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];
}
报错.png
解决方案
在
RCTScrollView.m中声明_refreshControl全局变量
@implementation RCTCustomScrollView
{
__weak UIView *_dockedHeaderView;
RCTRefreshControl *_refreshControl;
}
