RACSwift

make easy use rac in swift

• EasyIOS
• ReactiveCocoa

####补丁:解决Swift中取消OC的复杂弘定义导致的ReactiveCocoa无法在Swift中使用的问题

• 1.添加 RACSwift.swift 到swift 项目中
• 2.替换 RACCommand.m、RACSignal+Operations.h、RACSignal+Operations.m 三个文件
• 3.设置Objective-C Bridging Header为${PODS_ROOT}/Headers/EasyIOS/swift-bridge.h

###demoForRACSwift

这个demo基于beta5，里面存在一个swift访问objc的NSDictionary属性时出现crash问题，暂时没用找到解决方案，如果有人可以帮忙，不胜感激。

位置在DemoSceneModel.swift文件里：

var output =  self.goodsListRequest.output as NSDictionary;

###Usage

RAC In Objective－C:

RAC(self.collectionView,page) = RACObserve(self.collectionView,page);

In Swift:

RAC(self.collectionView,"page") <= RACObserve(self.collectionView,"page")
RACObserve(self.collectionView,"page") => RAC(self.collectionView,"page")

---

RACObserve In Objective－C:

    [[[RACObserve(self.collectionView, page)
     map:^NSString*(NSNumber* newPage) {
         return @"123";
     }]
     filter:^BOOL(NSString* newPage) {
         return false;
     }]
     subscribeNext:^(NSString* text) {
         NSLog(@"%@",text);
     }];

In Swift:

    RACObserve(self.collectionView,"page")
    .mapAs{
        (newpage:NSNumber) -> NSString in
        return "123"
    }
    .filterAs{
        (newpage:NSString) -> Bool in
        return false
    }
    .subscribeNextAs{
        (text:String) -> () in
        println(text)
    }
