问题描述
iOS中UIBarItem中的setTitleTextAttributes:forState:如何使用?
你如何设置NSDictionary?无法使其工作，文档对此也不是很清楚.
How do you set the NSDictionary? Can't make it work and documentation isn't very clear about that.
来自文档:
setTitleTextAttributes:forState:
为给定的控件状态设置标题的文本属性:
- (void)setTitleTextAttributes:(NSDictionary *)attributes
forState:(UIControlState)state
参数:
attributes:包含文本属性键值对的字典.您可以使用 NSString UIKit Additions Reference 中列出的键指定字体、文本颜色、文本阴影颜色和文本阴影偏移量.
attributes: A dictionary containing key-value pairs for text attributes. You can specify the font, text color, text shadow color, and text shadow offset using the keys listed in NSString UIKit Additions Reference.
state:要为其设置标题文本属性的控件状态.
state: The control state for which you want to set the text attributes for the title.
