What i would do is add a touchable overlay behind your popup.

In your .h

@interface YourController : UIViewController{
    UIView *overlay;
}

in your view did load

overlay = [[UIView alloc] initWithFrame:self.view.frame];
overlay.bakcgroundColor = [UIColor clearColor];
UITapGestureRecognizer *singleFingerTap = 
[[UITapGestureRecognizer alloc] initWithTarget:self 
                                      action:@selector(handleSingleTap)];
[overlay addGestureRecognizer:singleFingerTap];

And then your methods would look like :

- (void) showPopView
{
   [self.view addSubview:overlay];
   self.popview.alpha = 1;
   [self.popview setFrame:CGRectMake(15, 100, 300, 300)];
   //[self dismissPopoverAnimated:NO];
}

- (void)handleSingleTap{
    [overlay removeFromSuperview];
    self.popview.alpha = 0;
    [self.popview setFrame:CGRectZero];
}

In background of pop up view add custom button(UIButton) to hide the popup. As it is custom button user can see the background view. Make sure button should occupy whole screen. Also when u show the pop view show the button and when user hide the pop view hide the button also so that user can get access to all area. This is the most simplest way. Other options are there like Tap gesture or check for the touches but custom button in background can minimize the risk.

I did created a demo using UIButton and it's working ,check below-

- (void)viewDidLoad
{
 [super viewDidLoad];
 backgroundButton = [[UIButton alloc] initWithFrame:CGRectMake(0,0,self.view.frame.size.width,self.view.frame.size.height)];

 [backgroundButton addTarget:self action:@selector(tapDetected) forControlEvents:UIControlEventTouchUpInside];
}

-(void)tapDetected
{
 [backgroundButton removeFromSuperview];
 [tempView removeFromSuperview];
}

-(void)showPopup /* on button click I created popup view as you already had */
{
  [self.view addSubview:backgroundButton]; //Adding button to self.view

 tempView = [[UIView alloc] initWithFrame:CGRectMake(15, 100, 300, 300)];
 [tempView setBackgroundColor:[UIColor redColor]];

 [backgroundButton addSubview:tempView];  //Adding popup view to button.
 [tempView setAlpha:1];
}
