架构 x86_64 的未定义符号:将扩展目标添加到本机项目后 [英] Undefined symbols for architecture x86_64: after adding an extension target to a react-native project

问题描述

我使用 react-native init 创建了一个 react-native 项目然后，我使用 File -> new -> target -> Action Extension 向该项目添加一个动作扩展，名称为Stash"我尝试添加一个从 UIView 继承并包含 RCTRootView 的 StashView，如 与现有应用说明集成:

I created a react-native project using react-native init I then add an action extension to that project using File -> new -> target -> Action Extension, with the name "Stash" I try adding a StashView that inherits from UIView, and contains an RCTRootView, as instructed in the Integration with Existing App instructions:

Stash/StashView.h:

Stash/StashView.h:

#import <UIKit/UIKit.h>

@interface StashView : UIView

@end

Stash/StashView.m:

Stash/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

编译时报错:

体系结构 x86_64 的未定义符号:
_OBJC_CLASS_$_RCTRootView"，引用自:StashView.o ld 中的 objc-class-ref:找不到体系结构 x86_64 clang 的符号:错误:链接器命令失败，退出代码1(使用 -v 查看调用)

我做错了什么?构建设置中的某些内容?

What am I doing wrong? Something in the build settings?

推荐答案

想通了！

基于此处的答案

我必须在扩展的构建阶段打开链接二进制文件和库胡萝卜，并将所有反应库添加到其中:

I had to open the Link Binary with Libraries carrot in the Build Phases of the extension, and add all of the react libraries to it:
