Butang UI tidak boleh diklik

Question

Fail dimuat naik ke Github (sangat kecil)

Kelas UIView LeftMenuView ditambahkan pada viewcontroller
Paparan atas dan paparan bawah ditambahkan pada LeftMenuView
Dua butang ini tidak boleh diklik.
userInteractionEnabled ialah YA,
bingkai butang dipaparkan dalam Penyahpepijatan Paparan dan tidak melebihi paparan induk.
Sebahagian daripada kod:
ViewController:

- (void)viewDidLoad {
    [super viewDidLoad];
    LeftMenuView *leftView=[LeftMenuView createLeftMenuView];
    leftView.userInteractionEnabled=YES;
    self.leftView=leftView;
    [self.view addSubview:leftView];
    //nightButton
    UIButton *nightButton=[self.leftView viewWithTag:6];
    [nightButton addTarget:self action:@selector(touchButton:) forControlEvents:UIControlEventTouchUpInside];
    leftView.userInteractionEnabled=YES;
//    [self.leftView addSubview:nightButton];
    //set
    UIButton *settingButton=[self.leftView viewWithTag:4];
    [settingButton addTarget:self.leftView action:@selector(push) forControlEvents:UIControlEventTouchUpInside];
    }
    

LeftMenuView: Ini ialah UIview Nampaknya acara tidak perlu ditambahkan pada paparan, bukan? ? ?
