升级Xcode8后 React-Native项目遇到的错误

1 RCTWebSocket Semantic issue

• 

  打开RCTSCrollView.m Command+F 搜索@implementation RCTCustomScrollView
  只会搜索到一个结果，然后修改：

        @implementation RCTCustomScrollView
        {
              RCTRefreshControl *_refreshControl;//不管原来有什么，在原来的基础上加上这句
        }
  

• 

    //  SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);
      (void)SecRandomCopyBytes(kSecRandomDefault, keyBytes.length, keyBytes.mutableBytes);
  

2 __nw_connection_get_connected_socket_block_invoke

Xocde控制台不断输出 如下log

[] __nw_connection_get_connected_socket_block_invoke * Connection has no connected handler

1. Xcode menu -> Product -> Edit Scheme...
2. Environment Variables -> Add -> Name: "OS_ACTIVITY_MODE", Value:"disable"
3. Run again

3 Apple Mach-O Linker(Id) Error

在TARGETS下 Build setting -> Other Linker Flags ->
添加 -lc++
