Question

我提到了How can I fix my install of ReactiveCocoa (with CocoaPods)?，但它没有帮助。基本上，如果我创建一个新项目并执行这些步骤：

1) sudo gem install cocoapods
2) pod init
3) Change Podfile to 

# platform :ios, ‘8.0’
target 'Test Project' do
pod 'ReactiveCocoa'
end
4) pod install

效果很好。

但是，当我尝试在下面的示例中对我当前的项目执行此操作时，它不起作用..

in .h

@property (strong, nonatomic) NSString *testString;

在viewDidLoad ..

self.testString = @"hello";
[RACObserve(self, testString) subscribeNext:^(NSString *newString) {
    NSLog(@"%@", newString);
}];
self.testString = @"yellow";

我收到错误日志：

2015-04-23 16:13:49.386 MyProjectName[69489:1451941] -[PlayViewController rac_valuesForKeyPath:observer:]: unrecognized selector sent to instance 0x7f987b4a0010
2015-04-23 16:13:49.443 MyProjectName[69489:1451941] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[PlayViewController rac_valuesForKeyPath:observer:]: unrecognized selector sent to instance 0x7f987b4a0010'

我看到他最终只是把它移植到一个工作项目，这是不必要的。任何帮助/问题将不胜感激。感谢
