iphone - 如何将 UIActivityIndi​​catorView 添加到 UITableViewCell？

Question

我想将 UIActivityIndi​​cator 添加到 UITableViewCell。我能怎么做？

Answer 1

试试这样

UITableViewCell *cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:@"NoReuse"] autorelease];
cell.textLabel.text = @"Loading...";

UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc] 
    initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleGray] autorelease];

// Spacer is a 1x1 transparent png
UIImage *spacer = [UIImage imageNamed:@"spacer"];

UIGraphicsBeginImageContext(spinner.frame.size);

[spacer drawInRect:CGRectMake(0,0,spinner.frame.size.width,spinner.frame.size.height)];
UIImage* resizedSpacer = UIGraphicsGetImageFromCurrentImageContext();

UIGraphicsEndImageContext();
cell.imageView.image = resizedSpacer;
[cell.imageView addSubview:spinner];
[spinner startAnimating];

return cell;

Answer 2

UIActivityIndicatorView *spinner = [[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite] autorelease];
spinner.frame = CGRectMake(205.0f, 0.0f, 44.0f, 44.0f);
spinner.tag = 3;
[cell.contentView addSubview:spinner];
