Question

我有一个分段控制器，现在并在分段1上点击一个视图，然后在第二个分段上点击另一个视图，就在这个分段控制器的下方。现在我希望当出现这个分段控制器的视图出现时，第一个分段控制器视图随之出现，并且第一个分段控制器按钮似乎预先被分接。

我能够通过这种方式展示我的观点来完成这件事。但是我做了不必要的事情......请以其他方式告诉我。

-(void)loadTest
 {
if(!cabinInfoDetailsViewObj)
{
    cabinInfoDetailsViewObj = [[CabinInfoDetailsView alloc]initWithFrame:CGRectMake(232, 188, 617,412)];
}

[self addSubview:cabinInfoDetailsViewObj];

[CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_WhiteButton.png"] forSegmentAtIndex:0];
[CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_GreyButton.png"] forSegmentAtIndex:1];

}

这是段控制器部分

- (IBAction)CabinInfoSegmentButtonTapped:(id)sender
{
if(CabinInfoPopupSegmentControl.selectedSegmentIndex == 0)
{

    if(!cabinInfoDetailsViewObj)
    {
        cabinInfoDetailsViewObj = [[CabinInfoDetailsView alloc]initWithFrame:CGRectMake(232, 188, 617,412)];
    }
    [CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_WhiteButton.png"] forSegmentAtIndex:0];
    [CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_GreyButton.png"] forSegmentAtIndex:1];
    cabinInfoDetails.textColor = [UIColor blueColor];
    cabinInfoLocate.textColor =[UIColor blackColor];

    [cabinInfoDeckPlansViewObj removeFromSuperview];
    [self addSubview:cabinInfoDetailsViewObj];

}
if(CabinInfoPopupSegmentControl.selectedSegmentIndex == 1)
{
    if(!cabinInfoDeckPlansViewObj)
    {
        cabinInfoDeckPlansViewObj = [[CabinInfoDeckPlansView alloc]initWithFrame:CGRectMake(232, 188, 617,412)];
    }

    [CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_WhiteButton.png"] forSegmentAtIndex:1];
    [CabinInfoPopupSegmentControl setImage:[UIImage imageNamed:@"16.4_GreyButton.png"] forSegmentAtIndex:0];

    cabinInfoDetails.textColor = [UIColor blackColor];
    cabinInfoLocate.textColor =[UIColor blueColor];

    [cabinInfoDetailsViewObj removeFromSuperview];
    [self addSubview:cabinInfoDeckPlansViewObj];

}

在我的应用程序中，使用了以下代码：

//Give .h file UISegmentedControl  *seg;


- void)viewDidLoad
{

 seg        = [[UISegmentedControl alloc] initWithItems:[NSArray arrayWithObjects:@"Notification", @"Messages", nil]];
seg.tag                         = 1;
seg.segmentedControlStyle       = UISegmentedControlStyleBar;
seg.frame                       = CGRectMake(1, 0, 318, 45);
[seg addTarget:self action:@selector(segmentAction:) forControlEvents:UIControlEventValueChanged];
seg.tintColor                   = [UIColor whiteColor];
seg.selectedSegmentIndex        = 0;
seg.backgroundColor=[UIColor clearColor];
[seg setDividerImage:[UIImage imageNamed:@""] forLeftSegmentState:UIControlStateNormal rightSegmentState:UIControlStateNormal barMetrics:UIBarMetricsDefault];
[seg setImage:[UIImage imageNamed:@"notificationselected.png"] forSegmentAtIndex:0];
[seg setImage:[UIImage imageNamed:@"message.png"] forSegmentAtIndex:1];
[self.view addSubview:seg];

}

pragma mark - UISegmentedControl
- (IBAction)segmentAction:(id)sender
{
UISegmentedControl *segControll = (UISegmentedControl *)sender;
if (segControll.selectedSegmentIndex==0)
{
    [segControll setImage:[UIImage imageNamed:@"notificationselected.png"] forSegmentAtIndex:0];
    [segControll setImage:[UIImage imageNamed:@"message.png"] forSegmentAtIndex:1];

 //right code for select the segmentcontroll.index=0
}
else if (segControll.selectedSegmentIndex==1)
{
    [segControll setImage:[UIImage imageNamed:@"notification.png"] forSegmentAtIndex:0];
    [segControll setImage:[UIImage imageNamed:@"messageselected.png"] forSegmentAtIndex:1];

    //right code for select the segmentcontroll.index=1
  }
}

我希望它会对你有所帮助。
