CarouselPage Xamarin

Recently I made a carouselpage in Xamarinforms, Android works perfectly, but in iOS it seems to be a bit loose, and have a balloon effect vertically, and the carouselpage should only be horizontal. I discovered that when the NavigationPage.SetHasNavigationBar (this, true); this is true with the carousel does not have this bug, but with false happens, does anyone know how I fix this problem?
