帮我！

我的代码如下：

if([SegmentRound selectedSegmentIndex] == 0)    {        UIcolor *newSelectedTintcolor2 = [UIcolor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:0] setTintcolor:newSelectedTintcolor2];        UIcolor *newSelectedTintcolor1 = [UIcolor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:1] setTintcolor:newSelectedTintcolor1];        UIcolor *newSelectedTintcolor0 = [UIcolor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:2] setTintcolor:newSelectedTintcolor0];        FLAGROUND=1;    }    if([SegmentRound selectedSegmentIndex] == 1)    {        UIcolor *newSelectedTintcolor1 = [UIcolor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:1] setTintcolor:newSelectedTintcolor1];        UIcolor *newSelectedTintcolor0 = [UIcolor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:0] setTintcolor:newSelectedTintcolor0];        UIcolor *newSelectedTintcolor2 = [UIcolor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:2] setTintcolor:newSelectedTintcolor2];        FLAGROUND=2;    }    if([SegmentRound selectedSegmentIndex] == 2)    {        UIcolor *newSelectedTintcolor0 = [UIcolor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:2] setTintcolor:newSelectedTintcolor0];        UIcolor *newSelectedTintcolor2 = [UIcolor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:0] setTintcolor:newSelectedTintcolor2];        UIcolor *newSelectedTintcolor1 = [UIcolor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 Alpha:1.0];        [[[SegmentRound subvIEws] objectAtIndex:1] setTintcolor:newSelectedTintcolor1];        FLAGROUND=3;    }

vIEwWillAppear中：

[SegmentRound setSelectedSegmentIndex:0];

解决方法 我建议在你的条件之外创建两种颜色,使你的代码变小.然后,您可以使用foreach迭代您的细分：

UIcolor *selectedcolor = [UIcolor colorWithRed: 98/255.0 green:156/255.0 blue:247/255.0 Alpha:1.0];UIcolor *deselectedcolor = [UIcolor colorWithRed: 54/255.0 green:52/255.0 blue:48/255.0 Alpha:1.0];for (UIControl *subvIEw in [SegmentRound subvIEws]) {    if ([subvIEw isSelected])        [subvIEw setTintcolor:selectedcolor];     else       [subvIEw setTintcolor:deselectedcolor]; }
