Question

好的，这就是正在发生的事情。如果我点击我所拥有的5个段中的段“0”（最右边，因为ios中的segmentcontrol从右边算起0），第一次通过正确的段，即“0”。但是我第二次点击它，它认为我点击了第3段？！这很奇怪！有人可以帮我吗？这是我的代码：

        if ([[_segmentControlTableFunctions.subviews objectAtIndex:2]isSelected] )
    {
        [[_segmentControlTableFunctions.subviews objectAtIndex:2] setTintColor:newSelectedTintColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:1] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:3] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:4] setTintColor:originalColor];

        [self removeAllTables];
        [self displayTables:[Globals sharedInstance].StartUp.Tables];
        self.tableManagement.scrollEnabled = YES;

    }else if ([[_segmentControlTableFunctions.subviews objectAtIndex:3]isSelected] ){

        [[_segmentControlTableFunctions.subviews objectAtIndex:3] setTintColor:newSelectedTintColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:1] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:2] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:4] setTintColor:originalColor];

        [self removeAllTables];
        [self displayTables:[Globals sharedInstance].StartUp.Tables];

    }else if ([[_segmentControlTableFunctions.subviews objectAtIndex:4]isSelected] ){

        [[_segmentControlTableFunctions.subviews objectAtIndex:4] setTintColor:newSelectedTintColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:1] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:2] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:3] setTintColor:originalColor];

        [self removeAllTables];
        [self displayTables:[Globals sharedInstance].StartUp.Tables];
        self.tableManagement.scrollEnabled = YES;

    }else if ([[_segmentControlTableFunctions.subviews objectAtIndex:1]isSelected] ){

        self.currentTable = @"-1";
        _firstTableForCombine = @"-1";
        _nextTable = @"-1";
        _splitTable = @"-1";
        _lastsegmentIndex = -1;
        _segmentOneClicked = false;
        _segmentTwoClicked = false;
        _segmentZeroClicked = false;

        [self.SplitForm removeFromSuperview];
        [self.roundFrameForSplit removeFromSuperview];
        [self.moveOrderToA removeFromSuperview];
        [self.moveOrderToB removeFromSuperview];


        [[_segmentControlTableFunctions.subviews objectAtIndex:4] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:1] setTintColor:newSelectedTintColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:2] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:3] setTintColor:originalColor];

        wait((int*)1000);
        [self removeAllTables];
        [self displayTables:[Globals sharedInstance].StartUp.Tables];
        _segmentControlTableFunctions.selectedSegmentIndex = UISegmentedControlNoSegment;

        [NSTimer scheduledTimerWithTimeInterval: 0.2
                                         target: self
                                       selector: @selector (changeToOriginalColor)
                                       userInfo: nil
                                        repeats: NO];
        self.tableManagement.scrollEnabled = YES;
    }else if ([[_segmentControlTableFunctions.subviews objectAtIndex:0]isSelected] ){
        [[_segmentControlTableFunctions.subviews objectAtIndex:0] setTintColor:originalColor];
        if(_segmentControlTableFunctions.selectedSegmentIndex == 0 && _segmentZeroClicked)
        {
            [self Normal];
        }else
        {
            [self magnify];
        }
    }

编辑代码：

        //This handles all the background color of the segment control when the user clicks on
    //one of the functions.
    if (_segmentControlTableFunctions.selectedSegmentIndex == 2 )
    {
        [[_segmentControlTableFunctions.subviews objectAtIndex:2] setTintColor:newSelectedTintColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:1] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:3] setTintColor:originalColor];
        [[_segmentControlTableFunctions.subviews objectAtIndex:4] setTintColor:originalColor];

        [self removeAllTables];
        [self displayTables:[Globals sharedInstance].StartUp.Tables];
        self.tableManagement.scrollEnabled = YES;

    }else if (_segmentControlTableFunctions.selectedSegmentIndex == 1 ){

Answer 1

子视图不是静态的。我怀疑当你选择一个标签时，视图层次结构会发生变化（添加光泽，移动东西或其他东西），索引不再是你怀疑的。有人评论说，首先选择所选的段索引。我强烈建议切换到使用选定的段索引，而不是基于子视图中的索引。从所选索引返回的值始终是正确的。

Answer 2

tintColor属性仅用于更改整个控件的色调。如果要更改所选段的颜色与未选择的段，则应使用setBackgroundImage：forState：barMetrics：而不是。如果这是您想要的外观，您将需要创建一个彩色图像。它可以这样做（sc是分段控件的出口）：

- (void)viewDidLoad {
    [super viewDidLoad];
    UIImage *selectedImage = [UIImage imageNamed:@"GreenColor.png"];
    UIImage *unselectedImage = [UIImage imageNamed:@"GrayColor.png"];
    [self.sc setBackgroundImage:selectedImage forState:UIControlStateSelected barMetrics:UIBarMetricsDefault];
    [self.sc setBackgroundImage:unselectedImage forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
}

对于那些想知道的人来说，这对我有用。：）

                for (int i = 0; i < self.segmentControlTableFunctions.subviews.count; i++)
            {
                if ([[self.segmentControlTableFunctions.subviews objectAtIndex:i]isSelected] )
                {
                    [[self.segmentControlTableFunctions.subviews objectAtIndex:i] setTintColor:newSelectedTintColor];
                }
                else
                {
                    [[self.segmentControlTableFunctions.subviews objectAtIndex:i] setTintColor:originalColor];
                }
            }
