根據UISegmentedControll的狀態更改UILegmentedControll中的UILabel文本

Question

有什麼方法可以使用UIAppearance來更改UISegmented Controller中選定段的文本顏色，並讓其他段具有相同的顏色？

Answer 1

NSDictionary *attributesDictionary = [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 systemFontOfSize:14],             UITextAttributeFont, 
              nil]; 
[[UISegmentedControl appearance] setTitleTextAttributes:attributesDictionary forState:UIControlStateSelected];
