rightBarButtonItem显示在所有模拟器上但未在物理iPhone5设备上显示

Question

我创建了以下rightBarButtonItem动画心形图标。它在模拟器设备，Iphone SE，8-plus，X上显示。但是当我连接到我的iPhone5物理设备时，它根本没有显示。

在模拟器iPhoneX上显示

rightBarButtonItem fav图标

在iPhone 5物理设备上，它已丢失，但带有后退按钮的leftBarButtonItem在所有设备上均正常。

我已尝试过代码的选项1和选项2但仍然相同，在物理设备iPhone5上缺失

- (void)viewDidAppear:(BOOL)animated {
    [super viewDidAppear:animated];

    UIButton *heart = [UIButton buttonWithType:UIButtonTypeCustom];
    if ([sURL rangeOfString:@"true"].length > 0){
        [heart setImage:[UIImage imageNamed:@"favorite30px.png"] forState:UIControlStateNormal];
    }else{
        [heart setImage:[UIImage imageNamed:@"notFavorite30px.png"] forState:UIControlStateNormal];
    }

    [heart addTarget:self action:@selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
    heart.imageEdgeInsets = UIEdgeInsetsMake(11.0, 0.0, -11.0, 0.0);

    //--- Option 1
    UIBarButtonItem *jobsButton = [[UIBarButtonItem alloc] initWithCustomView:heart];
    self.navigationItem.rightBarButtonItem = jobsButton;

    //--- Option 2
    // self.btnFav = [[UIBarButtonItem alloc] initWithCustomView:heart];

    // self.navigationItem.rightBarButtonItem = self.btnFav;
}
