自定义UISegmentedControl，添加背景图片和选定的分段色调颜色

Dublicate this，但它不适合我。自定义UISegmentedControl，添加背景图片和选定的分段色调颜色

我使用UICatalog创建了UISegmentedControl并尝试更改选定的段颜色。我用this来改变颜色。背景图片工作正常，但不会更改选定的段颜色。我应该做些什么修改？或者其他方法相同？我的代码如下。

NSArray *segmentTextContent = @[@"First",@"Second",@"Third"]; 
    UISegmentedControl *segmentedControl = [[UISegmentedControl alloc] initWithItems:segmentTextContent]; 

    segmentedControl.frame = CGRectMake(20, 50, 280, 30); 

    [segmentedControl addTarget:self 
         action:@selector(segmentAction:) 
       forControlEvents:UIControlEventValueChanged]; 

    segmentedControl.segmentedControlStyle = UISegmentedControlStyleBar; 
    segmentedControl.selectedSegmentIndex = 1; 
    segmentedControl.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin; 

    [segmentedControl setBackgroundImage:[UIImage imageNamed:@"navigationBar"] 
           forState:UIControlStateNormal 
           barMetrics:UIBarMetricsDefault]; 

    [segmentedControl setDividerImage:[UIImage imageNamed:@"divider"] 
        forLeftSegmentState:UIControlStateNormal 
        rightSegmentState:UIControlStateNormal 
          barMetrics:UIBarMetricsDefault]; 

    // we want attributed strings for this segmented control 
    NSDictionary *textAttributes = @{ UITextAttributeTextColor:[UIColor whiteColor], 
UITextAttributeFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:13] }; 
    [segmentedControl setTitleTextAttributes:textAttributes forState:UIControlStateNormal]; 

    textAttributes = @{ UITextAttributeTextColor:[UIColor whiteColor], 
UITextAttributeFont:[UIFont fontWithName:@"HelveticaNeue-Bold" size:13] }; 
    [segmentedControl setTitleTextAttributes:textAttributes forState:UIControlStateHighlighted]; 

    [self.view addSubview:segmentedControl]; 

- (void)segmentAction:(UISegmentedControl *)sender 
{ 
    for (int i=0; i<[sender.subviews count]; i++) { 
     if ([[sender.subviews objectAtIndex:i]isSelected]) { 
      UIColor *tintcolor = [UIColor greenColor]; 
      [[sender.subviews objectAtIndex:i] setTintColor:tintcolor]; 
     } else { 
      [[sender.subviews objectAtIndex:i] setTintColor:nil]; 
     } 
    } 
}

使用setBackgroundImage:forState:barMetrics:与UIControlStateSelected的状态。

对于UISegmentedControl您可以使用此代码

for (int i=0; i<[sender.subviews count]; i++) 
    { 
     if ([[sender.subviews objectAtIndex:i]isSelected]) 
     {    
     UIColor *tintcolor=[UIColor colorWithRed:127.0/255.0 green:161.0/255.0 blue:183.0/255.0 alpha:1.0]; 
     [[sender.subviews objectAtIndex:i] setTintColor:tintcolor]; 
     } 
     else 
     { 
      [[sender.subviews objectAtIndex:i] setTintColor:nil]; 
     } 
    }

有关背景图像

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]]; 
    self.window.backgroundColor = [UIColor whiteColor]; 
    [self.window makeKeyAndVisible];

在iOS系统7与tintColor的新问题，请尝试设置，而不是背景的颜色。这将改变segmentedControl的文字颜色。
添加segmentedControl到视图之前添加此行：

segmentedControl.backgroundColor = [UIColor greenColor];

所以你不需要这个了：

- (void)segmentAction:(UISegmentedControl *)sender 
{ 
    for (int i=0; i<[sender.subviews count]; i++) { 
     if ([[sender.subviews objectAtIndex:i]isSelected]) { 
      UIColor *tintcolor = [UIColor greenColor]; 
      [[sender.subviews objectAtIndex:i] setTintColor:tintcolor]; 
     } else { 
      [[sender.subviews objectAtIndex:i] setTintColor:nil]; 
     } 
    } 
}

请记住，未选择segmentedControl的背景颜色也将改变。但是如果你有自定义图片，你就不会看到它。

希望有所帮助。
