iOS 13适配深色模式【设置UITabBarItem上title颜色& 适配第三方库QMUIKit在iOS13的问题】

 

前言 I、设置UITabBarItem上title颜色

        self.tabBar.unselectedItemTintColor = ktabNorTextColor;

self.tabBar.tintColor = ktabSelectedTextColor;

•  

1.1 适配代码

    // 适配iOS13导致的bug
if (@available(iOS 13.0, *)) {
// iOS 13以上
//        self.tabBar.tintColor = ;
self.tabBar.unselectedItemTintColor = ktabNorTextColor;

self.tabBar.tintColor = ktabSelectedTextColor;
//        self.tabBar.unselectedItemTintColor = ;

//        UITabBarItem *item = [UITabBarItem appearance];
//        item.titlePositionAdjustment = UIOffse/tMake(0, -2);
//        [item setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12]} forState:UIControlStateNormal];
//        [item setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12]} forState:UIControlStateSelected];
} else {
//        // iOS 13以下
//        UITabBarItem *item = [UITabBarItem appearance];
//        item.titlePositionAdjustment = UIOffsetMake(0, -2);
//        [item setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12], NSForegroundColorAttributeName:RGB_HEX(0x999999)} forState:UIControlStateNormal];
//        [item setTitleTextAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12], NSForegroundColorAttributeName:RGB_HEX(0xfb5400)} forState:UIControlStateSelected];
//设置文字样式
        NSMutableDictionary *textAttr = [NSMutableDictionary dictionary];
        textAttr[NSForegroundColorAttributeName] = ktabNorTextColor;
[childVC.tabBarItem setTitleTextAttributes:textAttr forState:UIControlStateNormal];
//选择状态的文字颜色样式
        NSMutableDictionary *selectedTextAttr = [NSMutableDictionary dictionary];
[selectedTextAttr setValue:ktabSelectedTextColor forKey:NSForegroundColorAttributeName];



[childVC.tabBarItem setTitleTextAttributes:selectedTextAttr forState:UIControlStateSelected];

  II 、适配第三方库QMUIKit在iOS13的问题

适配第三方库QMUIKit在iOS13的问题【 -[_UINavigationBarContentView setDirectionalLayoutMargins:],】“KVC访问私有属性”

升级Xcode之后，今天在iOS13中打开app的时候闪退，错误信息是*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Client error attempting to change layout margins of a private view'

*** Assertion failure in -[_UINavigationBarContentView setDirectionalLayoutMargins:]

• 解决方案是更新第三方库

-> Installing QMUIKit 4.0.4 (was 3.2.1 and source changed to `https://cdn.cocoapods.org/` from `https://github.com/cocoapods/specs.git`)
  $ /usr/bin/git ls-remote https://github.com/Tencent/QMUI_iOS.git master
  2416a78cac2b447e8895e1260b2547f1764240c0	refs/heads/master
