Question

我正在尝试实施一个下拉菜单并找到了这个：iOSPullDownMenu

我按照描述完成了将下拉菜单添加到我的一个视图中。但是，每当我使用下拉菜单进入页面时，应用程序都会退出

[PulldownMenu setTranslatesAutoresizingMaskIntoConstraints：]：看不到实例的无法识别的选择器。

我不知道如何解决这个问题，我们将不胜感激。

这是我的代码：

- (void)viewDidLoad
{
    [super viewDidLoad];

    pulldownMenu = [[PulldownMenu alloc] initWithView:self.view];
    [self.view addSubview:pulldownMenu];

    [pulldownMenu insertButton:@"Menu Item 1"];
    [pulldownMenu insertButton:@"Menu Item 2"];
    [pulldownMenu insertButton:@"Menu Item 3"];

    pulldownMenu.delegate = self;
    [pulldownMenu loadMenu];

    [[self navigationController] setNavigationBarHidden:YES animated:YES];

    self.view.backgroundColor = [UIColor colorWithPatternImage:[UIImage
                                                    imageNamed:@"login_bg.png"]];

    CGRect frame1 = CGRectMake(20, 20, 100.0, 100.0);
    self.button1 = [UIButton buttonWithType:UIButtonTypeSystem];
    self.button1.frame = frame1;
    self.button1.layer.cornerRadius = 10;
    self.button1.clipsToBounds = YES;
    [self.button1 addTarget:self action:@selector(btn1Pressed:)
                       forControlEvents:UIControlEventTouchUpInside];
    [self.view addSubview:self.button1];
}

-(IBAction)menuTap:(id)sender
{
    [pulldownMenu animateDropDown];
}

这是错误：

 -[PulldownMenu setTranslatesAutoresizingMaskIntoConstraints:]: unrecognized selector sent to instance 0x9177360
