RN笔记-ios原生嵌入rn框架的小坑

RN插件嵌入到现有iOS原生应用时，按照http://www.jianshu.com/p/e6310f9ea31b 配置完了之后运行时，会提示_refreshControl变量不存在，如下图所示

问题

- (void)setRefreshControl:(RCTRefreshControl *)refreshControl
{
  if (_refreshControl) {
    [_refreshControl removeFromSuperview];
  }
  _refreshControl = refreshControl;
  [self addSubview:_refreshControl];
}

解决方案

在RCTScrollView.m中声明_refreshControl全局变量

@implementation RCTCustomScrollView
{
  __weak UIView *_dockedHeaderView;
    RCTRefreshControl *_refreshControl;
}
