iOS：自定义按钮不在故事板上显示

Question

我在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）。我正在尝试通过Interface Builder直接在故事板中的相同视图上添加自定义按钮。该按钮只是在应用程序运行时不显示。只有图像。你能告诉我在故事板视图上做到这一点的方式吗？或者我应该以编程方式添加它？或者在界面构建器中重做所有100％的东西？真的不知道如何混合和匹配这2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]; 
}

其bcoz你在按钮的顶部添加ImageView的，您可以在使用此代码带到前面，把它放在viewdidload方法：

[self.view bringSubviewToFront:yourBtn];
