I'm having problems getting MEVFloatingButton to work, probably due to my view setup. I have a parent view controller that adds a childviewcontroller like so:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; OverviewGridController *mainView = [storyboard instantiateViewControllerWithIdentifier:@"OverviewGridController"];
[self addChildViewController:mainView]; [self.view addSubview:mainView.view]; [mainView didMoveToParentViewController:self];

The child view controller has a collectionview on which I want to place the floating button.

I have tried to add it from the parent like this:

UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil]; OverviewGridController *mainView = [storyboard instantiateViewControllerWithIdentifier:@"OverviewGridController"];
MEVFloatingButton *button = [[MEVFloatingButton alloc] init]; button.animationType = MEVFloatingButtonAnimationNone; button.displayMode = MEVFloatingButtonDisplayModeWhenScrolling; button.position = MEVFloatingButtonPositionBottomRight; button.image = [UIImage imageNamed:@"icon_aplus"]; button.imageColor = [UIColor colorWithRed:44/255.0f green:62/255.0f blue:80/255.0f alpha:1]; button.backgroundColor = [UIColor colorWithRed:65/255.0f green:131/255.0f blue:215/255.0f alpha:1]; button.outlineColor = [UIColor colorWithRed:44/255.0f green:62/255.0f blue:80/255.0f alpha:1]; button.outlineWidth = 3.0f; button.imagePadding = 20.0f; button.horizontalOffset = -30.0f; button.verticalOffset = -30.0f; button.rounded = YES; button.shadowColor = [UIColor lightGrayColor]; button.shadowOffset = CGSizeMake(3, 3); button.shadowOpacity = 0.6f; button.shadowRadius = 3.0f;

[mainView setFloatingButtonView:button]; [mainView setFloatingButtonDelegate:self];

[self addChildViewController:mainView]; [self.view addSubview:mainView.view]; [mainView didMoveToParentViewController:self];

Button is not added and delegate methods are not responding.

I have also tried to add it in the child in it's viewdidload. Button is not added BUT when setting button.displayMode = MEVFloatingButtonDisplayModeWhenScrolling (and only then) the floatingButtonDidDisappear delegate method is triggered when the view is loaded.

Would really appreciate if someone can point me in the right direction.

Hi,

I want to give rotation animation into MEVFloatingButton. So I tried with this,

- (void)floatingButton:(UIScrollView *)scrollView didTapButton:(UIButton *)button {
    [UIView animateWithDuration:0.2 delay:0 options:UIViewAnimationOptionCurveLinear animations:^{
        [self.button setTransform:CGAffineTransformRotate(self.button.transform, M_PI)];
    }completion:^(BOOL finished){
        NSLog(@"completed animating");
    }];
}

On a standard UIButton, it will rotate its button with button's center. But with MEVFloatingButton, it rotated like a mars with sun as it center. I mean, MEVFloatingButton is the mars.

Is there any solution? Thank you!

I am using the button to trigger a UIImagePickerController to appear. After selecting or capturing an image, the modal is removed from the view, but the button has been as well. Simply setting button.hidden = false brings the button back, but it's annoying behavior to have to call that every time you return to the view controller containing the button.

Steps to replicate:

• Add button to tableView
• Present a UIImagePickerController
• Dismiss UIImagePickerController

I added the project according to provided steps but it is continuously crashing when it reaches to try section of mev_dealloc method. Can you check the same please cause even your sample app crashes over there. I tried even commenting the method call location, but still the app runs but the button doesn't appears at all.

I want to implement the example2 project in my app. Please suggest me the solution.

Is there any step that I am missing out of it? IS it necessary to install the pod in order to run add this in my project?

Hi, Once keyboard appeared and the keyboard will overlay the MEVFloatingButton. Normally, i think it could be following the keyboard moving up. Thanks
