Try this.

 - (IBAction)doneCollectionSaveAction:(id)sender {                
   if([activity isAnimating]==YES){
               [ALToastView toastInView:[UIApplication sharedApplication].keyWindow withText:@"Please wait..."];        
          }else{                
            [self addToCollection];
          }
   }

or


 - (IBAction)doneCollectionSaveAction:(UIButton *)sender {
        if (sender.selected==YES) {
            //do nothing
            [ALToastView toastInView:[UIApplication sharedApplication].keyWindow withText:@"Please wait..."];
        }else{  
                //send data to server
                self.buttonDoneOutlet.selected=YES;
                [self addToCollection];
        }
    }
    //and self.buttonDoneOutlet.selected=NO; //failure network call

When user pressed submit button, show progress hud or an activity Indicator View (loading overlay). This will let user know that some processing is going on and make them not trigger any other action.

Also set synchronous property to that object from which you are calling this WebService. (When you execute something synchronously, you wait for it to finish before moving on to another task. When you execute something asynchronously, you can move on to another task before it finishes.)

And when you got response, clear all data from your form or your app. Because If data is cleared, then user can't insert same record into Database.

So, No need to disable that submit button.

when web service triggers first time.... set button.selected = yes and in function check if button isSelected then not perform action. Use this bool value to distinguish between both conditions.
