紀錄了Ryan在React Native上遇到的在各種錯誤。
透過的方式將Google Map App 開啟
我們會在APP中，開啟Google Map App讓App接手導航的任務，那要怎麼開啟他呢？
var rout = "comgooglemaps://?saddr=12.3456,22.4456&daddr=13.2256,23.3456&directionsmode=driving;"
_mapActive(way) {
return Linking.openURL(rout).catch(err => Alert.alert('哎呦～發生錯誤！', err));
}
首先是設定『comgooglemaps』，然後在info.plist上，新增
<key>LSApplicationQueriesSchemes</key>
<array>
<string>comgooglemaps</string>
</array>
這樣才能順利開啟google map App
APP無法外連外部網路
App Transport Security has blocked a cleartext HTTP (http://) resource load since it is insecure.
iOS預設狀態下，是無法自由存取外部資源的，若有需要的話，需將設定開啟，不過話說回來，這年頭APP不能純取網路資料，豈不是半殘？可以領殘障手冊了。
主要是要在info.plist中，將設定打開
或直接貼入也可以
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key><true/>
</dict>
這樣就可以讓APP存取網路資源。
當你在模擬器執行ＡＰ無誤之後，想在實體設備上面ＲＵＮ看看，出現了這個錯誤
若模擬器環境底下，訪問localhost都正常，但一旦要在實機上面執行，就出現錯誤，這篇的資訊多少可以參考
Ensure the following:
- Node server is running and available on the same network - run 'npm start' from react-native root
這是因為iOS9有一些安全性的議題，要進行底下設定。
先檢視你的ＭＡＣ的ＩＰ，因為ＭＡＣ是宿主，要由設備來訪問
可以在ＭＡＣ的與Browser連接上面這個連結，
jsCodeLocation = [NSURL URLWithString:@"http://xxxxxxx:8081/index.ios.bundle?platform=ios&dev=true"];
若順利連得上，表示宿主沒問題囉
在瀏覽器上，看到這個畫面，表示服務順利的啟動，有回應
若在實機的Browser也可以連得到，那表示實機可以連得到宿主
但開啟ＡＰＰ，還是出現紅色畫面，表示瀏覽器連得到，ＡＰＰ連不到這就是ＡＰＰ的安全性設定問題了。
到info.plist 加入
<key>NSAppTransportSecurity</key>
<dict>
<key>NSAllowsArbitraryLoads</key><true/>
</dict>
到目前為止，你應可以在實體機器上面把app跑起來了。
加碼一招，若你還需要在app進行debug，那修改下面這個步驟
該步驟是修改 RCTWebSocketExecutor.m 這個檔案
試試看吧！
permission denied,
React Natice 相關環境建置完成之後，建置專案出現錯誤訊息：

看來是目錄授權問題，可以透過Command-Line執行
sudo chown -R $(whoami)~/.npm
升级XCode8之後，出現了一堆問題
近日將xcode升級到8之後，出現了暴多的問題，首先是
RN 0.32以下版本Xcode 出錯解決辦法
RCTSRWebSocket.m出錯
Ignoring return value of function declared with warn_unused_result attribute
這個錯誤出現在兩個地方，稍微調整一下
SecRandomCopyBytes(kSecRandomDefault, sizeof(uint32_t), (uint8_t *)mask_key);
修改為
(void)SecRandomCopyBytes(kSecRandomDefault, sizeof(uint32_t), (uint8_t *)mask_key);
前面加上(void)。
重新編譯之後，又出現
共九個錯誤～安娘隈...

光看到，手腳就冷一半了...
還好有解～～
在 Target => Build Phases 加入
libstdc++.tbd
libc++.tbd
要注意的是，target裡面的Project都需要加入喔！
應該就可以解決手腳冰冷的bug問題了
