   同样也是有这个问题，应该不止这一处

   这是 iOS 26 后 nav 的contentView 变更导致 KVC 找不到的问题, 具体目前只能 fork 分支自己修改, 或者你可以临时修改, 找到pods 文件中的:
   `- (UIView *)qmui_contentView {
   return [self valueForKeyPath:@"visualProvider.contentView"];
   }

   将该方法修改为:

   • (UIView *)qmui_contentView {
     // return [self valueForKeyPath:@"visualProvider.contentView"];
     UIView *contentView = nil;
     if (@available(iOS 26.0, *)) {
     contentView = nil;
     } else {
     // 老版本走原来的方法，但是用 try 兜底
     @Try {
     contentView = [self valueForKeyPath:@"visualProvider.contentView"];
     } @catch (NSException *exception) {
     contentView = nil;
     }
     }
     if (contentView) {
     return contentView;
     }

      // 按类名查找 _UINavigationBarContentView
      Class class__NavigationBarContentView = NSClassFromString([NSString qmui_stringByConcat:@"_", @"UINavigationBar", @"ContentView", nil]);
      if (class__NavigationBarContentView) {
          contentView = [self subviewWithClass:class__NavigationBarContentView];
          if (contentView) {
              return contentView;
          }
      }
     
      // 按类名查找 UIKit.NavigationBarContentView
      Class class_UIKit_NavigationBarContentView = NSClassFromString(@"UIKit.NavigationBarContentView");
      if (class_UIKit_NavigationBarContentView) {
          contentView = [self subviewWithClass:class_UIKit_NavigationBarContentView];
          if (contentView) {
              return contentView;
          }
      }
     
      // 查找名字中包含 "ContentView" 的 view
      NSString *classNamePart_ContentView = @"ContentView";
      contentView = [self subviewWithClassNamePart:classNamePart_ContentView];
      if (contentView) {
          return contentView;
      }
     
      return nil;
     

     }

     • (UIView *)subviewWithClass:(Class)aClass {
       if (aClass) {
       for (UIView *sub in self.subviews) {
       if ([sub isKindOfClass:aClass]) {
       return sub;
       }
       // 有的系统层次里 contentView 不是直接子视图，尝试再向下查找一层
       for (UIView *sub2 in sub.subviews) {
       if ([sub2 isKindOfClass:aClass]) {
       return sub2;
       }
       }
       }
       }
       return nil;
       }

   • (UIView *)subviewWithClassNamePart:(NSString *)classNamePart {
     for (UIView *sub in self.subviews) {
     NSString *className = NSStringFromClass(sub.class);
     if ([className containsString:classNamePart]) {
     return sub;
     }
     for (UIView *sub2 in sub.subviews) {
     NSString *className2 = NSStringFromClass(sub2.class);
     if ([className2 containsString:classNamePart]) {
     return sub2;
     }
     }
     }
     return nil;
     }`
     重新运行即可

   替换
   - (UIView *)qmui_contentView{...}的实现:
   ↓
   - (UIView *)qmui_contentView {
       // 优先尝试原始 KVC 方式（iOS 26 以下）
       if (@available(iOS 26.0, *)) {
           // iOS 26+ 不使用 KVC，走下面的兜底逻辑
       } else {

               }

               NSLog(@"QMUI: Failed to get contentView via KVC: %@", exception);
           }
       }
       
       // iOS 26+ 或 KVC 失败时的兜底方案
       UIView *contentView = [self qmui_findContentView];
