Question

我正在我的故事板中以编程方式显示图像并成功处理横向/纵向（请参阅下面的代码）。我现在正尝试通过Interface Builder直接在故事板中的同一视图上添加自定义按钮。应用程序运行时，该按钮不会显示。只有图像。你能告诉我在故事板视图上做到这一点的方法吗？或者我应该以编程方式添加它吗？或者在Interface builder中重做100％的所有内容？真的不知道如何混合和匹配这两种方法...

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.
    [[self navigationController] setNavigationBarHidden:YES animated:YES];



    UIImage *startImage = [UIImage imageNamed:@"title.png"];
    UIImageView *startImageView = [[UIImageView alloc] initWithImage:startImage];

    self.startImageView = startImageView;

    [self.view addSubview:startImageView];


}

- (void) orientStartImageView
{
     UIInterfaceOrientation curOrientation = [UIApplication sharedApplication].statusBarOrientation;
     if (curOrientation == UIInterfaceOrientationPortrait || curOrientation == UIInterfaceOrientationPortraitUpsideDown) {
     [self.startImageView setFrame:CGRectMake(-128, 0, 1024, 1024)];
 }else{
     [self.startImageView setFrame:CGRectMake(0, -128, 1024, 1024)];
 }
}

- (void) viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [self orientStartImageView];
}

- (void)viewWillLayoutSubviews
{
    [super viewWillLayoutSubviews];
    [self orientStartImageView];
}

它的bcoz你正在Button上添加ImageView，你可以使用这段代码把它带到前面，把它放在viewdidload方法中：

[self.view bringSubviewToFront:yourBtn];

iOS：自定义按钮未显示在Storyboard上
