ios - 为 Bar button item 添加 Bg 和 tint color

我以编程方式创建了一个条形按钮项。现在它看起来是简单的文本。我需要设置无边框的背景颜色，还需要以编程方式设置色调颜色。这是我创建一个条形按钮项目的代码:

UIBarButtonItem *callBtn = [[UIBarButtonItem alloc] initWithTitle:@"Call Me" style:UIBarButtonItemStylePlain target:self action:@selector(signUpButtonTapped:)];
    self.navigationItem.rightBarButtonItem = callBtn;

背景颜色应该是:#F9F9F9

色调颜色应为:00ACC1

使用自定义按钮进行自定义控制以下代码可能会有所帮助

 UIButton *button = [UIButton buttonWithType:UIButtonTypeSystem];
button.frame = CGRectMake(0,0,60,30);
[button setBackgroundColor:[UIColor yourColor]];
[button setTitleColor:[UIColor yourColor] forState:UIControlStateNormal];
[button setTitle:@"Call Me" forState:UIControlStateNormal];
[button addTarget:self action:@selector(navigateToDiscussionScreen) forControlEvents:UIControlEventTouchUpInside];

UIView *view = [[UIView alloc] initWithFrame:button.bounds];
view.backgroundColor = [UIColor clearColor];
[view addSubview:button];
UIBarButtonItem *logoBtn = [[UIBarButtonItem alloc]initWithCustomView:view];
