如何在iOS 11的导航栏上设置大标题?

以下是用于在iOS 11或更高版本的导航栏左侧显示大标题的代码片段。

目标C:

  self.title = @"Your title";
    if (@available(iOS 11, *)) {
        self.navigationController.navigationBar.prefersLargeTitles = true;
         self.navigationController.navigationItem.largeTitleDisplayMode = UINavigationItemLargeTitleDisplayModeAlways;
    }

       self.title = "Your title"
        if #available(iOS 11, *) {
            self.navigationController?.navigationBar.prefersLargeTitles = true
            self.navigationController?.navigationItem.largeTitleDisplayMode = .always
        } 

在构建应用程序之前,需要为iOS 11设置检查条件。

测试大标题的要求:

• Mac OSX-10.12.6或更高版本,

if (@available(iOS 11.0, *)) {
    [[UINavigationBar appearance] setPrefersLargeTitles:false];
}

您可以设置 UILabel标签 进入 .

UILabel *lblTitle = [[UILabel alloc] init];
lblTitle.text = YOUR_TITLE_TEXT;
lblTitle.backgroundColor = [UIColor clearColor];
lblTitle.textColor = [UIColor whiteColor];
lblTitle.font = FONT_NAV_BAR;
[lblTitle sizeToFit];
self.navigationItem.titleView = lblTitle;
