体系结构x86_64的未定义符号：将扩展目标添加到反应原生项目之后
我使用react-native init 创建了react-native项目然后使用File - > new - > target - > Action为该项目添加一个操作扩展拓，名称为 “藏匿” 我尝试添加来自继承的UIView，并包含一个RCTRootView StashView，按照指示在Integration with Existing App instructions：体系结构x86_64的未定义符号：将扩展目标添加到反应原生项目之后
藏匿/ StashView.h：
#import <UIKit/UIKit.h>
@interface StashView : UIView
@end
藏匿/ StashView .m：
#import "StashView.h"
#import "RCTRootView.h"
@implementation StashView
- (void)awakeFromNib {
NSString *urlString = @"http://localhost:8081/stash.ios.bundle";
NSURL *jsCodeLocation = [NSURL URLWithString:urlString];
RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation
moduleName: @"Stash"
launchOptions:nil];
[self addSubview:rootView];
rootView.frame = self.bounds;
}
@end
当我编译，我得到的错误：
Undefined symbols for architecture x86_64:
"_OBJC_CLASS_$_RCTRootView", referenced from: objc-class-ref in StashView.o ld: symbol(s) not found for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

我在做什么错？在构建设置中的东西？
