你怎么用setTitleTextAttributes:forState:in ？UIBarItemiOS

你是怎么设置的NSDictionary？无法使其工作，文档对此也不是很清楚。

从文档中：

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：包含文本属性的键值对的字典。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。

state：您要为其设置标题的文本属性的控件状态。

示例代码：

[[UIBarItem appearance] setTitleTextAttributes:
[NSDictionary dictionaryWithObjectsAndKeys:
[UIColor colorWithRed:220.0/255.0 green:104.0/255.0 blue:1.0/255.0 alpha:1.0], UITextAttributeTextColor, 
[UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0], UITextAttributeTextShadowColor, 
[NSValue valueWithUIOffset:UIOffsetMake(0, 1)], UITextAttributeTextShadowOffset, 
[UIFont fontWithName:@"AmericanTypewriter" size:0.0], UITextAttributeFont, nil] 
forState:UIControlStateNormal];

斯威夫特 5.0：

// Bar title text color
let shadow = NSShadow()
shadow.shadowColor = UIColor(red: 1.0, green: 1.0, blue: 1.0, alpha: 1.0)
shadow.shadowOffset = CGSize(width: 0, height: 1)
let color : UIColor = UIColor(red: 220.0/255.0, green: 104.0/255.0, blue: 1.0/255.0, alpha: 1.0)
let titleFont : UIFont = UIFont(name: "AmericanTypewriter", size: 16.0)!

let attributes = [
    NSAttributedString.Key.foregroundColor : color,
    NSAttributedString.Key.shadow : shadow,
    NSAttributedString.Key.font : titleFont
]
self.navigationItem.rightBarButtonItem?.setTitleTextAttributes(attributes, for: .normal)

// Or you can use
UIBarItem.appearance().setTitleTextAttributes(attributes, for: .normal)

这是 phix23 的代码，只是更新了，我认为更简洁的语法：

[[UIBarItem appearance] setTitleTextAttributes:@{
                      UITextAttributeTextColor: [UIColor colorWithRed:220.0/255.0 green:104.0/255.0 blue:1.0/255.0 alpha:1.0],
                UITextAttributeTextShadowColor: [UIColor colorWithRed:1.0 green:1.0 blue:1.0 alpha:1.0],
               UITextAttributeTextShadowOffset: [NSValue valueWithUIOffset:UIOffsetMake(0, 1)],
                           UITextAttributeFont: [UIFont fontWithName:@"AmericanTypewriter" size:0.0]}
                                      forState: UIControlStateNormal];

Swift5设置UIBarItem标题颜色

let attributes = [
    NSAttributedString.Key.foregroundColor : UIColor.orange,
    NSAttributedString.Key.font : UIFont.systemFont(ofSize: 20)
]
vc.tabBarItem.setTitleTextAttributes(attributes, for: .normal)
