UIBarButtonSystemItem信息与统计

Question

我需要两个我找不到的按钮:信息按钮和UINavigationBar的Stats按钮。有没有一种方法可以在不画按钮的情况下找到表示类似事物的按钮？

Answer 1

希望这能帮到你：

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

对于统计，没有这样的默认按钮可用

Answer 2

迅速3/4

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