UIActivityIndicatorView *spinner = [[UIActivityIndicatorView alloc] 
    initWithFrame:CGRectMake(0,0,20,20)]; //or whatever--this will put it in the top left corner of the cell
[cell.contentView addSubview:spinner]
[spinner startAnimating];
[spinner release];

Answer 2

If you create a custom cell, you can do anything you want. But this document here from Apple should give you all you need whether just adding subviews to a regular old UITableViewCell or creating your own.
