UITableView's subview not showing

Question

I have a UITableViewController subclass. When I try to add a subView its not showing.

The subView is a UIImageView, I made a custom loading view (its shown when user is loading data from web).

But when I add,

[self.tableView addSubview:spinner];
[spinner startAnimating];

The spinner is not showing. What am I missing or I did wrong?

EDIT

Code of spinner

UIImageView *spinner = [[UIImageView alloc]init];
spinner.animationImages = [NSArray arrayWithObjects:
                          [UIImage imageNamed:@"spin8.png"],
                          [UIImage imageNamed:@"spin7.png"],
                          [UIImage imageNamed:@"spin6.png"],
                          [UIImage imageNamed:@"spin5.png"],
                          [UIImage imageNamed:@"spin4.png"],
                          [UIImage imageNamed:@"spin3.png"],
                          [UIImage imageNamed:@"spin2.png"],
                          [UIImage imageNamed:@"spin1.png"],
                          nil];

Try implementing this in your code http://stackoverflow.com/questions/20837787/add-a-uirefreshcontrol-below-a-uitableview/20838552#20838552 — iDeveloper, Jan 23 '14 at 04:37
I don't think thats the problem. Because I used same code in other subclasses UIViewController. Its not showing in the subclasses of UITableViewController. Can't understand what's the problem. — Rashad, Jan 23 '14 at 04:51
@Rashad - try with [self.tableView bringSubviewToFront: spiner]; — iPatel, Jan 23 '14 at 04:56

Use MBProgress HUD Its an custom control through which you can easily add various type of Loading indicator

MBProgressHUD *hud = [MBProgressHUD showHUDAddedTo:self.view animated:YES];
hud.mode = MBProgressHUDModeAnnularDeterminate;
hud.labelText = @"Loading";
[self doSomethingInBackgroundWithProgressCallback:^(float progress) {
hud.progress = progress;
} completionCallback:^{
[hud hide:YES];
}];

Use above code or there are lot of other options as well

Try adding it to the tableView's contentView:

[self.tableVew.contentView addSubview:spinner];

Try this

CGRect spinnerFrame = //frame of spinner
UIImageView *spinner = [[UIImageView alloc] initWithFrame:spinnerFrame];
spinner.animationImages = [NSArray arrayWithObjects:
                      [UIImage imageNamed:@"spin8.png"],
                      [UIImage imageNamed:@"spin7.png"],
                      [UIImage imageNamed:@"spin6.png"],
                      [UIImage imageNamed:@"spin5.png"],
                      [UIImage imageNamed:@"spin4.png"],
                      [UIImage imageNamed:@"spin3.png"],
                      [UIImage imageNamed:@"spin2.png"],
                      [UIImage imageNamed:@"spin1.png"],
                      nil];

[self.tableView addSubview:spinner];
[spinner startAnimating];

>> Your solution worked but can you tell the reason why it didn't work in tableView subclass? It is working fine in viewController subclass. – Rashad Jan 23 '14 at 06:24
in viewController subclass, you used `initWithImage:` or `init`.? Because setting the image property does not change the size of a UIImageView, but `initWithImage:` does see [here](https://developer.apple.com/library/ios/documentation/uikit/reference/UIImageView_Class/Reference/Reference.html#jumpTo_9). And are you sure not setting any frame to `UIImageView` in viewController subclass.? – Akhilrajtr Jan 23 '14 at 08:57
Yes I am sure. In my viewController i used "spinner = [[UIImageView alloc]init];" – Rashad Jan 23 '14 at 09:38
