Add GracePeriod Option

[benmarten]

I would like to see an option for setting a grace period. I have subclassed JGProgressHUD for one of my projects. Maybe you want to implement something similar?

import "JGProgressHUD.h"

@interface FSProgressHUD : JGProgressHUD

@Property NSNumber* graceTime;
@Property BOOL taskInProgress;
@Property BOOL showInSuperview;

• (void)showInView:(UIView*)view;
• (void)dismiss;

@EnD

import "FSProgressHUD.h"

@interface FSProgressHUD ()

@Property NSTimer* graceTimer;
@Property UIView* view;

@EnD

@implementation FSProgressHUD

/**
Shows the HUD animated. You should preferably show the HUD in a UIViewController's view.
@param view The view to show the HUD in. The frame of the @c view will be used to calculate the position of the HUD.
*/

• (void)showInView:(UIView*)view
  {
  if (_graceTime && [_graceTime doubleValue] > 0.0) {
  _view = view;
  _taskInProgress = YES;
  _graceTimer = [NSTimer scheduledTimerWithTimeInterval:[_graceTime doubleValue] target:self
  selector:@selector(handleGraceTimer:)
  userInfo:nil
  repeats:NO];
  }
  else {
  [super showInView:view];
  }
  }
• (void)dismiss
  {
  _taskInProgress = NO;
  [super dismiss];
  }
• (void)handleGraceTimer:(NSTimer*)theTimer
  {
  if (_taskInProgress) {
  if (_showInSuperview && _view.superview) {
  [super showInView:_view.superview];
  }
  else {
  [super showInView:_view];
  }
  }
  }

This is unnecessary, a simple dispatch_after call can take care of this.
