Inside application, on click button start screen goes in background with floating buttons and it start recording screen, I wanna to rotate screen manually from floating button which was in background. rotate screen over all application.
I have checked react-native-orientation and react-native-orientation-locker npm modules which works only on particular application screen rotation.

Yes, it is possible to rotate your view based on your requirements. but for this, I think you have to manage it yourself.
You can achieve to by using the transform API.

How to create animated splash screen not with Images in iOS

I want to know that how one should proceed in building animated splash screen.
I already did the animated splash screen with images but here I want to add custom animation like something is drawn on screen etc.
can anyone guide me through this.
simply you need to present a UIViewController which is hold your animations and dismiss it when your app is ready to launch. but also I think its better to follow apple HIG .. as apple describe you should
Supply a launch image to improve user experience.
Avoid using your launch image as an opportunity to provide:
An “application entry experience,” such as a splash screen An About
window Branding elements, unless they are a static part of your
application’s first screen Because users are likely to switch among
applications frequently, you should make every effort to cut launch
time to a minimum, and you should design a launch image that downplays
the experience rather than drawing attention to it.
Generally, design a launch image that is identical to the first screen
of the application.
Exceptions:
Text. The launch image is static, so any text you display in it will
not be localized.
UI elements that might change. Avoid including elements that might
look different when the application finishes launching, so that users
don’t experience a flash between the launch image and the first
application screen.

How can I differ between manual and automatic scrolling in NSScrollView/NSTextView

I subclassed NSTextView and added support for automatic scrolling in a userdefineable time.
Now I want to detect, if the user manually scrolls, while the view is scrolling automatically.
Then I want to immediately stop automatic scrolling, until the user stops his action and then I want to start scrolling again from the new position.
I want to do this in such a matter, that the user can move around without a stuttering view.
I use boundsDidChangeNotification to calculate the scrolling position (playtime) and show it in a label, but I can't use it to detect the user manual scrolling, because it is also pushed by the automatic scrolling...
Would be very nice, if anyone has an idea ;-)
Thanks in advance

Draw on/directly above desktop?

Is there a way to force a window directly above the desktop and make it transparent? Basically I want a way to draw an image and animation on the desktop so that it integrates (ie. a clock that sits on your desktop, below other windows, has a transparent background, etc).
Also, if you have a solution, is it an official API?
Use an NSWindow initialised with style NSBorderlessWindowMask and make it floating
setLevel:NSFloatingWindowLevel
You can place your view hierarchy into that window.
