如何在Mac OSX上获取和设置目标c中的壁纸？

#import <Foundation/Foundation.h>
#import <AppKit/AppKit.h>

int main(int argc, const char * argv[]) {
    @autoreleasepool {
        // 获取壁纸
        NSString *wallpaperPath = @"/Library/Desktop Pictures/";
        NSFileManager *fileManager = [NSFileManager defaultManager];
        NSArray *wallpapers = [fileManager contentsOfDirectoryAtPath:wallpaperPath error:nil];
        
        // 输出壁纸列表
        NSLog(@"Wallpapers:");
        for (NSString *wallpaper in wallpapers) {
            NSLog(@"%@", wallpaper);
        }
        
        // 设置壁纸
        NSURL *wallpaperURL = [NSURL fileURLWithPath:[wallpaperPath stringByAppendingPathComponent:@"YourWallpaper.jpg"]];
        NSArray *screens = [NSScreen screens];
        NSWorkspace *workspace = [NSWorkspace sharedWorkspace];
        
        for (NSScreen *screen in screens) {
            NSError *error = nil;
            [workspace setDesktopImageURL:wallpaperURL forScreen:screen options:@{} error:&error];
            
            if (error) {
                NSLog(@"Failed to set wallpaper for screen %@: %@", screen, error);
            } else {
                NSLog(@"Wallpaper set successfully for screen %@", screen);
            }
        }
    }
    return 0;
}
