在导航栏中创建副标题

Create a subtitle in navigationbar

在 iOS 中,您可以创建标题:

self.navBar.title = @"";

我在 header 文件中设置导航栏的位置。

还有副标题/描述吗?

当我在 self.navBar 后面输入 . 时,我发现了 description,我想也许我可以用这个做点什么?

使用self.navBar.navigationItem.prompt = @"This is the subtitle";

它来自基础 UINavigationViewController 中的 UIKit。

Objective-C

代码
UILable *title = [[UILabel alloc]init];
UILabel *subtitle = [[UILabel alloc]init];

[title setFont:[UIFont systemFontOfSize:12]];
[title setTextColor:[UIColor whiteColor]];
[title setFont:[UIFont systemFontOfSize:17]];
[title sizeToFit];
title.text = @"Title";

[subtitle setTextColor:[UIColor whiteColor]];
[subtitle setFont:[UIFont systemFontOfSize:12]];
[subtitle setTextAlignment:NSTextAlignmentCenter];
[subtitle sizeToFit];
subtitle.text = @"Subtitle Title";

UIStackView *stackVw = [[UIStackView alloc]initWithArrangedSubviews:@[title,subtitle]];
stackVw.distribution = UIStackViewDistributionEqualCentering;
stackVw.axis = UILayoutConstraintAxisVertical;
stackVw.alignment =UIStackViewAlignmentCenter;


[stackVw setFrame:CGRectMake(0, 0, MAX(title.frame.size.width, subtitle.frame.size.width), 35)];
self.navigationItem.titleView = stackVw;
