Macos 如何从AXMenu获取AXMenuItems数组？,macos,cocoa,menu,parent-child,accessibility-api,Macos,Cocoa,Menu,Parent Child,Accessibility Api,对于我的代码，我试图从AXMenu（AXUIElementRef）中获取AXMenuItems数组。菜单成功登录，下面是我的代码： NSArray *anArray = [NSRunningApplication runningApplicationsWithBundleIdentifier:@"com.apple.dock"]; AXUIElementRef anAXDockApp = AXUIElementCreateApplication([[anArray objectAtIndex:0

对于我的代码，我试图从

AXMenu

（

AXUIElementRef

）中获取

AXMenuItems

数组。菜单成功登录，下面是我的代码：

NSArray *anArray = [NSRunningApplication runningApplicationsWithBundleIdentifier:@"com.apple.dock"];
AXUIElementRef anAXDockApp = AXUIElementCreateApplication([[anArray objectAtIndex:0] processIdentifier]);

CFTypeRef aChildren;
AXUIElementCopyAttributeValue(anAXDockApp, kAXChildrenAttribute, &aChildren);

SafeCFRelease(anAXDockApp);

CFTypeRef aMenu = CFArrayGetValueAtIndex(aChildren, 0);

NSLog(@"aMenu: %@", aMenu);

                    // Get menu items
CFTypeRef aMenuChildren;
AXUIElementCopyAttributeValue(aMenu, kAXVisibleChildrenAttribute, &aMenuChildren);

for (NSInteger i = 0; i < CFArrayGetCount(aMenuChildren); i++) {

    AXUIElementRef aMenuItem = [self copyAXUIElementFrom:aMenu role:kAXMenuItemRole atIndex:i];

    NSLog(@"aMenuItem: %@", aMenuItem); // logs (null)

    CFTypeRef aTitle;
    AXUIElementCopyAttributeValue(aMenuItem, kAXTitleAttribute, &aTitle);


    if ([(__bridge NSString *)aTitle isEqualToString:@"New Window"] || [(__bridge NSString *)aTitle isEqualToString:@"New Finder Window"]) /* Crashes here (i can see why)*/{

        AXUIElementPerformAction(aMenuItem, kAXPressAction);

        [NSThread sleepForTimeInterval:1];

        break;

    }

}

NSArray*anArray=[NSRunningApplication runningApplicationsWithBundleIdentifier:@“com.apple.dock”]；
AXUIElementRef anAXDockApp=AXUIElementCreateApplication（[[anArray objectAtIndex:0]processIdentifier]）；
CFTypeRef-aChildren；
AXUIElementCopyAttributeValue（anAXDockApp、kAXChildrenAttribute和aChildren）；
安全释放（anAXDockApp）；

获取AXMenuItems
列表的正确方法是什么
可访问性检查器的屏幕截图：
如何从AXMenu获取AXMENUITEM数组？”问题的答案：aMenuChildren
是菜单项列表。确保您可以按角色kAXMenuItemRole
进行筛选
“为什么它不工作？”问题的答案：菜单不是菜单。当您在AXAccessibility Inspector中检查菜单时，它会显示一条警告“父元素不将元素报告为其子元素之一”。Dock应用程序有一个子项，即Dock项列表。
我已经找到了一个答案，使用AXUIElementCopyElementAtPosition（）
获取菜单的答案。由于存在多个停靠方向和隐藏，我必须在.h文件中创建枚举，因为它比0、1或2更容易读取
// .h
typedef enum {
    kDockPositionBottom,
    kDockPositionLeft,
    kDockPositionRight,
    kDockPositionUnknown
} DockPosition;

typedef enum {
    kDockAutohideOn,
    kDockAutohideOff
} DockAutoHideState;

然后，我在.m

// .m
- (DockPosition)dockPosition
{
    NSRect screenRect = [[NSScreen mainScreen] frame];

    NSRect visibleRect = [[NSScreen mainScreen] visibleFrame];

    // Dont need to remove menubar height
    visibleRect.origin.y = 0;

    if (visibleRect.origin.x > screenRect.origin.x) {
        return kDockPositionLeft;
    } else if (visibleRect.size.width < screenRect.size.width) {
        return kDockPositionRight;
    } else if (visibleRect.size.height < screenRect.size.height) {
        return kDockPositionBottom;
    }
    return kDockPositionUnknown;
}

- (DockAutoHideState)dockHidden
{
    NSString *plistPath = [NSHomeDirectory() stringByAppendingPathComponent:@"Library/Preferences/com.apple.dock.plist"];
    NSDictionary *dockDict = [NSDictionary dictionaryWithContentsOfFile:plistPath];

    CFBooleanRef autohide = CFDictionaryGetValue((__bridge CFDictionaryRef)dockDict, @"autohide");
    if (CFBooleanGetValue(autohide) == true) {
        return kDockAutohideOn;
    }
    return kDockAutohideOff;
}

这个方法[copyAXUIElementFrom:role:atIndex:
是@Willeke中的一个方法回答了我的另一个问题：
- (AXUIElementRef)copyAXUIElementFrom:(AXUIElementRef)theContainer role:(CFStringRef)theRole atIndex:(NSInteger)theIndex {
    AXUIElementRef aResultElement = NULL;
    CFTypeRef aChildren;
    AXError anAXError = AXUIElementCopyAttributeValue(theContainer, kAXChildrenAttribute, &aChildren);
    if (anAXError == kAXErrorSuccess) {
        NSUInteger anIndex = -1;
        for (id anElement in (__bridge NSArray *)aChildren) {
            if (theRole) {
                CFTypeRef aRole;
                anAXError = AXUIElementCopyAttributeValue((__bridge AXUIElementRef)anElement, kAXRoleAttribute, &aRole);
                if (anAXError == kAXErrorSuccess) {
                    if (CFStringCompare(aRole, theRole, 0) == kCFCompareEqualTo)
                        anIndex++;
                    SafeCFRelease(aRole);
                }
            }
            else
