遇到的問題 iOS
1. （已解決）iOS執(zhí)行 pod install 報錯 None of your spec sources contain a spec satisfying the dependency: React/Core.
Analyzing dependencies
Fetching podspec for `DoubleConversion` from `../node_modules/react-native/third-party-podspecs/DoubleConversion.podspec`
Fetching podspec for `Folly` from `../node_modules/react-native/third-party-podspecs/Folly.podspec`
Fetching podspec for `glog` from `../node_modules/react-native/third-party-podspecs/glog.podspec`
[!] CocoaPods could not find compatible versions for pod "React/Core":
In Podfile:
RNImageCropPicker (from `../node_modules/react-native-image-crop-picker`) was resolved to 0.21.3, which depends on
React/Core
None of your spec sources contain a spec satisfying the dependency: `React/Core`.
You have either:
* out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
* mistyped the name or version.
* not added the source repo that hosts the Podspec to your Podfile.
//項目根目錄執(zhí)行以下命令
grep -rl "s.dependency 'React/Core'" node_modules/ | xargs sed -i '' 's=React/Core=React-Core=g'
執(zhí)行完成沒有任何提示，之后繼續(xù)
cd iOS
pod install
2. （已解決）執(zhí)行pod install 報錯

感覺是網(wǎng)絡(luò)問題室琢，怎么解決不知道，可能是需要換源地址竞穷，可能是需要添加 hosts github的ip。就是一直重復(fù)執(zhí)行
//一直報錯一直執(zhí)行，一路爆紅終于安裝完成
pod install
3. （已解決）報錯 library not found ljanalytics
ld: library not found for -ljanalytics-ios-2.1.2
clang: error: linker command failed with exit code 1 (use -v to see invocation)
需要把
/node_modules/janalytics-react-native/ios/RCTJAnalyticsModule/janalytics-ios-2.1.2.a
文件名修改為libjanalytics-ios-2.1.2.a
4. （已解決）node報錯
node:events:491
throw er; // Unhandled 'error' event
^
Error: EMFILE: too many open files, watch

嘗試1：網(wǎng)上資料很多都是說端口占用纵顾，試過沒有效果
1洁奈、查看全部端口
sudo lsof -i
2间唉、查看端口監(jiān)聽情況
sudo lsof -i -P | grep -i "listen"
3、查看特定端口
sudo lsof -i:2425
4利术、查詢到之后通過PID進(jìn)行kill
kill PID
嘗試2：
解決辦法： 未按官方文檔要求安裝watchman
brew install watchman
5. （已解決）iOS圖片不能加載
應(yīng)用在IOS 14.0下調(diào)試無法顯示圖片
解決辦法：
修改文件RCTUIImageViewAnimated.m 270行左右
路徑如：/node_modules/react-native/Libraries/Image 下文件
- (void)displayLayer:(CALayer *)layer
{
if (_currentFrame) {
layer.contentsScale = self.animatedImageScale;
layer.contents = (__bridge id)_currentFrame.CGImage;
}
}
改成下面：
- (void)displayLayer:(CALayer *)layer
{
if (_currentFrame) {
layer.contentsScale = self.animatedImageScale;
layer.contents = (__bridge id)_currentFrame.CGImage;
}else{
[super displayLayer:layer];
}
}
6. （已解決）iOS選擇圖片上傳報錯,Domain=RCTErrorDomain Code=0 "Invalid request token
react-native庫報錯,使用patch-package這個庫可以解決修改本地庫造成的團(tuán)隊協(xié)作問題
解決辦法：
1呈野、修改react-native庫
//文件位置
that exists in node_modules/react-native/Libraries/Image/RCTImageLoader.mm
//替換一下方法所有內(nèi)容
-(id)sendRequest:(NSURLRequest *)request withDelegate:
修改成一下內(nèi)容
- (id)sendRequest:(NSURLRequest *)request withDelegate:(id<RCTURLRequestDelegate>)delegate
{
@synchronized(self) {
__block RCTImageLoaderCancellationBlock requestToken = ^{};
requestToken = [self loadImageWithURLRequest:request callback:^(NSError *error, UIImage *image) {
@synchronized(self) {
if (error) {
[delegate URLRequest:requestToken didCompleteWithError:error];
return;
}
NSString *mimeType = nil;
NSData *imageData = nil;
if (RCTImageHasAlpha(image.CGImage)) {
mimeType = @"image/png";
imageData = UIImagePNGRepresentation(image);
} else {
mimeType = @"image/jpeg";
imageData = UIImageJPEGRepresentation(image, 1.0);
}
NSURLResponse *response = [[NSURLResponse alloc] initWithURL:request.URL
MIMEType:mimeType
expectedContentLength:imageData.length
textEncodingName:nil];
[delegate URLRequest:requestToken didReceiveResponse:response];
[delegate URLRequest:requestToken didReceiveData:imageData];
[delegate URLRequest:requestToken didCompleteWithError:nil];
}
}];
return requestToken;
}
}
- 安裝patch-package
安裝比較慢，需替換源地址
//查看npm源
npm get registry
//替換淘寶源
npm config set registry http://registry.npm.taobao.org

5. （未解決）ReactNative libc++_shared.so 沖突導(dǎo)致的uncaught exception of type std::bad_cast:
這個問題場景是百度地圖插件，更新到1.0.37作者已經(jīng)沒有維護(hù)了闲延，我碰得到問題是部分Android手機打開地圖會閃退痊剖，具體的原因是jar包網(wǎng)絡(luò)監(jiān)聽方法報錯。
解決方法：
1.嘗試失敗垒玲，首先想到的是更新原生Android百度地圖SDK陆馁，但是會報動態(tài)庫編譯libc++_shared.so沖突，packagingOptions 排除'lib/x86/libc++_shared.so' 會報如題錯誤合愈。查資料一般都是重新編譯三方庫叮贩，知識盲區(qū)只能放棄了。
2.根據(jù)錯誤修改現(xiàn)在代碼佛析，定位報錯信息發(fā)現(xiàn)是BaiduLBS_Android.jar網(wǎng)絡(luò)監(jiān)聽報錯益老，看到這大概有了思路，簡單粗暴直接把相關(guān)的方法干掉寸莫。于是就有了如何修改jar包單個class文件捺萌，親歷可解決部分問題，步驟上面方法已經(jīng)有了膘茎，這里說下注意的地方：
注意的地方：
//修改后的java打包成class文件桃纯，
javac -classpath android/app/src/e.java
這個有個坑，一般java文件都會引入Android.jar或者其他的文件披坏，直接轉(zhuǎn)會報找不到文件态坦，需要將相關(guān)的jar包放到同級,多個jar包可以用: 號連接，這里是mac的方法棒拂，Windows好像是伞梯；分號，沒有試過
javac -classpath android.jar:BaiduLBS_Android.jar e.java
完整步驟：
1.解析jar文件成class文件
jar xf BaiduLBS_Android.jar
2.使用工具或vscode安裝插件帚屉，將class文件解析成java可讀性強的文件谜诫，并打包成class
javac -classpath android.jar:BaiduLBS_Android.jar e.java
3.替換修改的class，并將所有class文件打包成jar文件涮阔，cd 到class文件目錄并執(zhí)行
jar -cvf BaiduLBS_Android.jar ./
