我使用下面的代码来更改 UISegmentedcontrol 中每个分段的文本颜色，如何更改特定分段的文本颜色？（例如索引 2 处的分段）

for (id seg in [segment subviews]) 
     for (id label in [seg subviews]) 
        if ([label isKindOfClass:[UILabel class]])
                [label setTextColor:[UIColor redColor]];

I use below code for change textcolor of each segmented in UISegmentedcontrol how can I change textcolor of specific segment?(for example segment at index 2)

for (id seg in [segment subviews]) 
     for (id label in [seg subviews]) 
        if ([label isKindOfClass:[UILabel class]])
                [label setTextColor:[UIColor redColor]];

我使用下面的代码来解决这个问题

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]];
                    [label setTextColor:[UIColor colorWithRed:0.888 green:0.888 blue:0.888 alpha:1]];   
                }//if
        }//else
        eg++;
    }//for

i use below code for this problem

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]];
                    [label setTextColor:[UIColor colorWithRed:0.888 green:0.888 blue:0.888 alpha:1]];   
                }//if
        }//else
        eg++;
    }//for

据我所知，目前还没有基于定制的解决方案。但是您可以将图像用于必要的片段 (setImage:forSegmentAtIndex:) 或查看以下内容：
