在macOS上模拟鼠标滚轮(swift或objc)

import Cocoa

func simulateMouseScroll() {
    let eventSource = CGEventSource(stateID: .hidSystemState)
    let scrollEvent = CGEvent(scrollWheelEvent2Source: eventSource, units: .pixel, wheelCount: 1, wheel1: 0, wheel2: 10, wheel3: 0)
    scrollEvent?.post(tap: .cghidEventTap)
}

simulateMouseScroll()

#import <Cocoa/Cocoa.h>

void simulateMouseScroll() {
    CGEventSourceRef eventSource = CGEventSourceCreate(kCGEventSourceStateHIDSystemState);
    CGEventRef scrollEvent = CGEventCreateScrollWheelEvent(eventSource, kCGScrollEventUnitPixel, 1, 10, 0);
    CGEventPost(kCGHIDEventTap, scrollEvent);
    CFRelease(scrollEvent);
    CFRelease(eventSource);
}

simulateMouseScroll();
