React Native bundle 加载缓慢或根本不加载
React Native bundle loading slowly or not at all
问题似乎是特定于网络的，控制台日志指向两个可能导致速度下降的错误：
nw_resolver_create_dns_service_locked [C150094]
DNSServiceCreateDelegateConnection failed: NoMemory(-65539)
或
nw_socket_handle_socket_event Socket SO_ERROR [61:
Connection refused]
我尝试了两种网络配置：
- 开发 Mac 和 iPhone 在大型公司网络的同一子网 (WiFi) 上 - JS 包加载缓慢或根本不加载
- 开发 Mac（WiFi 热点）和 iPhone 之间的直接连接 - JS 包加载速度非常快
AppDelegate.m
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];

使用 RN 0.60+ 更新：react-native-xcode.sh 中的自定义设置在 运行 pod install 时被覆盖。
问题是我的 Mac 同时连接到 WiFi 和以太网（en0、en8 和 en9 都在使用中） . RCTBundleURLProvider 将 en0 作为默认值，这导致了一些奇怪的重定向。
我猜 React Native 还不支持多网络接口，所以我最终修改 AppDelegate.m 为正确的 IP。这种方法的问题是IP变化：
#ifdef DEBUG
jsCodeLocation = [NSURL URLWithString:@"http://<en8-IP-address>:8081/index.bundle?platform=ios"];
#else
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
#endif
更好的选择是在 react-native-xcode.sh:
内的打包器中修复它
# Enables iOS devices to get the IP address of the machine running Metro Bundler
if [[ "$CONFIGURATION" = *Debug* && ! "$PLATFORM_NAME" == *simulator ]]; then
IP=$(ifconfig | grep 'inet ' | grep -v ' 127.' | cut -d\ -f2 | grep '169.254.')
echo "$IP" > "$DEST/ip.txt"
fi
问题似乎是特定于网络的，控制台日志指向两个可能导致速度下降的错误：
nw_resolver_create_dns_service_locked [C150094] DNSServiceCreateDelegateConnection failed: NoMemory(-65539)
或
nw_socket_handle_socket_event Socket SO_ERROR [61: Connection refused]
我尝试了两种网络配置：
- 开发 Mac 和 iPhone 在大型公司网络的同一子网 (WiFi) 上 - JS 包加载缓慢或根本不加载
- 开发 Mac（WiFi 热点）和 iPhone 之间的直接连接 - JS 包加载速度非常快
AppDelegate.m
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
/node_modules/react-native/scripts/react-native-xcode.sh:
# Enables iOS devices to get the IP address of the machine running Metro Bundler
if [[ "$CONFIGURATION" = *Debug* && ! "$PLATFORM_NAME" == *simulator ]]; then
IP=$(ipconfig getifaddr en0)
if [ -z "$IP" ]; then
IP=$(ifconfig | grep 'inet ' | grep -v ' 127.' | cut -d\ -f2 | awk 'NR==1{print }')
fi
echo "$IP" > "$DEST/ip.txt"
fi
网络接口：
$ ifconfig | grep 'inet '
inet 127.0.0.1 netmask 0xff000000 <- Localhost
inet xxx.xxx.xxx.xxx netmask 0xfffff800 broadcast 10.10.7.255 <- Cable (en0)

使用 RN 0.60+ 更新：react-native-xcode.sh 中的自定义设置在 运行 pod install 时被覆盖。
问题是我的 Mac 同时连接到 WiFi 和以太网（en0、en8 和 en9 都在使用中） . RCTBundleURLProvider 将 en0 作为默认值，这导致了一些奇怪的重定向。
我猜 React Native 还不支持多网络接口，所以我最终修改 AppDelegate.m 为正确的 IP。这种方法的问题是IP变化：
#ifdef DEBUG
jsCodeLocation = [NSURL URLWithString:@"http://<en8-IP-address>:8081/index.bundle?platform=ios"];
#else
jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil];
#endif
更好的选择是在 react-native-xcode.sh:
# Enables iOS devices to get the IP address of the machine running Metro Bundler
if [[ "$CONFIGURATION" = *Debug* && ! "$PLATFORM_NAME" == *simulator ]]; then
IP=$(ifconfig | grep 'inet ' | grep -v ' 127.' | cut -d\ -f2 | grep '169.254.')
echo "$IP" > "$DEST/ip.txt"
