iOS 链式编程思想

链式编程思想不用啰嗦哈，

例如将计算方法，用链方式串联起来，实现可以参考下

github:  RAC_链式编程

- (void)viewDidLoad {
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
    
    
    int iResult = [NSObject makeCaculators:^(CaculatorMaker *make) {
        
        make.add(1).add(2).add(3).divide(2);
        
    }];
    
    NSLog(@" 1===== %d",iResult);
    
    CaculatorMaker *maker = [[CaculatorMaker alloc]init];
    
    NSInteger reslut =
    [[[maker caculator:^int(int result) {
        result += 2;
        result *= 5;
        return result;
        
    }] equle:^BOOL(int result) {
        
        return result = 10;
        
    }] isEqule];
    
    
    NSLog(@" 2===== %ld",(long)reslut);
}
