iphone - 在 UISegmentedControl 的选定选项卡上是否可以使用不同样式的字体？

Question

我已经编写了这段代码来为 UISegmentedControl 的正常状态和突出显示状态设置字体属性，但它不起作用。请帮我指出原因。

NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"Helvetica" size:12.0f], UITextAttributeFont,

                            [UIColor blackColor], UITextAttributeTextColor,

                            nil];

NSDictionary *boldAttributes = [NSDictionary dictionaryWithObjectsAndKeys: [UIFont fontWithName:@"Helvetica-Bold" size:12.0f], UITextAttributeFont,

                            [UIColor blackColor], UITextAttributeTextColor,

                            nil];



[self.tab setTitleTextAttributes:attributes forState:UIControlStateNormal];

[self.tab setTitleTextAttributes:boldAttributes forState:UIControlStateHighlighted];

我希望选定的文本是粗体，否则它应该是正常的。

我试过如下

NSDictionary *attributes = [NSDictionary dictionaryWithObjectsAndKeys:
                        [UIFont boldSystemFontOfSize:17], UITextAttributeFont,
                        [UIColor blackColor], UITextAttributeTextColor,
                        nil];
[_segmentedControl setTitleTextAttributes:attributes forState:UIControlStateNormal];
NSDictionary *highlightedAttributes = [NSDictionary dictionaryWithObject:[UIColor    whiteColor] forKey:UITextAttributeTextColor];
[_segmentedControl setTitleTextAttributes:highlightedAttributes  forState:UIControlStateHighlighted];

并设置字体

 [UIFont fontWithName:@"FontName" size:desiredsize.f]

同时将突出显示更改为选中。
