Ios React本机RCTCustomScrollView在升级到Xcode8后损坏

Ios React本机RCTCustomScrollView在升级到Xcode8后损坏,ios,objective-c,xcode,facebook,react-native,Ios,Objective C,Xcode,Facebook,React Native,显然,在升级到Xcode 8时,对于react native而言。我已经按照指南修复了我遇到的错误,但当我的应用程序尝试加载组件时,仍然会出现以下错误 [RCTCustomScrollView refreshControl]:无法识别的选择器发送到实例0x16099e00 我的RCTScrollView.m中的代码似乎是每个人都认为导致问题的原因,如下所示: - (void)setRefreshControl:(RCTRefreshControl *)refreshControl { if

显然,在升级到Xcode 8时,对于react native而言。我已经按照指南修复了我遇到的错误,但当我的应用程序尝试加载
组件时,仍然会出现以下错误

[RCTCustomScrollView refreshControl]:无法识别的选择器发送到实例0x16099e00

我的
RCTScrollView.m
中的代码似乎是每个人都认为导致问题的原因,如下所示:

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

- (void)removeReactSubview:(UIView *)subview
{
  if ([subview isKindOfClass:[RCTRefreshControl class]]) {
  _scrollView.refreshControl = nil;
  } else {
    RCTAssert(_contentView == subview, @"Attempted to remove non-existent subview");
    _contentView = nil;
    [subview removeFromSuperview];
  }
}
当我在运行iOS 10.1.1的设备上运行时,一切似乎都正常,但当我在运行9.3的设备上尝试时,它在尝试加载
时崩溃

重要提示
-我运行的是react native 0.28,目前无法升级,因此我必须手动进行修复。

我找到的唯一解决方案是,转到RCTScrollView.m,将
[\u scrollView refreshControl]
替换为
[\u scrollView respondsToSelector:@selector(refreshControl)]

-(NSArray*)子视图
{
if(_contentView&&[_scrollviewrespondstoselector:@selector(刷新控制)]){
返回@[\u contentView,[\u scrollView refreshControl];
}
返回@u contentView?@[\u contentView]:@[];
}

我知道这是一篇比较老的帖子,但是对于Xcode 8、iOS 9.3(iPad 2/iPad Mini)、React Native 0.24.1,我在RCTScrollView.m中做了这个修改作为修复

@implementation RCTCustomScrollView
{
  __weak UIView *_dockedHeaderView;

 // Added the following line
 RCTRefreshControl *_refreshControl;
}
// Also added this
@synthesize refreshControl = _refreshControl;

这对我很有帮助。非常感谢
@implementation RCTCustomScrollView
{
  __weak UIView *_dockedHeaderView;

 // Added the following line
 RCTRefreshControl *_refreshControl;
}
// Also added this
@synthesize refreshControl = _refreshControl;
