swift bold title in navigation bar

Question

installed fonts for title navigation bar

UINavigationBar.appearance().titleTextAttributes = [.font: UIFont(name: "OpenSans", size:50 )!,NSAttributedString.Key.foregroundColor : UIColor.purple]

how do I make it bold ?

found, that can be done so, but after all the fine print I already set

.font : UIFont.boldSystemFont(ofSize: 50)

Answer 1

您必须说要使用的字体命名为 OpenSans ，其样式为粗体

"OpenSans-Bold"

所以使用这个：

.font: UIFont(name: "OpenSans-Bold", size: 50)!

Answer 2

您应该使用Open Sans的粗体。代替“ OpenSans”，使用与粗体版本ex对应的字​​符串。 “ OpenSans-Bold”

UINavigationBar.appearance().titleTextAttributes = [.font: UIFont(name: "OpenSans-Bold", size:50 )!,NSAttributedString.Key.foregroundColor : UIColor.purple]

字体名称将特定于您的环境。
