APP在调试模式下崩溃，但在iOS 8上的发布模式下运行正常

Question

APP work fine on iOS 9 and iOS 10.However,on iOS 8,it crash when run in debug mode but work fine in release mode.

The error code is:

[RACObserve(self.scrollView, contentOffset) subscribeNext:^(id x) {
    NSInteger currentTableViewTag = self.scrollView.contentOffset.x / screenWidth;
    NSLog(@"current tableView tag：%ld",(long)currentTableViewTag);
    self.currentTableView = [self viewWithTag:currentTableViewTag];
}];

The console log info is:

-[UIScrollView rac_valuesForKeyPath:observer:]: unrecognized selector sent to instance 0x178153f0

The ReactiveCocoa version is:

pod 'ReactiveCocoa','~>2.1.8'

My build setting is:

My try:

1. Change RAC version to 2.5 but build faild.
2. Search on Google but no want answer.

My question is:

What's wrong with ReactiveCocoa?Why in release mode it is OK but in debug it's crash on iOS 8?

Hope someone can give an advice.

当我将Pods放入.gitignore时，然后进行pod安装即可解决此问题。
