Answer 1

In didSelectRowAtIndexPath method you could make a call to below function:-

-(void)setActivityIndcator:(UIView *)view
{
  transparentView = [[UIView alloc] init];
  transparentView.frame = view.frame;  //Provide frame of right side view.
  transparentView.alpha = 0.5;   //To provide transparent look and feel.

  activityInd = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];

  activityInd.frame = CGRectMake(transparentView.frame.size.width/2, transparentView.frame.size.height/2, 50, 50);  //Change as you want it to be

  [transparentView addSubview:activityInd];

  [activityInd startAnimating];

  [self performSelector:@selector(stopIndicator) withObject:self afterDelay:1];
}

-(void)stopIndicator  //This method will be called after delay and would remove view and activityInd
{
  [activityInd stopAnimating];

  [activityInd removeFromSuperview];
  [transparentView removeFromSuperview];
}

Also you could create a subclass of it and use it in any viewcontroller by creating it's object. That why u don't need to write down all function everytime.

Answer 2

Use the delegate method didSelectRowAtIndexPath of TableView and write the following code into it

UIActivityIndicatorView *activity = 
[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
activity.frame = CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/2, 50, 50);
[self.view addSubview:activity];
[activity startAnimating];

Stope this when your work is done and remove it from the view

Answer 3

use this in this method didSelectRowAtIndexPath

UIActivityIndicatorView *activityView = 
[[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhite];
activityView.frame = CGRectMake(120, 230, 50, 50);
[self.view addSubview:activityView];
