[英]How to set the font size of navigation bar title
I try to set the fontsize of my navigation title and other items. 我尝试设置导航标题和其他项目的fontsize。 How can I do this ?
我怎样才能做到这一点 ?
There are a lot of answers mentoining that we just can set this with the method uinavigationbar.setTitleTextAttributes, but this method doesn't exist (anymore) 我们可以使用uinavigationbar.setTitleTextAttributes方法设置此方法,但是这个方法不存在(不再存在)
Does someone know how to do ? 有人知道该怎么办吗?
navigationBar = UINavigationBar(frame: CGRectMake(0, 0, fDialogWidth, navbarHeigth))
let navigationItem = UINavigationItem()
navigationItem.title = sTitle;
// Create left and right button for navigation item
let leftButton = UIBarButtonItem(title: sBacklabel, style: UIBarButtonItemStyle.Plain, target: self, action: "backAction:")
let rightButton = UIBarButtonItem(title: saddBookmark, style: UIBarButtonItemStyle.Plain, target: self, action: "addBookmarkAction:")
// Create two buttons for the navigation item
navigationItem.leftBarButtonItem = leftButton
navigationItem.rightBarButtonItem = rightButton
navigationBar.items = [navigationItem];
navigationBar.frame = CGRectMake(0, 0, screenwidth, navbarHeigth);
Add these lines to your viewDidLoad()
method: 将这些行添加到
viewDidLoad()
方法:
self.navigationController?.navigationBar.topItem?.title = "Your title"
self.navigationController?.navigationBar.titleTextAttributes = [ NSFontAttributeName: UIFont(name: "Your Font", size: 34)!, NSForegroundColorAttributeName: UIColor.whiteColor()]
try this... 尝试这个...
let titleAttributes = [
NSFontAttributeName: UIFont(name: "your font name", size: 15)!
]
self.navigationController?.navigationBar.titleTextAttributes = titleAttributes
If you are using system font then 如果您正在使用系统字体
let titleAttributes = [
NSFontAttributeName: UIFont.systemFontOfSize(15)
]
self.navigationController?.navigationBar.titleTextAttributes = titleAttributes
Update for swift 4 更新swift 4
Presumably you want to set the tittle for UINavigationbar with system fontsize 30 and yellow color. 大概你想用系统fontsize 30和黄色设置UINavigationbar的tittle。 The syntax would probably look like the followings:
语法可能如下所示:
navigationItem.title = "Your Title"
navigationController?.navigationBar.titleTextAttributes = [NSAttributedStringKey.font: UIFont.systemFont(ofSize: 30),NSAttributedStringKey.foregroundColor: UIColor.yellow]
