make easy use rac in swift
####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)
}
