Use iOS 8 default blur view

// -- add blur effect
    UIBlurEffect *blurEffect = [UIBlurEffect effectWithStyle:UIBlurEffectStyleLight];
    
    UIVisualEffectView *blurEffectView = [[UIVisualEffectView alloc] initWithEffect:blurEffect];
    
    [blurEffectView setFrame:self.view.bounds];
    
    
    [self.view addSubview:blurEffectView];

    //[self.view insertSubview:blurEffectView atIndex:0];

UIImagePickerController has iPad issue in iOS 8 : Attempt to present on which is already presenting (null)

I think this is because in iOS 8, alert views and action sheets are actually presented view controllers (UIAlertController). So, if you're presenting a new view controller in response to an action from the UIAlertView, it's being presented while the UIAlertController is being dismissed. I worked around this by delaying the presentation of the UIImagePickerController until the next iteration of the runloop, by doing this:

[[NSOperationQueue mainQueue] addOperationWithBlock:^{
    // just add picker code here and it will work fine.
}];

Image Popup in popover view : small popup in UIView

    if([popoverVC isPopoverVisible])
    {
        //close the popover view if toolbar button was touched
        //again and popover is already visible
        //Thanks to @chrisonhismac
        
        [popoverVC dismissPopoverAnimated:YES];
        return;
    }
    
    //build our custom popover view
    UIViewController* popoverContent = [[UIViewController alloc] init];
    
    UIView* popoverView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 250, 250)];
    
    popoverView.backgroundColor = [UIColor whiteColor];
    
    popoverContent.view = popoverView;

    popoverVC = [[UIPopoverController alloc] initWithContentViewController:popoverContent];
    
    popoverVC.contentViewController.preferredContentSize =  CGSizeMake(250, 250);
    
    [popoverVC presentPopoverFromRect:sender.frame   // did you forget to call this method?
