我用下面的代码对于这个问题

int eg=0; 
    for (id seg in [sg subviews]) 
    { 
     int gg=sg.selectedSegmentIndex; 
     if(gg==2) 
      gg=0; 
     else if(gg==0) 
      gg=2; 
     if(eg==gg && eg!=1) 
     { 
      for (id label in [seg subviews]) 
       if ([label isKindOfClass:[UILabel class]]) 
       { 
        [label setTextAlignment:UITextAlignmentCenter]; 
        [label setFont:[UIFont boldSystemFontOfSize:12]]; 
        [label setTextColor:[UIColor colorWithRed:0.325 green:0.565 blue:0.788 alpha:1]]; 
       }//if 
     }//if 
     else if(eg==1) 
     { 
      for (id label in [seg subviews]) 
       if ([label isKindOfClass:[UILabel class]]) 
       { 
        [label setTextAlignment:UITextAlignmentCenter]; 
        [label setFont:[UIFont boldSystemFontOfSize:11]]; 
        [label setTextColor:[UIColor grayColor]]; 
       }//if 
     }//else if 
     else 
     { 
      for (id label in [seg subviews]) 
       if ([label isKindOfClass:[UILabel class]]) 
       { 
        [label setTextAlignment:UITextAlignmentCenter]; 
        [label setFont:[UIFont boldSystemFontOfSize:11]];

改变文本颜色特定段的？据我知道有没有基于定制的解决方案。但是，您可以使用必要细分的图片（setImage:forSegmentAtIndex:）或看看这个： http://matteocaldari.it/2010/05/a-uisegmentedcontrol-with-custom-color（作者已将子类别UISegmentedControl &实施了自定义绘图覆盖drawRect:方法）。
