{code:title=CDVSplashScreen.m|borderStyle=solid}

// line 99
UIView* parentView = self.viewController.view;
    parentView.userInteractionEnabled = NO;  // disable user interaction while splashscreen is shown
    _activityView = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:topActivityIndicatorStyle];
    //_activityView.center = CGPointMake(parentView.bounds.size.width / 2, parentView.bounds.size.height / 2);
    //_activityView.autoresizingMask = UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleBottomMargin | UIViewAutoresizingFlexibleRightMargin;
    [_activityView startAnimating];

    // Set the frame & image later.
    _imageView = [[UIImageView alloc] init];
    [parentView addSubview:_imageView];

    id showSplashScreenSpinnerValue = [self.commandDelegate.settings objectForKey:[@"ShowSplashScreenSpinner" lowercaseString]];
    // backwards compatibility - if key is missing, default to true
    if ((showSplashScreenSpinnerValue == nil) || [showSplashScreenSpinnerValue boolValue])
    {
        [_activityView setTranslatesAutoresizingMaskIntoConstraints:FALSE];
        [parentView setTranslatesAutoresizingMaskIntoConstraints:FALSE];
        [parentView addSubview:_activityView];
        NSLayoutConstraint* constraintX = [NSLayoutConstraint constraintWithItem:_activityView attribute:NSLayoutAttributeCenterX relatedBy:NSLayoutRelationEqual toItem:parentView attribute:NSLayoutAttributeCenterX multiplier:1 constant:0];
        NSLayoutConstraint* constraintY = [NSLayoutConstraint constraintWithItem:_activityView attribute:NSLayoutAttributeCenterY relatedBy:NSLayoutRelationEqual toItem:parentView attribute:NSLayoutAttributeCenterY multiplier:1 constant:0];
        [parentView addConstraint:constraintX];

>             Project: Apache Cordova
>          Issue Type: Bug
>          Components: Plugin SplashScreen
>    Affects Versions: 4.0.1
>            Reporter: Gabriel Fringeli
>              Labels: easyfix
>   Original Estimate: 5m
>  Remaining Estimate: 5m
>
> On iOS devices the current plugin version does not center the activity view (Spinner) in its parent view. Instead its center is bound to the upper left corner. Only after some time (5 seconds) the activity view is centered in its parent view.
> I already have fixed this bug by replacing the current positioning (via _activityView.center and _activityView.autoresizingMaks) with NSLayoutConstraint.
