UIBarButtonSystemItem信息和统计

Question

我需要两个按钮，我无法找到：信息按钮和统计按钮UINavigationBar。有没有办法找到代表类似事物的按钮而不绘制它们？

Answer 1

希望这有助于你：

//for info button using custom UIButton 
    UIButton *btn = [UIButton buttonWithType:UIButtonTypeInfoDark]; 
    self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithCustomView:btn]; 

统计没有这样的默认按钮可用

let infoButton = UIButton(type: .infoDark) 
infoButton.addTarget(self, action: #selector(navbarButtonPressed), for: .touchUpInside) 
navigationItem.rightBarButtonItems?.append(UIBarButtonItem(customView: infoButton))
