React-Native0.32以下版本xcode8中报错解决方法

RCTSRWebSocket.m报错

Ignoring return value of function declared with warn_unused_result attribute

• 这个报错在此文件中有两处，代码
  SecRandomCopyBytes(kSecRandomDefault, sizeof(uint32_t), (uint8_t *)mask_key);

• 修改为
  (void)SecRandomCopyBytes(kSecRandomDefault, sizeof(uint32_t), (uint8_t *)mask_key);

前面加上(void)。

RCTScrollView.m 报错

Use of undeclared identifier '_refreshControl'; did you mean 'refreshControl'?

@implementation RCTCustomScrollView
{
  __weak UIView *_dockedHeaderView;
  RCTRefreshControl *_refreshControl;   // 加入此行
}
