macOS开发NSMenu NSMenuItem的简单是使用-鼠标右键菜单栏

鸣谢：哈尔滨的酸柠檬

先睹为快

#import "ViewController.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

}

#pragma mark 获取鼠标右键事件
-(void)rightMouseDown:(NSEvent *)event{

    //创建Menu
    NSMenu *theMenu = [[NSMenu alloc] initWithTitle:@"Contextual Menu"];
    //NSMenu *theMenu = [[NSMenu alloc] init];
    
    //常规添加菜单
    [theMenu insertItemWithTitle:@"Item 1"action:@selector(beep:)keyEquivalent:@""atIndex:0];

    [theMenu insertItemWithTitle:@"Item 2"action:@selector(beep:)keyEquivalent:@""atIndex:1];
    
    //自定义的NSMenuItem
    NSMenuItem *item3 = [[NSMenuItem alloc]init];

    item3.title = @"Item 38";

    item3.target = self;

    item3.action = @selector(beep:);

    [theMenu insertItem:item3 atIndex:2];

    [NSMenu popUpContextMenu:theMenu withEvent:event forView:self.view];

}

#pragma mark 统一使用响应方法，不然不使用该方法的菜单栏将不能点击
-(void)beep:(NSMenuItem *)menuItem{

    NSLog(@"_____%@", menuItem);

}


#pragma mark 暂时不清楚这是干什么的
- (void)setRepresentedObject:(id)representedObject {

    [super setRepresentedObject:representedObject];

    // Update the view, if already loaded.

}

@end
