iOS18.0 iPad适配问题-tabbar

问题

系统的tabbar样式变更造成底部自定义的tabbar无法正常显示

解决方案

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 180000
        if (@available(iOS 18.0, *)) {
            if (UIDevice.currentDevice.userInterfaceIdiom == UIUserInterfaceIdiomPad) {
                self.mode = UITabBarControllerModeTabBar;
                self.traitOverrides.horizontalSizeClass = UIUserInterfaceSizeClassUnspecified;
                NSString *tabContainerClassName = [NSString stringWithFormat:@"%@%@%@", @"_UITab", @"Container", @"View"];
                for (UIView *subview in self.view.subviews) {
                    if ([NSStringFromClass(subview.class) isEqualToString:tabContainerClassName]) {
                        [subview setHidden:YES];
                    }
                }
            }
        }
    #endif

判定iPad及18.0以上系统，重新对UITabbarController的子类进行模式重置和底部方向设定，去除二级controller存在_uitab等子类.
