Colors 如何在iOS 7.1上更改UITabBar上图像和标签的颜色？

如何在iOS 7.1上更改

uitabar

上图像和标签的颜色？在iOS 7上，我可以通过

Tint

property来实现。但在iOS 7.1上，它不起作用。

uitabaritem从来没有

tint

属性。没有内置类具有

tint

属性。这里没有什么变化

---

在iOS 7和7.1中，UITabBar具有

tintColor

属性，因为它是UIView。

这会在选中时更改图像和标签的色调

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[UITabBar appearance] setTintColor:[UIColor redColor]];
}

---

它在iOS 7和iOS 7.1中的工作方式相同

在AppDelegate中：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Add this if you only want to change Selected Image color 
    // and/or selected image text
    [[UITabBar appearance] setTintColor:[UIColor redColor]];

    // Add this code to change StateNormal text Color,
    [UITabBarItem.appearance setTitleTextAttributes:
    @{NSForegroundColorAttributeName : [UIColor greenColor]} 
    forState:UIControlStateNormal];

    // then if StateSelected should be different, you should add this code
    [UITabBarItem.appearance setTitleTextAttributes:
    @{NSForegroundColorAttributeName : [UIColor purpleColor]} 
    forState:UIControlStateSelected];

    return YES;
}

UIImageRenderingModeAutomatic,          // Use the default rendering mode for the context where the image is used    
UIImageRenderingModeAlwaysOriginal,     // Always draw the original image, without treating it as a template
UIImageRenderingModeAlwaysTemplate,     // Always draw the image as a template image, ignoring its color information

在每个ViewController中：（如果要更改未选择的图像颜色）

此代码的线索是“UIImageRenderingModeAlwaysOriginal”：

苹果文档提供的渲染模式：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    // Add this if you only want to change Selected Image color 
    // and/or selected image text
    [[UITabBar appearance] setTintColor:[UIColor redColor]];

    // Add this code to change StateNormal text Color,
    [UITabBarItem.appearance setTitleTextAttributes:
    @{NSForegroundColorAttributeName : [UIColor greenColor]} 
    forState:UIControlStateNormal];

    // then if StateSelected should be different, you should add this code
    [UITabBarItem.appearance setTitleTextAttributes:
    @{NSForegroundColorAttributeName : [UIColor purpleColor]} 
    forState:UIControlStateSelected];

    return YES;
}

UIImageRenderingModeAutomatic,          // Use the default rendering mode for the context where the image is used    
UIImageRenderingModeAlwaysOriginal,     // Always draw the original image, without treating it as a template
UIImageRenderingModeAlwaysTemplate,     // Always draw the image as a template image, ignoring its color information
