iOS 13适配

1.解决 TabBar 选中文字颜色为蓝色问题

只需要设置 UITabBarItem 的未选中颜色即可

if (@available(iOS 13.0, *)) {

        [[UITabBar appearance] setUnselectedItemTintColor:[UIColor whiteColor]];

    }

2.解决不再允许通过 KVC 的方式去访问私有属性

[_searchController.searchBar setValue:@"取消" forKey:@"cancelButtonText"] 去掉

[_searchController.searchBar setValue:@"取消" forKey:@"cancelButtonText"]

3. UISegmentedControl

默认样式变为白底黑字，如果设置修改过颜色的话，页面需要修改。

原本设置选中颜色的 tintColor 已经失效，新增了 selectedSegmentTintColor 属性用以修改选中的颜色。

改变文字

NSDictionary *selecteddic = [NSDictionary dictionaryWithObjectsAndKeys:D_NavBarTintColor,NSForegroundColorAttributeName,nil];
        [_segmentControl setTitleTextAttributes:selecteddic forState:UIControlStateSelected];
        NSDictionary *dics = [NSDictionary dictionaryWithObjectsAndKeys:[UIColor whiteColor],NSForegroundColorAttributeName,nil];
        [_segmentControl setTitleTextAttributes:dics forState:UIControlStateNormal];
