IOS27 适配 手势滑动返回导航栏向上飘

其实真的那个液态UI很丑。。并不好看。。但是IOS27直接彻底关闭了UIDesignRequiresCompatibility兼容APP只能进行全方位适配1、更新xcode后项目无法启动表现为项目目录左侧点击项目名称右侧切换general选项标签时直接崩处理方法删除info.plist文件中的此KEY现在原因不知道为何很烂很烂。。。keyNSLocationTemporaryUsageDescriptionDictionary/key dict keypurposeKey4changeInfo/key string允许使用精确的定位功能,以便考勤打卡?/string /dict2、UIWindow的初始化及管理如最新SDK实现window已经被补刀避免后期再次出现补刀有必要抽出来实现一个子类这样做的好处是后面有调整直接在子类实现另一个就是Appdelegatge已经不允许初始化UIWindow而是放在了SceneDelegate所以导致全局读取window的方法也失效所以这里也有必要暴露一个方法来全面替换之前通过[[[UIApplication sharedApplication] delegate] window]来读取的代码// // UIRootWindow.h // // Created by carbonzhao on 2024/3/21. // #import UIKit/UIKit.h NS_ASSUME_NONNULL_BEGIN interface UIRootWindow : UIWindow //出现控制器推出显示时显示在window上的view会被移除 (void)addSubview:(UIView *)view;

UIWindowScene *windowScene (UIWindowScene *)scene; self.window [[UIRootWindow alloc] initWithWindowScene:windowScene]; [self.window makeKeyAndVisible]; //移植你之前的逻辑 self.window.rootViewController XXX }此文件中以下4个方法如果有实现逻辑在SceneDelegate对应的方法中调用具体见上述3中的实现避免大量迁移代码官方文档Transitioning to the UIKit scene-based life cycle | Apple Developer Documentation5、UITabbarcontroller自定义的适配- (void)viewDidLoad { [super viewDidLoad]; //CYLTabBar继承于UITabbar CYLTabBar *aBar [[CYLTabBar alloc] init]; [self setValue:aBar forKey:tabBar]; }//CYLTabBar实现父类方法若发现在添加_UITabBarPlatterView直接忽略则相当于间接拒绝了新增的交互及UI - (void)addSubview:(UIView *)view { if (![view isKindOfClass:NSClassFromString(UITabBarButton)] ![view isKindOfClass:NSClassFromString(UIKit._UITabBarPlatterView)]) { [super addSubview:view]; } }若非自定义tabbar则思路一致你直接进行实现即可6、导航栏左、右barbutton的适配interface UINavigationItem (ios27) endvoid aeMethodSwizzle(Class c,SEL origSEL,SEL overrideSEL) { Method origMethod class_getInstanceMethod(c, origSEL); Method overrideMethod class_getInstanceMethod(c, overrideSEL); //运行时函数class_addMethod 如果发现方法已经存在会失败返回也可以用来做检查用: if(class_addMethod(c, origSEL, method_getImplementation(overrideMethod),method_getTypeEncoding(overrideMethod))) { //如果添加成功(在父类中重写的方法)再把目标类中的方法替换为旧有的实现: class_replaceMethod(c,overrideSEL, method_getImplementation(origMethod), method_getTypeEncoding(origMethod));
